Enterprise AI enters its next phase as security overtakes innovation

A Colt survey of 1,020 IT leaders finds security and resilience now rank above new AI features, and 96% say AI already strains their networks.

Luxembourg firms that add AI to calls and contact centres face the same pressure: more traffic, more cloud links and more security checks. The survey covers large companies, but the lesson also applies to smaller ones. Before adding AI call transcription or voice agents, check that your internet line and SIP trunk have spare capacity, and that you can document where call data is stored for NIS2 and GDPR. The sample includes the Netherlands, France and Germany, but there is no separate data for Luxembourg or Belgium.

Why the phone call remains an essential sales tool alongside email

Mixvoip argues that B2B sales teams get more replies and faster deals when they combine phone calls with email.

For sales teams in Luxembourg and the Greater Region, the useful question is not the response figures but whether calls are logged where managers can see them. Many phone systems can push call records into a CRM, but recording calls in Luxembourg, Belgium, France or Germany needs a clear legal basis and a notice to the caller under GDPR. When you compare cloud phone offers, check CRM integration, recording consent options and where call data is stored, not only the price per user.

Effizienzwerk Voice: The Intelligent AI Phone Assistant for the innovaphone PBX

A new partner app adds an AI phone assistant to the innovaphone PBX that answers calls 24/7, books appointments and routes callers to the right team.

Many Luxembourg SMEs lose calls outside office hours or when reception is busy, so an AI assistant inside the existing phone system can fill that gap without moving to a new platform. Because it is a partner app, ask your installer who hosts the AI, where call data and transcripts are processed, and whether this meets GDPR and your sector rules. Also test it with callers who switch between French, German and English, and check the pricing model before a wide rollout.

Size Your 3CX AI Server for Today, Scale It for Tomorrow

3CX published a guide to sizing its AI Server for call and voicemail transcription, based on recorded minutes, measured speed and busy-hour peaks.

For Luxembourg businesses that record calls, the size of the transcription server decides how quickly transcripts arrive and how well the system copes with busy hours. If the AI server is self-hosted, call audio can stay inside the company or with a local partner, which can help with GDPR and sector rules in finance and health. Before buying hardware, ask your installer to test real recordings in French, German and English, since speed can differ by language. Also check which 3CX licence edition includes AI transcription.

AI phone answering: where to start on your business number

Voxbi advises starting AI phone answering with after-hours and overflow calls, keeping a route to a person and running a short pilot.

Small businesses in Luxembourg are starting to put AI answering on their main number, and the main risk is a caller who cannot reach a person. Starting with after-hours and overflow calls keeps that risk low. Before a pilot, check that your phone system supports a clear fallback chain to a colleague, a queue and voicemail, and that transcripts are kept only as long as needed. The EU AI Act also requires that callers are told they are speaking to a machine. Compare handover and data controls across providers, not only the AI features.

Music on hold: a guide for your business phone system

Voxbi explains how to choose, license and test music on hold for business phone queues in France, Belgium and Luxembourg.

Music on hold looks like a small detail, but a business in Luxembourg that plays commercial music in its queues may owe fees to Sacem Luxembourg, and a company working across borders may need separate clearance in Belgium or France. Royalty-free tracks or a short recorded message avoid most of this. Most cloud phone systems let you upload a file per queue. Before you change the audio, check waiting times and staffing, because long holds usually point to a routing or staffing problem, not to the music.

innovaphone at it-sa Expo&Congress 2026 in Nuremberg: Three Days Dedicated to IT Security

innovaphone showed its secure business communication tools at the it-sa IT security fair in Nuremberg from 27 to 29 October 2026.

IT security now plays a bigger role when businesses in Luxembourg and Germany choose a phone system, and trade fairs like it-sa show how vendors present it. For buyers, the practical step is to ask any vendor for concrete proof: call encryption, update cycles, hosting location and certifications. This matters more under NIS2, which brings many medium-sized firms in the Greater Region into scope for supplier security checks.

Your Existing Customers Are Your Next Growth Opportunity

3CX advises its resellers to review existing customers regularly and offer add-ons such as CRM links, call reports, queues and AI agents.

For businesses in Luxembourg and the Greater Region that use 3CX, this shows that resellers are encouraged to propose more services after installation. A regular review can be useful, but each add-on can mean a different edition, higher yearly licence costs or call data processed by AI features. Before you accept an upgrade, ask what problem it solves, what it costs per year and where call recordings or transcripts are stored.

DEEP: Placer le cloud et l'IA au service de la transformation métier

DEEP, part of POST Luxembourg, says firms should pick public, private or sovereign cloud per workload and plan AI projects for real business value.

For Luxembourg firms, the choice of cloud model now decides where business data, call recordings and AI tools are hosted and which law applies to them. A per-workload approach lets a company keep sensitive data on a sovereign or private platform and use public cloud for less critical tasks. Before signing, check data location, exit terms and the full cost of running AI at scale, since a successful pilot does not prove a return. The same questions apply when you add AI transcription or voice agents to a phone system.

Datacenter.eu launches cross-border AI Accelerator for start-ups and welcomes Easylab AI as its first company supporte

Datacenter.eu opens an AI Accelerator for start-ups in Luxembourg, Belgium, Germany and France, with Easylab AI as its first supported company.

The programme gives AI start-ups in Luxembourg and the Greater Region a route to market that pairs funding with locally hosted infrastructure. For business buyers, it points to more AI products, such as autonomous agents for finance, legal and insurance teams, that can run with data kept in Luxembourg. Companies that use AI with voice, contact centre or CRM tools should check where such services are hosted and which data protection terms apply. The model includes a minority stake and a preferred infrastructure partner role, so start-ups and their customers should look at how that link is set up.

