Direct Routing for Microsoft Teams

Direct Routing for Microsoft Teams - make and receive business phone calls

Organizations are already using Teams for video conferencing, file sharing and chat.  Microsoft Phone System Direct Routing is the service inside of Teams that allows organizations to connect external phone lines and use Teams as an office phone system.

Ribbon provides the Microsoft certified Session Border Controller (SBC) required to connect Teams to a Communications Service Provider (aka phone lines). Teams uses IP-based voice connections, commonly referred to as SIP Trunks to connect to the rest of the world. Ribbon’s SBCs secure these connections and assure interoperability so organizations can select from hundreds of service providers across the globe.

Organizations can use Teams for all their business calls or slowly migrate from a legacy PBX, depending on their needs.  And since Teams clients work on a PC/Mac or smartphone, users can make and receive calls from almost anywhere, on any device, staying connected and productive.
