27.7 Debug ISDN Data
To obtain actual information about the ISDN layers you can use the ISDN debug commands. The
show command displays information about the actual ISDN status and about actual ISDN sessions.
The debug command enables the ISDN debug monitor to show layer 1 to layer 3 information. This
information is mainly useful for experienced users.

27.8 Debug H.323 Data
You can use the H.323 debug commands if there are problems with setting up and establishing calls
over H.323. The show command displays the actual H.323 configuration or the actual status of the
H.323 stack, e.g. ongoing calls or registration state. The debug command enables the H.323 debug
monitor to show specific information for a call, such as status, used codecs or transposed messages.
There are more than forty different debug monitors such as 'q931', 'ras' or 'signaling'. For a list of all
available debug monitors refer to the CLI online help.