Souveraineté numérique : garder le contrôle à l'ère du cloud et de l'IA

In an ITnation talk, Proximus NXT and Clarence explain that digital sovereignty covers law, hardware and supply chains, not only data location.

Businesses in regulated sectors in Luxembourg are being asked where their cloud, AI and phone data sit and which law applies to them. The discussion is a reminder that a local data centre is only one part of the answer. When you choose a cloud phone system or contact centre with AI features, ask where recordings and transcripts are processed, who runs the AI models, and whether the service keeps working if a foreign supplier cuts access. These questions also feed into NIS2 planning.

Good governance requires alternatives

Relying on one supplier for hosting, connectivity or backups is an underrated risk, and adding a second option is part of good IT governance, the author argues.

For many Luxembourg companies, the phone system is the most visible single point of failure: the same supplier often provides the numbers, the Cloud PBX and the internet line it runs on. A simple first step is a backup access line from a second operator, for example fibre from one provider and 4G or 5G from another such as POST, Tango or Orange. Before signing, it is also worth asking a Cloud PBX provider how calls are rerouted to mobiles during an outage and how quickly numbers can be ported out.

One MS Teams Tenant, Three Voice Paths: Choosing The Right Architecture In 2026

Microsoft Teams

A Mixvoip-sponsored Silicon Luxembourg piece compares Teams Calling Plans, Operator Connect and Direct Routing for Luxembourg firms.

For a Luxembourg company on Microsoft Teams, the choice of voice path decides who holds its numbers, who is responsible for 112 routing and what goes into its DORA ICT register. Teams lets one tenant mix Calling Plans, Operator Connect and Direct Routing user by user, so a firm with staff in Luxembourg, Belgium, France and Germany does not need one path for everyone. The article is sponsored by Mixvoip, which sells Direct Routing, so buyers should compare quotes for all three options before deciding.

3CX ENT+ ends in January 2027: what businesses in Luxembourg should check

3CX will move ENT+ licences to AI Edition in January 2027 at no extra cost and will end its own cloud transcription service.

Businesses in Luxembourg and the Greater Region that run 3CX through a local partner should check their licence type before January 2027. The licence change is automatic, but call recording and voicemail transcription will stop unless a new engine is set up. Choosing OpenAI, Google or xAI sends call audio to a third party, so GDPR records and staff information may need an update. The self-hosted 3CX AI Server keeps audio on your own system but needs AI Edition with Update 10.

Mixvoip second in Luxembourg business fixed telephony at 5.2%, behind POST Luxembourg at 79.7%

Using ILR market data, Mixvoip reports that its share of business fixed telephony in Luxembourg went from 4.7% at the end of 2024 to 5.2% at the end of 2025, keeping second place behind POST. Business copper (PSTN) lines dropped from about 18,400 to 6,900, while voice over broadband lines grew from about 26,900 to 33,700.

The ILR figures show how quickly Luxembourg businesses are leaving copper: in one year, business PSTN lines fell by more than half while voice over broadband lines grew. POST still holds about four in five business fixed lines, so the market stays highly concentrated even as alternative operators gain ground. A company still on an analogue or ISDN line can plan its move to SIP or a cloud PBX on its own schedule rather than under time pressure.

POST Telecom extends phone trade-in and longer financing to keep devices in use

POST Luxembourg explains how its telecom business helps customers keep and reuse mobile phones. It runs a trade-in service with partner Recommerce, collects old devices in its shops for repair or recycling, and now offers phone financing over 36 or 48 months. POST plans to sell refurbished phones in its shops by the end of the year and has set targets for 2030.

For Luxembourg companies that equip staff with mobile phones, trade-in and longer financing can lower the upfront cost of a device refresh. A 36 or 48 month plan also means phones stay in use longer, so it is worth checking that the chosen models will keep receiving security updates for that whole period. Refurbished phones in POST shops would give businesses another option when they need extra devices quickly.

Orange Business and NVIDIA pilot voice AI agents spread across cloud and regional sites

Orange Business is working with NVIDIA on voice AI that runs partly in a central cloud and partly at regional network sites. The goal is faster replies from AI call agents and more control over where voice data is processed. A pilot shows calls being translated, transcribed and summarised, and Orange Business plans to add NVIDIA Nemotron models to its Live Intelligence platform.

Where an AI call agent processes voice data is a key question for Luxembourg firms in finance and the public sector, which often must keep data inside the EU. Running part of the AI at regional network sites can also cut the delay that makes AI agents sound slow on a call. Since 2 August 2026, the EU AI Act requires that callers are told when they are speaking to an AI, so businesses should plan that notice into any voice agent they deploy.

STARFACE launches a new generation of on-premises phone system appliances

STARFACE has released new hardware appliances for its on-premises phone system, made in Germany. There are four models for between 25 and 2,000 users, with faster processors, more memory and larger SSDs. They are available now through resellers and come with a 24-month warranty.

Not every business wants its phone system in the cloud, and on-premises appliances remain common in German and Greater Region companies with strict data rules or a preference for keeping hardware in-house. The new models cover anything from a small office to 2,000 users, so they fit both SMEs and larger sites. Buyers in Luxembourg should check that a local reseller supports STARFACE and that their SIP trunk from a Luxembourg operator works with it before choosing on-premises.

Synthflow AI'S Voice Technology Goes Live on Zoom Phone and Zoom Contact Center, Powering Conversational CX at Scale

Berlin-based Synthflow AI now offers AI voice agents for Zoom Phone and Zoom Contact Center, with Batteries Plus as the first large US user.

