Outgoing Calls
Note:
If an emergency number is called while calling line identity
restriction is enabled, calling line identity restriction is disabled so that
the emergency service can identify the caller.
Options for Unsuccessful Calls
The following options are available for unsuccessful calls:
Initiating Callback When Line is Busy
If you cannot get through to a busy subscriber despite repeated attempts,
you can initiate a callback on busy. This function is available for internal
calls.
If you have initiated a callback, the PBX will call you as soon as the other
subscriber has hung up the receiver at the end of their current call. If you
then pick up the receiver, the other subscriber will be called. If the other
subscriber picks up the receiver, the connection for the call will be estab-
lished. The callback procedure in the PBX is then deleted.
Initiating Callback on No Reply
If the subscriber being called does not pick up the receiver, you can initiate
"callback on no reply" to reach this subscriber without having to call them
repeatedly. This function is available for internal calls.
