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 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:
• 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 Mitel Web UI.