AI voice agents are moving from separate tools into the phone system itself, which changes how a Luxembourg business can handle routine calls. Since 2 August 2026, the EU AI Act requires that callers are told when they are speaking to an AI system, unless this is obvious. When an agent hands a call to a person with a full transcript, the GDPR also applies to that transcript and where it is stored. The launch is described for the United States only, so European availability and data location should be checked with Zoom or Synthflow.

ACM Telecommonitor second quarter 2026

Dutch regulator ACM reports 3.75 million fibre internet households and 24.77 million mobile connections in the Netherlands for Q2 2026.

The Dutch figures show the same shift Luxembourg businesses face: traditional calling is falling while fibre and data keep growing. In the Netherlands, calls over fixed lines dropped 7.43% in one quarter to 800 million minutes. In Luxembourg, the ILR 2025 report puts fibre at 72.8% of fixed internet access, with about 15,500 analogue lines left and nearly all other lines running on voice over broadband. For companies with sites in both countries, phone service now depends mainly on the quality of the broadband line.

Zoom introduces smarter meetings, seamless workspaces for richer collaboration, and intelligent calling

At Zoomtopia 2026, Zoom announced AI updates for meetings, rooms, chat and Zoom Phone, including SMS and call screening for its virtual receptionist.

For businesses in Luxembourg that use or compare Zoom Phone, the key point is which of the new calling features will work with a Luxembourg number. Zoom's coverage page lists Luxembourg for local numbers, but not for SMS/MMS or toll-free numbers, which matters for the planned SMS replies of the virtual receptionist. Call screening and SMS are due in December 2026, while the WhatsApp Business integration is available now. Meeting connectivity with Microsoft Teams is planned for the first half of 2027.

IP phones – the IT endpoints built to last

A Snom channel manager argues that IP phone buyers should check how long security and firmware updates last, not just the feature list.

For desk phones bought in Luxembourg and the rest of the EU, the support question is now partly settled by law. Under the Cyber Resilience Act, manufacturers have had to report actively exploited vulnerabilities since 11 September 2026, and from 11 December 2027 they must declare a security support period of normally at least five years. The UK rules cited in the article cover consumer devices only, while the EU regime also applies to business phones. When comparing Cloud PBX offers, ask which handset models are supported and until when they receive firmware updates.

Deutsche Telekom deploys AudioCodes VoiceAI Connect for AI call notes

Deutsche Telekom launches an AI service for SMEs that records, transcribes and summarises mobile business calls, using AudioCodes and Mistral AI.

Deutsche Telekom is adding AI call notes on its mobile network, rather than inside a desktop phone system. For businesses in Luxembourg and the German part of the Greater Region, the key question is where recordings and transcripts are processed: here it is Telekom's T Cloud with Mistral AI, a European model provider. Before switching on any call transcription, a company must inform callers and define a legal basis under the GDPR. When comparing Cloud PBX offers, ask whether transcription is included, which AI provider runs it and in which country the data is stored.

Mixvoip Review 2026: Fast & reliable home internet in Luxembourg

LetzCompare reviews Mixvoip's Five home internet range in Luxembourg, from 30 to 2,000 Mbit/s, with prices, router fees and contract terms.

For staff who work from home on a Cloud PBX, the home line also carries business calls, so its terms matter as much as its speed. A voice call needs roughly 100 kbit/s, so even the 30/10 Mbit/s plan has enough upload for calls. The points to check are Mixvoip's residential support window (Monday to Friday, 09:00 to 16:00) and the gap between the five-month plan term and the 24-month default in its general terms. Companies that pay for employees' home connections should check the term in the written quote.

AI Is Making 3CX More Efficient. We're Passing the Savings On.

3CX is lowering prices on new licences from 24 simultaneous calls and adding a three-year discount, saying AI has cut its own costs.

3CX says AI has made its development, testing and support cheaper. It is cutting prices on new licences by 10% from 24 simultaneous calls and by 15% from 256, with an extra 10% for a three-year commitment. Hosting is not included. It is also retiring its own voicemail transcription service in favour of third-party providers, scaling back webinar features and adding a fair use policy. Businesses in Luxembourg and the Greater Region that run 3CX should check how these changes affect their next renewal and the features they use.

Equitix, MDM et Orange créent une coentreprise pour déployer le système de câble sous-marin Pisces, avec le soutien financier de l'Union européenne

Equitix, MDM and Orange have formed a joint venture to build Pisces, an EU-backed subsea cable linking Ireland, France, Spain and Portugal by 2028.

Pisces is a planned subsea cable of about 3,125 km with 16 fibre pairs. It will land at Galway, Saint-Hilaire-de-Riez in France, Sopelana in Spain and Carcavelos in Portugal. The EU's Connecting Europe Facility is helping to fund it, and it gives Ireland a direct route to continental Europe that does not pass through the UK. For businesses in Luxembourg and the Greater Region, more diverse international routes into France add resilience for cloud and data centre traffic over time. Deployment is planned for 2028.

Proximus NXT: Data & Cloud: pourquoi ne plus les penser séparément

Two Proximus NXT experts argue that companies should plan cloud, data and AI as one platform, with data sorted by sensitivity and access rights kept current.

For Luxembourg companies, phone data is often a separate silo: call logs, recordings and voicemails sit in the Cloud PBX, apart from the CRM and Microsoft 365 data that AI tools are meant to search. Before adding AI call summaries or a voice assistant, check who can open recordings today and close the extensions and voicemail boxes of staff who have left. It also helps to ask the provider whether call history can be exported or synced to the CRM in a standard format, so it does not stay locked in one system.

Bouygues Telecom and iBASIS sign long-term, strategic partnership for International Voice, IPX, Wholesale Roaming Services and jointly launch Roaming Office.

