Debugging call signaling 636
SmartWare Software Configuration Guide 52 • VoIP debugging
Explanation:
• First the state of the gateway is checked. The state is “UP”, and the RAS engine is “REGISTERED”, which
is OK.
• The line
00:29:03 H323 > [EP h323-00c13dc0] Stack: Allocated new call: 0x00be56b 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 traffic.
• The line
00:29:03 H323 > [EP h323-00c13dc0] Destination Address: TEL:60,60 and below show the
calling and called party properties. In the present case, the called party number is 60.
•
00:29:03 HRAS > Stack: Received Admission Confirm says that the gatekeeper allowed us to accept the
call. Continue debugging call routing if the call does not reach its destination.
Verify an outgoing call
Make sure an outgoing call leaves correctly on text CS and the device. In this example, a terminal on the gate-
way to debug wants to make a call towards a H.323 VoIP network using a gatekeeper. The debug output below
shows a normal (working) call setup sequence
