Enterprise Telephony for Microsoft Teams (ET4T) powered by Swisscom

Make phone calls with Microsoft Teams?

Yes, because with Enterprise Telephony for Microsoft Teams, Teams is more than just a workstream collaboration tool.

Microsoft Teams, the teamwork hub, is now a telephone exchange as well: with Swisscom Enterprise Telephony for Teams, you can now make and receive phone calls from anywhere in the world directly via the Teams client. Your employees can therefore communicate not only more efficiently and effectively, because everything takes place on one platform, but they can also collaborate more easily through the integrated Office 365 apps.

How does Enterprise Telephony for Teams work?

Microsoft Direct Routing helps to connect Office 365 to the telephone network. To use it, a session border controller (SBC) and an SIP trunk are required. However, we host and manage everything you need in our highly available Swisscom data centres, so you don’t need to worry about anything.
