📞 Wildix is a European UCaaS vendor founded in 2005, headquartered in Estonia with R&D teams in Ukraine and Italy. It provides a cloud phone system built natively on WebRTC, meaning users can make and receive calls from any browser without installing a VPN or a dedicated client. Wildix is distributed exclusively through certified reseller partners and is not available to buy directly.
Who is Wildix?
Wildix is not a telecom operator. It is a software vendor that builds a cloud phone system designed primarily for sales-oriented teams. Its main platform, Collaboration, runs in the browser using WebRTC technology: voice, video, and team messaging all work from a standard web browser, without a separate application or VPN.
The company was founded in 2005 and is registered in Estonia. Its development teams are based in Italy and Ukraine. Wildix reached a notable milestone in 2024 when Gartner recognized it as a Niche Player in the UCaaS Magic Quadrant, the first European-headquartered vendor to appear in that ranking.
Wildix is sold entirely through a network of certified reseller partners. There is no direct sales channel. Pricing is set by each partner and is not published publicly.
Who uses Wildix?
Wildix targets sales-driven organizations with 20 to 500 employees. Its feature set is built around lead capture, CRM integration, and AI-assisted conversations rather than general office telephony.
Sales teams and commercial SMEs are the primary target. Wildix's website chat widget (Kite) connects website visitors directly to agents via WebRTC. Its AI product (Wilma) provides voicebot automation, meeting summaries, and real-time conversation suggestions for agents.
Tech-forward businesses appreciate the browser-native approach: no hardware provisioning, no VPN, no separate client installation. Any device with a browser and a headset becomes a workstation.
Organizations already using Salesforce, HubSpot, or Microsoft Teams benefit from Wildix's 250+ CRM and app integrations.
Wildix is less suited to businesses that need local Luxembourg support, transparent pricing, or a single provider for both numbers and PBX.

Detailed comparison
🏗 Platform and architecture
Wildix is built on WebRTC from the ground up. A user opens the Collaboration app in a browser, logs in, and has access to voice, video, messaging, and presence. No softphone client to install, no VPN required, no firewall ports to open for SIP.
The system runs on dedicated single-tenant AWS instances. Each customer has their own isolated environment rather than sharing a multi-tenant platform. This adds a layer of security but means Wildix infrastructure runs on AWS servers, not in Luxembourg data centers.
Voxbi runs on infrastructure operated by Mixvoip in Luxembourg. The two architectures differ in approach: Wildix prioritizes browser accessibility and isolation; Voxbi prioritizes local presence and all-in-one simplicity.
💶 Pricing
Wildix does not publish pricing. Costs vary by reseller partner and depend on plan tier, contract length (monthly, annual, or 5-year), and whether CLASSOUND telephony is included.
The three plan tiers are: Essential (basic PBX), Business (collaboration apps and CRM integrations), and Premium (AI features, contact center, advanced analytics). As a rough reference, independent sources place pricing between approximately 10 and 100 USD per user per month, but the actual cost in Luxembourg depends entirely on the reseller.
Voxbi publishes its pricing at voxbi.com. You can compare before speaking to anyone.
📋 Features: what Wildix includes
Core features confirmed across plans: auto-attendant and IVR, call recording, call queues and ACD, voicemail, browser-based softphone via WebRTC, mobile app (Collaboration 7), video conferencing, team messaging and presence, Active Directory and SSO support, MS Teams integration, and call analytics (advanced analytics on Premium tier).
Business and Premium tier additions: 250+ CRM and app integrations (Salesforce, HubSpot, Zoho, and others), Kite (website chat widget connecting visitors to agents via WebRTC), x-bees (sales acceleration platform), and Wilma AI (voicebot automation, meeting transcription and summaries, real-time agent suggestions).
CLASSOUND is Wildix's optional SIP trunk add-on with bundled call minutes. Without CLASSOUND, you need to bring your own SIP trunk provider. Mixvoip is a certified Wildix SIP trunk provider and can supply Luxembourg numbers for a Wildix deployment.
🔐 Security and infrastructure
Each Wildix customer runs on a dedicated single-tenant AWS instance: no shared database, no shared resources with other companies. This is a stronger isolation model than most multi-tenant Cloud PBX platforms.
The trade-off is geography. Wildix infrastructure runs on AWS, not in Luxembourg data centers. Wildix does not publish the specific AWS region used for Luxembourg-area deployments.
Organizations in regulated industries (banking, insurance, public sector) operating under GDPR or Luxembourg-specific data handling rules should request written confirmation of data residency from their Wildix reseller before committing.
Wildix holds a 99.99% SLA uptime commitment.
🌍 Luxembourg and the Greater Region
Wildix has no office in Luxembourg and does not hold an ILR authorization as an operator. To use Wildix in Luxembourg with local phone numbers, you need a separate SIP trunk provider. Mixvoip is a certified Wildix SIP trunk provider and can supply Luxembourg, Belgian, German, and French numbers.
This creates a two-vendor relationship: Wildix for the PBX platform, Mixvoip for the numbers and lines. For some organizations this is a natural split. For others, managing a single provider for both is simpler.
Voxbi combines the PBX platform and phone numbers from Mixvoip in one package.
🔄 Switching to or from Wildix
Moving to Wildix requires engaging a certified reseller. There is no self-service signup. The reseller handles setup, number porting, and configuration. Timeline depends on the partner.
Moving away from Wildix follows standard number portability rules. In Luxembourg, the ILR regulates number porting, and your existing numbers can be transferred to a new SIP provider within a regulated timeframe. If you use CLASSOUND for SIP, the number porting process runs through your Wildix reseller.
Wildix desk phones use standard SIP protocols and may be reprovisionable for other platforms depending on the model. Standard SIP phones from Yealink, Snom, or Poly provision easily on any Cloud PBX.