Bouygues Telecom hands its international voice, IPX and roaming operations to iBASIS, and the two firms launch a shared Roaming Office.

Under a long-term deal, iBASIS gets exclusive rights to Bouygues Telecom's international voice wholesale and IPX traffic. It also takes over Bouygues Telecom's roaming negotiations and daily roaming operations. Together they created Roaming Office, which aims to give independent operators more scale when they negotiate roaming terms. iBASIS says Bouygues Telecom is the eighth large operator to hand it international wholesale, as operators move to VoLTE and 5G standalone. Roaming quality for people travelling between France and Luxembourg depends on deals like this one, even though users never see them.

Colt expands global network investment to power the next wave of AI growth

Colt is extending its network for AI traffic, with new metro networks in Berlin, Frankfurt and Bordeaux and new routes in Africa, Asia and the Middle East.

Colt is adding capacity in North America, Africa, Asia and the Middle East, including a new site in Johannesburg and a fibre route of more than 600 km between Osaka and Fukuoka in Japan. In Europe, it is building new metro networks in Warsaw, Bordeaux, Zaragoza, Berlin and Frankfurt, which brings its total to 55, and upgrading the fibre route between Marseille and Milan. Frankfurt is a key interconnection hub for many Luxembourg networks, so more capacity there is relevant for Greater Region firms that run cloud and AI workloads. The announcement does not give an investment amount.

Odoo Awards Winners 2026

Odoo named its 2026 award winners at Odoo Experience in Brussels, with Spanish integrator Studio73 taking the Best Partner Europe title.

Odoo closed its 2026 Experience event in Brussels with its yearly partner awards, and Studio73 from Spain was named Best Partner Europe. For Luxembourg businesses the ERP is increasingly linked to the phone system: Mixvoip, one of the providers listed on pbx.lu, is a Gold Sponsor of the Odoo Community Association and offers a Voxbi Cloud PBX integration that places and logs calls directly inside Odoo. When choosing a PBX, it is worth checking how deeply it connects to the ERP the company already runs.

Mixvoip cybersecurity lead Patrick Berg talks about SME security risks in Paperjam interview

Patrick Berg, who leads cybersecurity at Mixvoip, gave a video interview to Paperjam about the security problems small and medium companies face. He says attackers use automated tools and often see smaller firms as easy targets. He also says that stress and weak crisis planning during an attack can cause more harm than the technical damage.

Luxembourg SMEs are frequent targets because automated attacks scan for weak points regardless of company size. For phone systems, common risks include stolen SIP credentials used to run up international call charges and fake calls that pretend to come from managers or suppliers. A short written plan that says who to call and which accounts to lock during an incident can limit the damage, whichever provider a company uses.

New SecNumCloud qualification: Orange Business expands its trusted cloud portfolio for critical applications and AI

ANSSI qualifies new Orange Business Cloud Avenue environments under SecNumCloud, with dedicated resources in two French data centres for critical apps and AI.

France's cybersecurity agency ANSSI has granted SecNumCloud qualification to new Cloud Avenue infrastructure environments from Orange Business, adding to a first qualification in July 2025. Resources are dedicated to each customer and run across two data centres in Val-de-Reuil and Chartres, with GPU servers available for AI training and inference. The announcement concerns the French group offer rather than Luxembourg, but SecNumCloud is one of the labels buyers cite when comparing sovereign cloud offers, so it is relevant for Greater Region organisations with French operations or French public-sector clients.

Sovereign S3 Is Not A Postcode: Seven Questions Buyers Must Ask

A buyer checklist for sovereign S3 storage: who owns the provider, who holds the keys, where control and backups sit, exit costs and written proof.

The piece argues that a Luxembourg or EU address is not enough to call S3 object storage sovereign, and lists seven checks: ownership up the chain, control of encryption keys, location of the control plane, where replicas and backups sit, real S3 feature support such as Object Lock, the cost of leaving, and what the provider will commit to in writing. For regulated Luxembourg firms under DORA, NIS2 and CSSF rules, these questions turn a marketing label into something that can be checked in a contract. The same logic applies to any hosted service that stores business data, including call recordings in a cloud phone system.

3CX releases Windows Softphone V5.8 with single sign-on and outbound number choice

3CX has released version 5.8 of its softphone app for Windows. Users can now sign in with Google, Microsoft 365 or email, choose which of their numbers to call from, and set a default transfer method for BLF keys. The new features need the phone system to run V20 Update 10.

For Luxembourg companies that run 3CX, the new Windows softphone mainly helps staff who work from home or across borders. Signing in with Microsoft 365 or Google removes a separate password, and choosing the outgoing number lets one person call clients from a Luxembourg, Belgian or French number as needed. Admins should confirm the phone system runs V20 Update 10 before rolling out the update.

Wildix receives ISO 27001, 27017 and 27018 certifications for security and cloud privacy

Wildix says it is now certified to three ISO standards: 27001 for information security management, 27017 for cloud security and 27018 for protecting personal data in the cloud. The company says an outside auditor checked its systems. The certificates are published on the Wildix Trust Center.

ISO 27001, 27017 and 27018 are among the certificates that Luxembourg buyers in finance and the public sector often ask for when they assess a cloud phone provider. Under DORA, financial companies must also assess the security of their ICT suppliers, so published certificates make that check easier. A certificate covers the provider's own systems, so buyers should still ask where call data and recordings are hosted.

Colt launches managed SCION network service for secure enterprise connections

Colt Technology Services now offers a managed service based on SCION, a network technology developed in Switzerland by Anapaya. It comes in two versions: one for private links between partners, such as banks, and one for building secure company backbone networks. Colt says customers can control and check the path their data takes, which helps with compliance and data sovereignty.

