Go to and select where to forward your phone calls, such as to voicemail or a number you've set before. Or, to add another number, go to , select Open Call Preferences.
Webex Teams | Forward Phone Calls
If you're going to be away from your desk but don't want to miss an important phone call, you can forward your calls to another phone number. Or, if you don't want to be interrupted, you can send all your calls to voicemail instead. If you forward your calls to another number, you won't get called in Webex Teams anymore. So, be sure to turn it off when you're ready to take calls in the app again.
