Ability to Disable Call Waiting
Currently on the IP phones, the call waiting feature notifies the user currently on
the phone, of a new incoming call. Release 2.1 allows a User or Administrator the
ability to 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 will receive busy unless “Call Forward Busy” or “Call Forward No
Answer and Busy” is configured on the phone. It will then forward 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:
• on the 57i CT bases, and the handset is currently on a call, all additional
incoming calls are rejected on the handset.
• 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 Cancels Dialing” parameter is ignored because the
incoming call is automatically rejected.
• 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.
