Options for Unsuccessful Calls

Telephoning > Outgoing Calls > Options for Unsuccessful Calls

The following options are available for unsuccessful calls:

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 established. 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.

If you have initiated a callback, as soon as the other subscriber has hung up the receiver to end the call, the PBX will call you. 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 established. The callback procedure in the PBX is then deleted.

Note: Callback is not possible in certain situations, such as when calling an external number, when a public exchange is involved, or during a provider transition. In this case, use the power dialling function.

Initiating a Priority Call when Do-Not-Disturb is Enabled

If it is essential that you reach a person (in emergencies), the do-not-disturb function can be circumvented by a priority call from an internal telephone.
