Which Microsoft 365 license do I need to make calls with Microsoft Teams?

We tell you the licenses you need for Microsoft Teams to connect your own SIP Trunk with the Teams Connector.

The Microsoft Office suite in general and the Teams software are not rigid products. Rather, they are always a combination of different licenses that determine the actual range of features.

For example, if you want to use Microsoft Teams not only for internal company communication and cooperation, but also to make phone calls over the local network (PSTN), you usually need the additional paid add-on "Teams Phone", which must be booked separately for each seat that is to be able to make phone calls later.

With the following license combinations, you can extend your Microsoft Teams with telephone functions and thus obtain a real solution for Unified Communications (UC).
