4.1 Telephoning
You can start calls directly from the Microsoft Teams interface. You have several options for starting a call:
Calls that are started via the Contact App for Microsoft Teams are carried out on the device that you set under Device for outgoing calls.
If you want to use the Contact Mobile softphone (e.g. with a headset) in combination with the Contact App for Microsoft Teams, you will still need to install the Contact Desktop Client. This is necessary as Contact is not allowed to use the WebRTC capabilities of Microsoft Teams.
Contact is not allowed to send push notifications to Microsoft Teams, for example, on an incoming call to your softphone.
To ensure that you don't miss an incoming call to your softphone with the Contact App for Microsoft Teams, please use the following notification settings in the Contact Desktop Client (if you are using a fixed or mobile device, you will of course be notified by the ringing event of these devices instead).
