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 information on 

.) 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 

• 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.
