Call Waiting Tone
You can also enable or disable the playing of a short "Call Waiting Tone" when
there is an incoming call on your phone. This feature is enabled by default. If you
have Call Waiting enabled, and a call comes into the line for which you are on an
active call, a tone is audible to notify you of that incoming call. The tone is also
audible to the caller to indicate to that caller you are currently on another call.
A User or Administrator can configure this feature. An Administrator can
configure this feature using the configuration files or the Aastra Web UI.
