Options for Unsuccessful Calls
The following options are available for unsuccessful call:
Initiating Callback on Busy
If you cannot get through to a busy subscriber despite repeated attempts, you can initiate a callback on busy. The PBX supports the service attribute "Automatic callback on busy (CCBS)". This service attribute is required for an external call.
If you have initiated a callback, as soon as the other subscriber has hung up the receiver to end the call, the PBX (for an internal call) or public exchange (for an external call) calls you. If you then pick up the receiver, the other subscriber is called. If the other subscriber picks up the receiver, the connection for the call is established. This deletes the callback procedure in the PBX/public exchange.
Initiating Callback on No Response
If the person being called does not pick up the receiver, you can configure callback on no response in order to reach this person without having to call him repeatedly. The function can be used for both internal and external calls. The service attribute "Callback on no response (CCNR)" is supported by the PBX. This service attribute is required for external calls.
If you have initiated a callback, as soon as the other subscriber has hung up the receiver to end the call, the PBX or public exchange calls you. If you then pick up the receiver, the other subscriber is called. If the other subscriber picks up the receiver, the connection for the call is established. This deletes the callback procedure in the PBX/public exchange.
Initiating Priority Call for Do-not-disturb
If, for example, a person must absolutely be reached in an emergency despite the do-not-disturb function, the do-not-disturb function can be circumvented by a priority call from an internal telephone.
