Call Waiting
With Call Waiting, during a call, if another caller is trying to reach 
you, you will hear a soft beep every 5 seconds.
If you have also subscribed to a Caller Display Service, the caller’s 
number (or name if stored in the Phonebook) will be shown on 
the display for 20 seconds, after this time the display will return to 
your rst caller’s details.
Instead of the engaged tone, the second caller will hear an 
announcement to hold as you are aware that they are waiting.
You must subscribe to your network’s 
Call Waiting service for Call Waiting to 
work. A fee may be payable.
