9. 2. 2 Notifications supported by the system
Notifications are used for transmitting information on a connection’s current status and
can be shown for example on the display of system phones. The notifications sup-
ported by the public ISDN network are also partly supported by the system, converted
accordingly for private QSIG networks, or forwarded transparently to connected ISDN
terminals.
Notifications sent to the public ISDN network by the communication server can be in-
hibited in the trunk group configuration ( =bg) using the parameter Send notifica-
tions.
The following table provides an overview of the notifications supported by the commu-
nication server or forwarded transparently:

Depending on the network provider, redirecting information is also transmitted with incoming calls, in addition
to the notification. With outgoing calls the communication server also sends the redirection information in-
