Announcement service
The announcement service is for incoming external calls, but if required it can also
be used for internal calls via a call distribution element. If a call from A is not answe-
red within a preset delay time by internal user B (who is either free or for whom call
waiting is enabled), the caller will hear a welcome announcement (provided the
call has not been rerouted to the alternative destination (Capolinea)
Once the announcement has been made, the caller obtains either the ring-back
tone, music, a pause or another announcement is made. This can be repeatedly en-
dlessly, with the possibility of playing back up to 20 different Wave files. A succes-
sion consisting of wave life, pause signal and pause duration is referred to as a se-
quence.

Announcement service
As long as caller A is connected with announcement service, user B's terminal conti-
nues to ring. If B answers, the connection is put through immediately.
If B does not answer within the time configured under CM_2.3.3.2_
duration
in the AMS Configuration Manager, the connection is cleared down.
