Additional Features
Enable/Disable Call Waiting
The call waiting feature notifies the user on an active call, of a new incoming call. You can
disable the call waiting feature, so that the new incoming call is automatically rejected by the
phone with a busy message.
If you disable call waiting on the phone, and the user is on a call, any further incoming calls
receive busy unless “Call Forward Busy” or “Call Forward No Answer and Busy” is
configured on the phone (for more information on
Call Forwarding, see “Call Forward Account-Based Configuration” on page 145.) It then
forwards the call according to the rule configured. The phone can only:
• transfer the currently active call
or
• accept transferred calls if there is no active calls.
If call waiting is disabled:
• intercom calls are treated as regular incoming calls and are rejected.
• pre-dialing with live dial pad disabled still accepts incoming calls.
• the “Incoming Call Interrupts Dialing” parameter is ignored because the incoming call is
automatically rejected (for information on “Incoming Call Interrupts Dialing” see page 172).
• the Missed Calls List does not get updated with details of calls.
• the Blind Transfer feature on the phone may not work if two calls are made to the phone at
one time.
You can disable call waiting using the configuration files or the Aastra Web UI.
