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 using the "Play Call Waiting Tone" parameter. 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 using the Aastra Web UI. An Administrator can
also configure this feature using the configuration files.