SCION lets a company choose and verify the path its data takes across networks, which matters to Luxembourg banks and fund companies that must show where sensitive traffic travels. The Swiss financial sector already uses SCION for its interbank network, so groups with offices in both Luxembourg and Switzerland may meet it first. For most SMEs it is not yet a phone system decision, but it shows where secure business connectivity is heading.

Deploy Vendor Firmware Directly From 3CX

3CX V20 Update 10 lets admins upload phone makers' firmware and roll it out to supported IP phones from the PBX.

With V20 Update 10, 3CX adds a firmware library where admins can keep both 3CX-validated and vendor firmware, set a preferred version per phone model, and override it for single devices. Assigning new firmware reprovisions and may reboot phones, so changes should be scheduled outside business hours. For Luxembourg IT teams managing desk phones across several sites, central firmware control makes staged rollouts and troubleshooting easier.

Frost & Sullivan lists Wildix as an Innovator in its 2026 cloud communications report

Wildix was placed in the Innovators group of the 2026 Frost Radar for integrated cloud communications platforms, which looked at 19 vendors. The report looked at how vendors combine phone, contact centre and messaging tools with AI. Frost & Sullivan pointed to Wildix's Wilma AI assistant, its flexible deployment options and its partner-based sales model.

Analyst reports such as the Frost Radar help build a first shortlist, but they rank vendors globally and say little about local support or Luxembourg numbers. Wildix sells through partners, so for a Luxembourg or Greater Region business the quality of the local reseller matters as much as the platform. Buyers comparing cloud phone systems should ask who handles installation, support and number porting locally.

Colt joins European Space Agency consortium to advance autonomous network resilience across fibre and satellite

Colt, neXat and Telesat start an ESA-backed project to detect subsea cable cuts and reroute priority traffic over satellite.

The CableShield project, funded with €1.5 million under ESA's ARTES programme, aims to spot major submarine cable failures automatically and move priority traffic onto low Earth orbit satellite links. The 18-month programme will test the idea in the lab and in the field before any commercial decision. For a landlocked hub like Luxembourg, which depends on cross-border fibre routes, work on automatic failover between fibre and satellite is relevant to long-term network resilience.

Orange Business chosen to build the EU's secure TESTA-EIRIS backbone network

Orange Business has been selected to build TESTA-EIRIS, a private and isolated network that public administrations in EU member states use to exchange data. It will work with the European Commission's IT department (DG DIGIT). The network will link at least 12 sites in five European regions, with network and security monitoring centres.

TESTA is the private network that EU institutions and national administrations use to exchange sensitive data, and Luxembourg is home to several EU institutions. The contract shows how much weight public buyers now give to isolated, monitored networks instead of the public internet. Luxembourg companies that supply public bodies can expect similar requirements on private links, security monitoring and data location to appear in tenders.

Colt announces connectivity to Oracle EU Sovereign Cloud via OCI FastConnect

Colt now offers private links to Oracle EU Sovereign Cloud in Frankfurt and Madrid, keeping traffic off the public internet.

Colt will connect enterprises privately to Oracle's EU Sovereign Cloud regions in Frankfurt and Madrid through OCI FastConnect, rather than over the public internet. Using two regions also supports business continuity and disaster recovery designs. For Luxembourg and Greater Region firms that host regulated workloads in a sovereign cloud, the network path to that cloud is part of the sovereignty and resilience question, not only the data center location.

Mit SIP-Trunks von Gamma und STARFACE zur resilienten Business-Telefonie

Gamma and STARFACE launch a migration offer pairing STARFACE phone systems with Gamma or STARFACE SIP trunks from one provider.

Gamma Channelhouse is offering a combined package: a STARFACE phone system plus either the Gamma NGN Connect trunk, which adds backup routing and encryption, or STARFACE Connect for close PBX integration on-premise or in the cloud. Network, operations and support come from Germany, with a four-step switchover planned without interrupting calls. For Greater Region businesses, one contract for PBX and SIP trunk simplifies who is responsible when calls fail, though it also concentrates dependence on a single provider.

Your phone system is becoming part of your AI governance strategy

Mixvoip explains why AI features in phone systems now fall under EU AI Act governance and compliance requirements.

As AI features spread through business phone systems, from call transcription to sentiment analytics, they fall under the EU AI Act like any other AI deployment. For Luxembourg and Greater Region companies, that means knowing which AI functions are actually running inside their communications stack, and who is responsible for them, the provider or the business itself. Providers that can map their AI features against a clear governance and compliance picture make that assessment easier for customers navigating the AI Act's phased requirements.

https://thedots.lu/news/show/your-phone-system-is-becoming-part-of-your-ai-governance-strategy

AI is moving into the business phone system. Companies should know exactly where.

ITnation looks at how AI features in phone systems need clear technical and policy controls to meet EU AI Act rules.

Business phone systems are picking up AI capabilities such as transcription, call summaries and conversation intelligence, and each of these carries a different level of regulatory risk under the EU AI Act. A summary tool and a system that scores employee performance are not the same category of risk, so a single AI policy for everything is not enough. For Luxembourg and Greater Region businesses adopting these tools, the practical requirement is technical controls and clear user permissions alongside the legal paperwork, not a policy document on its own.

Secure, Data-Sovereign AI Translation for Public Authorities and SMEs

innovaphone adds the EU's eTranslation service to myApps, giving public bodies and SMEs AI translation run on Commission infrastructure.

innovaphone has integrated eTranslation, the European Commission's AI translation service, into the Translations and Connect apps of its myApps platform. Processing stays inside Commission infrastructure, all 24 official EU languages are covered, and eligible public bodies and SMEs can use it free after registering. For multilingual Luxembourg, where daily work mixes French, German and English, built-in translation with a clear data location is a practical feature.

