Call waiting
When you are in a call, another incoming call will be announced visually by the symbol and
acoustically by the sound of a double beep; you will also see caller ID on-screen if it is being
transmitted. Switch to visual or acoustic announcement only or turn call waiting off on the phone’s web
interface.
The default setting is "on", which means that calls are announced both acoustically and visually. See
"Call Waiting" on page 54 on how to use this feature.
