What Is Microsoft Teams Direct Routing?
Microsoft Teams Direct Routing connects your Teams environment to the public telephone network (PSTN) using Session Initiation Protocol (SIP) trunks.

- Keep existing phone numbers and carriers.
- Connect remote offices and hybrid teams under one system.
- Integrate advanced call management features.
- Maintain compliance and enterprise-grade security.
In essence, ACS transforms Microsoft Teams from a collaboration tool into a unified communication powerhouse.

How do you implement Intuity SIP Direct Routing for Microsoft Teams?
Implement Microsoft Teams for internal use
We begin by rolling out Microsoft Teams across your organization to strengthen internal communication.
Secure the right licenses and choose a provider
NBefore launching Direct Routing, you'll need Microsoft licenses that include audio calls and phone system capabilities for each user. Here, it's essential to choose a provider with proven experience.
Set up SBC, SIP and Media Bypass
Direct Routing relies on a Session Border Controller (SBC) — also known as a PSTN Gateway — to connect Microsoft Phone Systems with your provider's network.
Transfer existing numbers
The final step is to port your current phone numbers to Microsoft Teams. Our team manages this process carefully to minimize downtime and avoid disruption.
