Outgoing Calls
Initiating Callback on Busy
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 central office (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/central
office.
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 central office 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/central office.
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.
Initiating Callback on Busy
Requirements:
– Knowledge of the telephone and its menu options
– For external calls: The given technical requirements for a callback on busy (for instance, not
all network providers provide callback on a Point-to-Point connection)
If the connection you are calling is busy, proceed as described in the following.
1.
Select recall.
2.
Press the
softkey.
3.
Hang up the receiver.
