Precondition: Your phone will permit two parallel VoIP connections (s.

on page 141). 
If call waiting is activated, a caller on one of your VoIP connections will hear the ringer tone 

if you are already on a call using this VoIP connection. This call is announced acoustically 

and visually on your handset screen.
Calls on the fixed line connection are not signalled as call waiting. They are signalled on 

other registered handsets to which the fixed line number has been allocated as a receive 

number. If no other handset is available, the caller will hear the busy tone. 
Accepting/rejecting a waiting call, see page 48.
