🏢 Who Luxembourg Online is
Luxembourg Online S.A. is one of Luxembourg's oldest telecom operators, founded in 1995. It owns and operates its own DSL and fibre network across more than 150 sites in the country, and reports over 30,000 residential and business customers. The company is 100% privately and locally owned.
Alongside internet, mobile, and IPTV, Luxembourg Online sells business telephony. Its main product is LOLCLOUD Phone, a hosted phone system with call forwarding, multi-site numbering, and mobile and desktop apps. It also offers SIP trunking, a way to connect an existing phone system to the internet, for businesses that run their own IP PBX.
Luxembourg Online serves both residential and business customers. Its strongest market position is in fixed telephony connections, where it ranks third nationally, well ahead of its marginal share of the business internet market.

☁️ LOLCLOUD Phone

👥 Typical client profiles
Based on Luxembourg Online's product focus and contract model.
🏠 Small offices and micro-businesses
Businesses that want one local supplier for internet, mobile, and a basic phone system on a single bill, without managing several vendors.
💶 Cost-led buyers
Buyers who value a low headline seat price and are comfortable with a 24 to 36-month contract in exchange for that price.
🔌 Existing Luxembourg Online customers
Businesses already taking Luxembourg Online internet or mobile that add LOLCLOUD Phone as a simple extra line item on the same bill.
🧑💻 Technical buyers with their own IP PBX
Businesses that run their own phone system and only need a local SIP trunk to carry calls, without a hosted platform.
🎯 Where Luxembourg Online stands apart
Three positioning points that the comparison table above does not fully capture.
🏗️ Owns its own national network
Luxembourg Online operates its own DSL and fibre network across more than 150 sites, so connectivity and phone can sit on one infrastructure and one bill. Few local providers own this much of the physical network themselves.
🕰️ Long local track record
Founded in 1995 and 100% privately and locally owned, with more than 30,000 customers. This history carries weight with conservative Luxembourg buyers who prioritise supplier stability.
💶 Low entry price for simple needs
LOLCLOUD Phone's promotional seat price is one of the lower headline figures in the local market, which makes it a reasonable fit for very small businesses with basic calling needs.

❓ Common questions
Does Luxembourg Online offer a Cloud PBX or business phone system?

Does Luxembourg Online offer SIP trunking?
Yes. Luxembourg Online offers a SIP trunking product for businesses that already run their own IP PBX and want to keep their existing exchange, phones, and numbers. Pricing is available on request.
Can I use Luxembourg Online internet with a different Cloud PBX?
Yes. A Cloud PBX runs over any standard broadband connection. You can use Luxembourg Online for internet access and a separate provider such as Voxbi for your phone system. The two services do not need to come from the same company.
Is Luxembourg Online regulated by the ILR?
Luxembourg Online holds an A-license and publishes a Reference Interconnect Offer, both signs of an authorised operator. According to the ILR's 2025 statistics, it holds 7.9% of fixed telephony connections nationally, ranking third behind POST and Proximus/Tango. Its exact current listing for voice services should be checked directly with the ILR.
Does Luxembourg Online support Microsoft Teams calling?
No Microsoft Teams Direct Routing or Operator Connect offer is listed on the Luxembourg Online site. Businesses that need native Teams calling should confirm this directly with Luxembourg Online or consider a provider such as Voxbi that publishes this feature.
What is the difference between Luxembourg Online's phone system and a specialist Cloud PBX?
Luxembourg Online's LOLCLOUD Phone covers core calling features and is sold as part of a connectivity bundle. A specialist Cloud PBX provider typically documents deeper features such as call queues, reporting, call recording, and Microsoft Teams calling, and does not require a bundled internet contract.
