Switching Call Waiting On/Off
If call waiting is switched on, you will be notified of any incoming calls if you are already on another call.
If the audible signal and call waiting are switched on, a tone in the receiver will notify the user (when already on a call) that another call is incoming. If the audible signal is switched off, incoming calls will be signalled only in the display.
Note: As of firmware 6.6 (PBX) and 2.4 (VoIP telephone) a comparison between telephone and PBX will be implemented. This function can then be switched on or off in the telephone or the PBX.
Proceed as follows:
Using the telephone (function key or  > Functions > Call waiting)
Tap on Execute.
