Turning Call Waiting On and Off
Call waiting alerts you when you are on a call by ringing your phone and displaying
a status message that another call is ringing. If you turn call waiting off, incoming
calls do not ring your phone if you are on another call, and the caller hears a busy
signal or message.
You can also turn call waiting on and off from your PC using the IP Phone Web
Interface. See the
“Configuring Call Waiting” section on page 69 .
