2.8 Caller ID on Call Waiting
The 2757 supports Caller ID on Call Waiting. With this service, the 2757 will notify you if you
receive a second call while you are on the phone. It will also display the number of the second
call. Please note that this service must be provided by your ISP or VoIP PBX.
When you are on a call and receive another call, you will hear a notification tone and the LCD will
show the calling number.
To accept the incoming call press ‘flash.’ This will place the existing call on hold. If you hang up
the phone while you have a call waiting, the waiting call will become as a new call. The phone
will make a tone to alert you that you have a call. You can accept this call by pressing ‘Answer.’
You may toggle between the calls using ‘flash.’
