By adding phone lines to the Microsoft Teams Phone System, users have access to the PSTN (Public Switched Telephone Network), with Teams as the cloud-based PBX.
Customers have two options for access to the PSTN: Microsoft Calling Plans or Direct Routing using SIP Trunks. Each are detailed below.
By working with Telecom Café and our vast portfolio of SIP trunk providers, clients can utilize pooled SIP trunks versus the one-trunk-per-user model at Microsoft.
Pooled and shared SIP trunks are more reliable and cost-effective.
We can help design a program specifically for you, that makes the Microsoft Teams Phone System and third – party SIP trunks a seamless solution.
