Common questions

Frequently asked questions

What is Teams telephony?

It’s the phone-calling capability added to Microsoft Teams so you can call external numbers.

How is it delivered?

Via Direct Routing — we connect Teams to the phone network with your numbers.

Is it reliable?

Yes — it runs on our managed, resilient platform.

Direct Routing features

Proper calling inside Microsoft Teams, on our own voice network.

Direct Routing is the flexible, accessible and cost-effective alternative to Microsoft Calling Plans: your team makes and receives external calls from Teams exactly as before, and the calls are carried on Telexico SIP trunks through session border controllers we run ourselves.

Our own session border controllers

Direct Routing links the public telephone network to Teams through SBCs on our own SIP platform rather than a resold third-party bridge, so faults and changes are handled directly.

Encrypted, resilient voice

Encryption over the internet, plus the voice resilience of a platform that fails over across data centres.

01, 02, 03 and 08 termination

UK geographic, 03 and 08 numbers terminate natively on the Teams endpoint with no number translation. Termination charges still apply on 08 numbers.

Network- and number-level resilience

Tailored business continuity: if Teams or your connection is unavailable, calls to your numbers divert where you tell us, so you never miss a call.

Dedicated interconnect into Azure

A dedicated interconnect to Microsoft Teams in Microsoft Azure for higher service speeds and security.

Cheaper than Calling Plans

Make full use of the Microsoft 365 licences you already pay for and route the calls through a provider you choose, at per-minute and rental prices below Microsoft’s bundles.

Mixed estates are normal: Teams for the office staff, desk and DECT handsets for reception, the warehouse or the shop floor, and the Telexico Mobile App for everyone on the move, all on the same numbers and the same bill.
