Direct Routing for Microsoft Teams

Enable full phone system capabilities for Microsoft Teams and Office 365 with direct routing from Infinitel.

Direct Routing is phone system capability within Office 365 which enables you to connect Infinitel’s SIP trunks to Microsoft Teams. Direct Routing allows businesses to use Microsoft Teams to make and receive external calls without requiring Microsoft Calling Plan licenses or on-premise equipment.

If your business is using Microsoft Teams, or if you are looking to replace your existing phone system, Direct Routing could be the ideal communications solution.


Until now, companies were required to purchase calling plans from Microsoft so that they could use Microsoft Teams to make and receive calls. However, Microsoft’s calling plans are not always the most cost-effective and are only available in a limited number of countries. Fortunately, businesses can now choose their own telephony provider when using Microsoft Teams as their phone system, minimising costs, improving efficiency and greatly reducing the complexity of integrating existing voice infrastructure with this world leading cloud platform.

There are many benefits to direct routing, which include:

Choose your own telephone provider

Connect Infinitel’s SIP Trunks to Microsoft Teams.

Cost Effective

Reduce spend with our simple calling plans.

Stress Free Migration

Smooth migration to Microsoft Teams with very little impact on users.

Easy Admin

Reduce the complexity of integrating existing voice systems with Microsoft Teams.


Fully Managed

Completely managed service with a true 99.999% uptime SLA.

Global SIP Network

We connect your business to the world with our global IP network.


Manage one unified and consolidated audio, video, and web conferencing solution rather than several products from multiple providers.

We make the process of integration, simple and effective, ensuring productivity is kept at the highest level.

Infinitel’s Direct Routing Service helps organisations to deploy phone system capabilities for Microsoft Teams and Office 365 quickly, cost-effectively and easily.

Direct Routing from Infinitel is a fully hosted solution that allows businesses to use Microsoft Teams to make and receive external calls without requiring Microsoft Calling Plan licenses or on-premise equipment.

This involves hosting a Microsoft Teams-certified Session Border Controller (SBC) in our network, which is connected to our SIP Trunks. Another trunk is then established between the SBC and Microsoft Teams in the cloud. Once connected and configured, users that have applied the Microsoft Phone System licence can make and receive calls using Microsoft Teams.

Due to its fantastic reputation and unending dependency, we use Ribbon Communication’s Microsoft-Teams certified SBCs to deliver our Direct Routing service. Ribbon is one of only a small number of vendors whose SBCs are certified to work with Direct Routing for Microsoft Teams.

Ribbon has the largest portfolio of Microsoft-Teams certified SBCs. Whether you are a small office or large headquarters, we can provide a Direct Routing solution for you.

Infinitel are a great company with excellent customer service! They work hard to get you the best possible deal and are very helpful every step of the way. Would definitely recommend to anyone.

Excellent service with step by step updates. Faultless.

Mark Sidebottom

After having problems with a previous IP phone service provider we decided to move to Infinitel after a recommendation.  Andrew kept me informed all the way through the switch over process which was smooth and simple.  Since then Andrew has always been available to speak to and quickly rectified any teething problems we had.  I would highly recommend Infinitel for internet phone services.

We approached Infinitel with a really specific brief.  What we were looking for as a company was a particularly niche solution that really needed to work.  Andrew and his team turned this solution around with 24 hours and turned something that I had been trying to implement for over 12 months, in to a really easy and simple solution.  From start to finish, the process was easy and streamlined and has given us exactly what we are looking for as a company rather than what a company “thinks” we need.  They come highly recommended from us

Apex Computing Services has worked with Infinitel on many projects including replacing our own telephone solution in our office. We needed very specific features including reporting and monitoring of calls. We also required a whisper function that would allow us to be able to assist and prompt engineers when completing IT support calls to customers. The support we received from Infinitel was excellent and we now have a system that is fit for purpose. The system was delivered on-time, within budget and with little disruption to the business. Thank you!

Yvonne Hope
Chief Executive Officer

Of all the suppliers to deal with, telecoms and mobile phone suppliers in my experience are the worst. When I met Andrew Platt is was clear he is someone who cares about what he does and has very high standards of customer service. The transition of Barnabus mobile phones from EE to Vodafone went very smoothly and even setting up our new phones was painless. Andrew has made our new contract easy to understand and competitively priced, so that we can show value for money to our supporters. Thank you Andrew, we never knew that mobile phone companies could be like Infinitel!

David Maude
Managing Director

Andrew and the team consistently astound me with the speed they act whatever our demanding enquiry is!.
