Debugging Sip Signaling - Patton electronics SmartNode Series Software Configuration Manual

42 • VoIP debugging
• First the state of the gateway is checked. The state is "UP", and the RAS engine is "REGISTERED", which
is OK.
• The line "

tells that there is a new call incoming from H.323. This means that transport layer is OK. If there is no
debug output at all, try to use "debug gateway h323 tpktchan", which monitors all H.323 socket TCP traf-
fic.

dial to H.323 network with the given call parameters. If you can't see any H.323 SETUP message on the
net, or if the called gateway does not indicate any H.323 message received, use "debug gateway h323 tpk-
tchan" to verify that a packet is being sent.

Purpose
Prints all SIP messages that are sent / received.
This is a good monitor to start with when debug-
ging SIP. If detail is increased (up to 5), more ver-
bose message content is printed.
General purpose error monitor of SIP. Always
enable this when debugging SIP.
Prints all actions concerning SIP registration mech-
anism.
Prints all signaling operations on SIP interfaces.
Prints operations on the SIP part of the voice data
path. Use this monitor if you experience problems
in the data path (no speech connectivity, speech
only in one direction). This monitor is not needed
to debug signaling.
Shows the state of the SIP gateway. Among others:
enabled/disabled, RAS registration state.
Shows all calls ongoing on the SIP interface on
context CS with name name.
Shows the status of an SIP interface in context CS
(call control part of SIP signaling). Shown are all
calls currently onging on the interface, with their
call states, signaling peers and voice data path
parameters.
name is the name of the SIP interface. Use detail 5
for most verbose output.
