If a call is currently active, the default setting is to decline additional calls with a busy signal.
By activating the call waiting function, you will be notified of additional incoming calls instead, and the caller will not be automatically declined.
This feature can be activated using the TK-Portal:
|To do this, change the view mode from Easy to Advanced by clicking the Change button (1) in the upper right corner. |
Then click on the slider at Call Waiting (2).
