Debugging H.323 Signaling

Overview: H.323 debug monitors

Command	Purpose
unit#debug gateway h323 signaling	Prints all signaling operations on H.323 interfaces.
unit#debug gateway h323 error	General purpose error monitor of H.323. Always
	enable this when debugging H.323.
unit#debug gateway h323 datapath	Prints operations on the H.323 part of the voice
	data path. Use this monitor if you experience prob-
	lems in the data path (no speech connectivity,
	speech only in one direction). This monitor is not
	needed to debug signaling.
unit#show gateway h323 status	Shows the state of the H.323 gateway. Among
	others: enabled/disabled, RAS registration state.
unit#show gateway h323 call name	Shows all calls ongoing on the H.323 interface on
[detail detail]	context CS with name name.
unit#show call-control provider name	Shows the status of an H.323 interface in context
[detail detail]	CS (call control part of H.323 signaling). Shown
	are all calls currently ongoing on the interface,
	with their call states, signaling peers and voice
	data path parameters.
	name is the name of the H.323 interface. Use
	detail 5 for most verbose output.

See also section “Troubleshooting” on page 558 for further informations on debugging H.323. There are more than 40 debug monitors, such as q931, ras, or signaling. For a list of all available debug monitors, refer to the CLI online help.

Verify an incoming call

Make sure an incoming call is entering correctly context CS. In this example, a VoIP gateway or VoIP phone on the network makes a call to your unit using a gatekeeper. The debug output below shows a normal (work- ing) call setup sequence

unit#enable

unit#configure
