Direct Routing for Microsoft Teams

Direct Routing For Microsoft Teams

What is Direct Routing?

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

We’ve combined our SIP services with Microsoft Teams to give you a direct routing capability which provides PSTN calling to Microsoft Teams.

Microsoft Certified Session Border Controller

Infinitel leverages Ribbon’s Microsoft Teams-certified Session Border Controllers (SBC’s) to support our Direct Routing for Microsoft Teams service.

Ribbon is one of only two SBC vendors officially certified by Microsoft to integrate its SBCs with Teams, connecting legacy systems and endpoints to Calling in Teams to integrate voice services.

There are two primary approaches to deploying Direct Routing

Depending on the expertise of your internal IT team, the SBCs can be deployed in 2 ways.

Customer Deployment

This scenario is ideal if you have the in-house expertise and prefer to manage voice infrastructure internally. Microsoft Teams-certified SBC’s are deployed within the customer environment and management is the responsibility of the internal IT team.

For businesses who require on-premise SBCs and prefer a partner to manage them, this is something that can be supported by Infinitel.

Hosted Deployment

This is the ideal scenario if your business is embracing cloud-based services. The Microsoft Teams-certified SBC is hosted within our fully managed infrastructure  with 24/7 Support.

Infinitel’s team of professionals are ready to answer your questions and guide you to the right solution. Call us on 03339960029 or click here to send us an email.

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
