SmartWare Software Configuration Guide 52 • VoIP debugging
• 09:14:02 CFXS > [EP PHONE] Change state to CONNECTED.: The phone went off-hook and thus accepted
the call. The state of the CS interface goes to CONNECTED. The call is now established.
Debugging H.323 Signaling
Overview: H.323 debug monitors
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
unit(cfg)#debug gateway h323 error
unit(cfg)#debug gateway h323 signaling
unit#debug gateway h323 ras
unit(cfg)#show gateway h323 status

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
[detail detail]
Shows all calls ongoing on the H.323 interface on
context CS with name name.
unit#show call-control provider name
[detail detail]
Shows the status of an H.323 interface in context
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.
