# Calling Features

**Calling Features**

Once you have the Connector operational it is important to understand what is and is not possible as a Microsoft Teams user making and receiving calls.

With the Teams Application - an option you have - you can add more capabilities.

Note that some features remain Teams Native due to Microsoft constraints.
