Explanation:
• First the state of the gateway is checked. The state is UP, and the RAS engine is REGISTERED, which
is OK.
• The line
01:00:10 H323 > [EP h323-00c07230] Stack: Allocated new call: 0x00be5968 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
01:00:10 H323 > [EP h323-00c07230] 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 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 tpktchan to
verify that a packet is being sent.