STARFACE Gründer Florian Buzin zieht sich zum Jahresende zurück

STARFACE founder Florian Buzin leaves at the end of 2026, with a five-person team already running the Gamma-owned group.

Florian Buzin co-founded STARFACE in 2005 and has led it for more than 21 years. He steps down at the end of 2026, while a five-person leadership team that has run the group since mid-2025 stays in place. STARFACE merged with Gamma Communications in early 2025 and now sits alongside estos in the Gamma Group, and the company says customers and partners in Germany and the Greater Region will see no changes.

Wildix Recognized in 2026 Gartner® Magic Quadrant™ for Unified Communications as a Service

Wildix says it is listed as a Niche Player in Gartner's 2026 UCaaS Magic Quadrant, its sixth year in the report.

According to Wildix, the 2026 Gartner Magic Quadrant for UCaaS places the company in the Niche Players segment for a sixth year in a row, and it describes itself as the only European vendor in the report. These claims come from the vendor's own release rather than the Gartner text. For buyers in Luxembourg and the Greater Region, analyst reports are one input among several, next to local support, data location and integration with existing tools.

Wildix Deploys Wilma AI as Mandatory L1 Technical Support, Resolving Nearly Half of Requests Instantly and Without Human Intervention

Wildix makes its Wilma AI the first support line for partners and says it solved 46% of 1,273 requests without an engineer.

Since 8 June, Wildix partners must go through the Wilma AI assistant for first-level technical support, replacing web ticketing. Over about two months, Wildix reports that 46% of requests were closed without an engineer and 40% reached human teams with context already collected. For Luxembourg businesses buying UCaaS through a reseller, this kind of change affects how fast their partner can escalate an issue to the vendor, which is worth checking in support terms.

Record net result in 2025 enables LuxConnect to accelerate investments in digital and sustainable infrastructure

LuxConnect posts a record 2025 profit and reinvests it in data center and AI infrastructure projects in Luxembourg.

LuxConnect closed 2025 with a record net profit, giving it more room to invest in digital infrastructure, including preparing its Bissen site for the MeluXina supercomputer and Luxembourg's AI Factory. For the Greater Region, this kind of reinvestment in local data center and connectivity capacity feeds directly into the infrastructure that underpins cloud PBX and other hosted communications services. It is also a useful data point on the broader financial health of Luxembourg's digital infrastructure sector.

Telkea presents its offer for Luxembourg care homes, from nurse call systems to care software hosted in its local private cloud.

Telkea, which started in 1929 as a Luxembourg telephony company, now groups ICT, security, telecom and software units. For care homes it combines nurse call and alert tools with the GestoCare care software, using role-based access, encryption and the option to host in its Luxembourg private cloud. It shows how communications in healthcare now go well beyond the phone line, and why data location and access control matter in care settings.

Luxembourg Tech Firms Launch AI-Powered Call-Handling Solution

Mixvoip and Luxembourg startup Elora launch an AI call agent that answers calls, takes messages and creates tickets over SIP.

Missed calls during peak times or after hours are a common pain point for smaller businesses in Luxembourg and the Greater Region. AI call agents that connect over SIP to a cloud PBX can answer, qualify and route calls or take structured messages in several languages. This partnership reflects a wider trend of pairing conversational AI with business telephony to keep every enquiry covered.

AI Sovereignty Emerges as a Strategic Imperative for Luxembourg Organisations

At a Golden-I Masterclass, Proximus NXT finds data leakage is Luxembourg leaders' top AI sovereignty concern.

At a Golden-I Masterclass, Proximus NXT highlighted that while most Luxembourg organisations have already approved some generative AI tools for staff, many still cannot say exactly where that data travels once it leaves their systems. Data leakage came out as the top concern among the technology leaders in the room, ahead of other AI adoption risks. The session's central point for Greater Region businesses: sovereignty is not just an infrastructure choice, it needs an ongoing governance framework to actually hold up in practice.

Partenariat entre Mixvoip et Elora

Mixvoip and Elora partner to add conversational AI receptionists to Cloud PBX, answering and routing inbound calls around the clock through native SIP.

This partnership pairs a Luxembourg telecom provider's Cloud PBX with conversational AI so inbound calls can be answered, qualified and routed automatically, even outside office hours. For smaller Luxembourg and Greater Region businesses, missed calls are lost opportunities, and an AI answering layer bolted onto an existing phone system offers a way to stay reachable without adding staff. Because the calls stay inside a SIP-integrated European platform, data handling remains subject to EU privacy rules.

cegecom complète son écosystème « Made in Luxembourg » avec F3C Systems

Cegecom, Luxcontrol and F3C Systems combine to offer Luxembourg SMEs a full-cycle cybersecurity service.

Cegecom has partnered with F3C Systems, alongside Luxcontrol, to build a full-cycle cybersecurity offering for Luxembourg companies: governance and compliance from Luxcontrol, secure connectivity from cegecom, and a 24/7 security operations centre from F3C Systems. Rather than businesses buying separate security tools, the three local firms package this as one offering, with pricing based on the number of assets monitored rather than data volume. For Greater Region SMEs, it is a concrete example of local providers combining to make enterprise-grade security more accessible and easier to budget for.

Mixvoip Cyber Suite : assistance opérationnelle et assurance

Mixvoip and Foyer partner Equidem launch a Luxembourg offering combining emergency cyber-assistance with professional cyber-insurance for businesses.

