Call Waiting/Call Waiting Tone

A call waiting feature notifies the user currently on the phone, of a new incoming call. You can disable this call waiting feature, so that the new incoming call is automatically rejected by the phone with a busy message. A User or Administrator can configure this feature.

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 enable/disable call waiting using the configuration files or the Aastra Web UI.
