Call Waiting
The call waiting feature notifies a user on an active call on the phone, of a new incoming call. You can disable this call wait-
ing feature, so that the new incoming call is automatically rejected by the phone with a busy message. A User or Adminis-
trator 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 6757i 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 dialpad disabled still accepts incoming calls.
• 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 on a global or per-line basis using the configuration files or the Aastra Web UI.