Mixvoip has teamed up with insurer Foyer, through Equidem, to launch the Mixvoip Cyber Suite, presented as Luxembourg's first offer to combine operational cyber-assistance with professional cyber-insurance. It pairs a round-the-clock emergency hotline and on-site response with cover for the financial costs that follow an incident. For Luxembourg businesses and public bodies facing rising attack volumes, bundling fast technical response and insurance in one contract narrows the gap between detecting a breach and paying to recover from it.

FreeSWITCH 1.11 released

FreeSWITCH 1.11 brings security and stability fixes, Debian 13 support and the removal of around 30 legacy modules.

FreeSWITCH is the open-source voice engine behind many hosted and on-premise phone systems, including FusionPBX. Version 1.11 focuses on security fixes, moves to a newer regular expression library and drops about 30 older modules, so admins should check that nothing they rely on was removed before upgrading. For businesses in Luxembourg and the Greater Region that run self-hosted telephony, keeping the voice engine patched is a basic part of call security.

Proximus NXT Luxembourg accelerates cloud sovereignty with Microsoft through Azure Local Disconnected Operations

Proximus NXT adds Microsoft's disconnected Azure Local operations to its Luxembourg sovereign cloud offering.

Proximus NXT Luxembourg has added Microsoft's Azure Local Disconnected Operations to its sovereign cloud portfolio, letting organizations keep workloads running locally without a constant link back to the public cloud. For regulated businesses in Luxembourg and the Greater Region, that kind of local control over where data sits and how it is processed is becoming a standard requirement alongside cost and performance. It also reflects a wider trend among cloud and communications providers serving the region: building sovereignty options directly into infrastructure rather than treating it as an add-on.

Eltrona and its CEO Bart D'Olieslager agreed to part ways, and board member Gerald Demortier takes over on an interim basis from 1 June 2026. Eltrona, Luxembourg's historic cable operator with more than 50,000 customers, has been owned by Belgium's Telenet since 2023. The company says the change is meant to keep operations stable for customers and partners, while leadership shifts at a major local operator are worth tracking for future product direction.

Rethinking Collaboration. Made in Europe.

innovaphone turns its myApps UC platform into UCC, adding a Connect collaboration hub, a choice of AI model and new IP phones.

innovaphone is moving its myApps platform from unified communications to UCC, with the Connect app as a hub for documents, surveys and AI meeting minutes, and a single UCC licence replacing the old UC licence. Customers can pick the language model used for AI features and run the platform on-premise, which the German vendor presents as a data sovereignty choice. For Greater Region organisations comparing European UC platforms, licensing changes like this are worth checking against existing contracts.

Proximus NXT has been picked as one of four suppliers on a six-year framework to provide sovereign cloud services to EU institutions, covering bodies from the European Commission to more than 70 agencies. The award underlines how sovereignty, meaning European-controlled infrastructure and reduced dependence on non-European providers, has become a formal procurement criterion rather than just a marketing angle. For Luxembourg, a hub for both telecom and EU institutional business, contracts like this reinforce the country's position in the European sovereign cloud market.

Bien intégrer l'IA au cœur des processus métiers

Proximus NXT on why embedding AI in business processes raises sovereignty and governance questions, not just technical ones.

Proximus NXT argues that organisations are moving from experimenting with AI to embedding it in core business processes, and that this shift raises real questions about data sovereignty, infrastructure choices and integration with existing systems. Rather than one general-purpose model, the piece points to specialised AI agents working together and connecting to a company's own data as the more practical pattern. For Luxembourg and Greater Region businesses, the underlying message is that governance and a clear link to business outcomes matter as much as the AI technology itself.

Microsoft Teams: betting on direct routing

Microsoft Teams

Mixvoip makes the case for Microsoft Teams direct routing over operator connect, citing greater control over infrastructure, routing and resilience.

As Microsoft Teams becomes the default workplace hub for many Luxembourg businesses, how voice calling is wired into it becomes a real architectural decision. Direct routing keeps call routing, redundancy and data location under the organisation's own control, while operator connect centralises setup inside Teams but still ties billing and contracts to an operator. For firms bound by European compliance rules, understanding that trade-off matters before committing a phone system to Teams.

https://en.paperjam.lu/article/microsoft-teams-betting-on-direct-routing

Microsoft Teams In 2026: Why Direct Routing Is The Smart Choice

Microsoft Teams

Mixvoip's Patrick Berg argues that Direct Routing gives businesses more control over Microsoft Teams telephony than Operator Connect.

Connecting Microsoft Teams to the public phone network can be done through Operator Connect or Direct Routing, and the choice shapes how much control a business keeps over its call routing and infrastructure. For companies in Luxembourg and the Greater Region, Direct Routing keeps telephony architecture, data location, and redundancy strategy in the operator's hands rather than fixed to a predefined model. That control matters most where regulatory compliance and call resilience are non-negotiable, such as regulated finance and public-sector work. Pairing Teams with a second network path or mobile failover keeps communication running when a single link goes down.

It is open to Luxembourg-based micro-enterprises and SMEs regardless of how far along they already are digitally. For the Greater Region's SME base, having a single structured entry point for digital transformation, rather than sourcing telecom, cloud and security separately, lowers the barrier to getting started.

From challenger to leader 2026

Mixvoip reports it has grown into Luxembourg's second largest fixed-line telephony provider, built on business VoIP, SIP and managed Teams direct routing.

This is Mixvoip's own account of moving from challenger to Luxembourg's second largest fixed-line telephony provider, now handling over ten percent of national fixed-line traffic once wholesale is included. It reflects a wider shift across the Greater Region toward independent operators that control their own infrastructure rather than reselling legacy networks. For business readers, it is a useful signal that alternatives to the historical incumbents have reached real operational scale.

