Microsoft Teams SIP Trunk

A Simtex Microsoft Direct Route SIP Trunk is the missing link between your Microsoft Teams tenancy and the Public Switched Telephone Network (PSTN) allowing you to make and receive standard phone calls. This service is often called Phone System Direct Routing.
Our Teams SIP trunk works seamlessly with existing Microsoft 365 accounts, using Microsoft Certified Session Border Controllers (SBC) with full n+1 across multiple states.
