Mixvoip reinforces its Microsoft Teams telephony expertise in Luxembourg and Belgium

LUXEMBOURG - Dec. 21, 2025 - PRLog -- Mixvoip, a leading telecommunications and IT provider headquartered in Luxembourg, reinforces its expertise in Microsoft Teams telephony by offering advanced Direct Routing integration combined with expert consulting and fully managed services. This approach enables organisations to use Microsoft Teams as a complete business phone system while avoiding the operational complexity traditionally associated with enterprise telephony.

Through Microsoft Direct Routing, Mixvoip connects Microsoft Teams to the public switched telephone network (PSTN) using certified Session Border Controllers (SBCs). This allows users to make and receive external calls directly from the Teams interface, delivering a seamless and secure calling experience for office-based, remote, and hybrid workforces.

Beyond basic connectivity, Mixvoip positions itself as a telephony integration partner rather than a simple telecom operator. The company relies on Microsoft-certified Office 365 and Microsoft Teams engineers who support customers throughout the entire project lifecycle. Depending on customer needs, Mixvoip can provide hands-on guidance, structured knowledge transfer, or a fully managed Microsoft Teams telephony solution, significantly reducing the workload for IT teams and system integrators.

Many organisations face limitations when integrating legacy SIP-based devices such as intercoms, doorphones, access control systems, or paging solutions into Microsoft Teams. Mixvoip addresses this challenge by linking these devices to Teams via its SBC infrastructure, enabling businesses to modernise collaboration without replacing critical on-site equipment.

Mixvoip also supports number portability in more than 25 countries, allowing organisations to retain local and international phone numbers while centralising voice services within Microsoft Teams. This flexibility is particularly valuable for enterprises operating across multiple regions that require a consistent and compliant telephony setup.

To further enhance reliability for mobile and hybrid users, Mixvoip combines Microsoft Teams telephony with Fixed Mobile Convergence (FMC) SIM cards and a patented mobile application designed to ensure stable voice communication even in challenging network conditions. This hybrid approach strengthens call continuity beyond standard data-only mobile usage.

By combining telecom infrastructure, Microsoft cloud expertise, and highly responsive local support, Mixvoip enables organisations to deploy Microsoft Teams telephony with confidence. The company's consultative approach and managed service capabilities make it a trusted partner for enterprises seeking secure, scalable, and enterprise-grade voice communication within Microsoft Teams.