Microsoft Teams telephony in 2026: Mixvoip enables Direct Routing in under 15 minutes

Microsoft Teams

Mixvoip says its fully managed Direct Routing service can connect Microsoft Teams to the public phone network in under 15 minutes.

Many Luxembourg organisations run on Microsoft Teams and want to use it for external calls without building their own voice infrastructure. Managed Direct Routing hides the session border controller and routing behind the operator, so IT teams only handle user setup inside Teams. Fast activation and clear operational ownership are key criteria when businesses choose how to add PSTN calling to Teams.

Cegecom launches Operator Connect in Luxembourg

Microsoft Teams

Cegecom becomes the first Luxembourg operator to offer Microsoft Teams Operator Connect, adding certified Teams calling with local numbers.

Operator Connect lets a local carrier plug certified voice services directly into Microsoft Teams, so businesses can keep Luxembourg numbers while calling from the Teams app they already use. Cegecom being first to market signals that Teams-based telephony is becoming a mainstream option for Luxembourg companies alongside traditional PBX and SIP. For decision-makers, the choice now often comes down to how a provider handles number portability, call quality, and local support rather than the underlying technology.

Microsoft Teams Direct Routing vs Operator Connect in 2026

Microsoft Teams

Mixvoip compares Microsoft Teams Direct Routing and Operator Connect, arguing Direct Routing offers more flexibility and cost control.

Choosing how to connect Microsoft Teams to the phone network is a practical decision for Luxembourg IT buyers weighing flexibility against simplicity. Direct Routing gives more control over routing, carriers and cost, while Operator Connect centralises number management inside the Teams admin center. Knowing that both still require Microsoft licences and a telecom contract helps businesses compare real total cost rather than surface-level convenience.

Mixvoip expands its Microsoft Teams telephony services, using Direct Routing and certified SBCs to turn Teams into a full business phone system.

Mixvoip is positioning itself as an integration partner for Microsoft Teams telephony, linking Teams to the public phone network through certified session border controllers and Direct Routing. The approach lets organisations keep legacy SIP devices such as door phones and intercoms, and port numbers across more than 25 countries. For companies in Luxembourg and Belgium standardising on Teams, having a local operator handle the telecom side can simplify a project that often stretches internal IT teams.

Microsoft Teams

Cegecom is the first local operator to bring Microsoft Teams Operator Connect to Luxembourg, adding certified calling with Luxembourg numbers directly inside Teams.

Operator Connect lets organisations turn Microsoft Teams into their business phone system using a certified carrier, without extra hardware to run. A local operator offering it means Luxembourg numbers and in-country support for firms standardising on Teams for calls. The move fits a broader shift away from on-site PBX equipment toward cloud and Teams-native voice across the Greater Region.

Integrating a phone system directly with an ERP like Odoo lets Luxembourg businesses tie every call to the right customer record and automate follow-up. For sales and support teams in the Greater Region, that context can cut manual data entry and speed up response times. Native SIP integration and AI call summaries are becoming standard expectations when companies evaluate a cloud PBX.

Voxbi 2 is a cloud phone platform developed and hosted in Luxembourg, aimed at regulated firms that need communications data to stay in-country. Features such as MiFID II-compliant recording, single sign-on and fixed-mobile convergence speak to a market shaped by compliance rules and cross-border commuting. For local businesses, sovereign hosting is becoming a practical selection criterion for a phone system rather than just a talking point.

Post Luxembourg blames “technical incident” for network outage

Post Luxembourg attributes a nationwide network outage to a technical incident affecting fixed and mobile services.

A national outage on the incumbent's fixed and mobile network interrupted services for businesses across Luxembourg, and for a time cut access to emergency numbers. Incidents like this are why resilience features, such as automatic failover to a second network or to mobile, matter when choosing a phone system. Providers that layer over more than one backbone can keep calls running when a single operator's network fails.

Mixvoip acquires Crossing Telecom's customers

Mixvoip has taken over Crossing Telecom's business customer base, its largest deal yet, reinforcing its number-two position in Luxembourg fixed telephony.

The deal moves around 450 Luxembourg SMEs onto a larger local operator, with existing contracts and support staff carried over to limit disruption. Consolidation like this is steadily reducing the number of independent fixed-line providers serving businesses in the country. For companies, the practical questions during any such transfer are service continuity, contract terms and who to call when something breaks.

The pitch centres on data governance and treating AI as a tool that supports staff rather than replaces them. For Greater Region businesses weighing generative AI adoption, it is one more sign that data residency and vendor choice are becoming as important as the AI features themselves.

The move packages together AI, cloud sovereignty and cybersecurity services under one name, while keeping the underlying 110-person French team and existing client base intact. For Luxembourg and Greater Region readers, it is a useful marker of how POST Group is consolidating its digital services under a single brand rather than a set of separate acquisitions.

DEEP, part of POST Group, and OVHcloud have formalised a partnership to run sovereign cloud infrastructure in Luxembourg, giving local enterprises a locally hosted alternative for sensitive data and workloads. The deal reflects a pattern also visible in more recent sovereign cloud moves from Proximus NXT: Luxembourg-based operators pairing with larger cloud vendors to offer data residency and protection from extraterritorial access. For the Greater Region, it adds another concrete option to the growing list of sovereign cloud providers active in the local market.

Dating from 2007, this agreement made Cegecom the main fixed-telephony partner for Crossing Telecom, carrying its customers' calls off the historic operator's network. It reflects an early phase of competition among alternative operators that still shapes business telephony in Luxembourg. Seen next to more recent changes around Crossing Telecom, it shows how customer bases in this market pass between providers over time.
