8. 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 terminals. The notifications
supported 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 PBX can be inhibited in the
trunk group configuration using the parameter Send notifications = No.
The following table provides an overview of the notifications supported by the PBX
or forwarded transparently:
