May213,

Here is a snapshot of a firewall traffic monitor on the Asterisk end.
Interestingly the first TCP connection which looks like a control
connection to me does not send back any traffic. It initially sent 750
bytes. Then it periodically receive packets but does not reply. The
increment is around 53 bytes.

 # 	Source IP 	Source Port 	Destination IP 	Destination Port 	Protocol
	Src Interface 	Dst Interface 	Tx Bytes 	Rx Bytes
1	172.17.135.2	4488	172.17.137.11	1720	TCP	OPT	LAN	750	2513
2	172.17.135.2	51081	172.17.137.11	12113	UDP	OPT	LAN	9288	7728
3	172.17.135.2	51080	172.17.137.11	12112	UDP	OPT	LAN	4239200	207800
4	172.17.135.2	4489	172.17.137.11	12037	TCP	OPT	LAN	9687	3893

Here is the snapshot in 12.5 minutes:

 # 	Source IP 	Source Port 	Destination IP 	Destination Port 	Protocol
	Src Interface 	Dst Interface 	Tx Bytes 	Rx Bytes
1	172.17.135.2	4488	172.17.137.11	1720	TCP	OPT	LAN	750	2972
2	172.17.135.2	51081	172.17.137.11	12113	UDP	OPT	LAN	16416	13616
3	172.17.135.2	51080	172.17.137.11	12112	UDP	OPT	LAN	7405600	716400
4	172.17.135.2	4489	172.17.137.11	12037	TCP	OPT	LAN	16164	6290

Here is a final snapshot at 16 minutes when the call was dropped:

# 	Source IP 	Source Port 	Destination IP 	Destination Port 	Protocol 	Src
Interface 	Dst Interface 	Tx Bytes 	Rx Bytes
1	172.17.135.2	4488	172.17.137.11	1720	TCP	OPT	LAN	750	3125
2	172.17.135.2	51081	172.17.137.11	12113	UDP	OPT	LAN	21060	17664
3	172.17.135.2	51080	172.17.137.11	12112	UDP	OPT	LAN	2400	0

As you see the non-responsive TCP connection did not drop but another TCP
connection was dropped and one of the UDP connections was reset.

This test pretty much rules out a TCP timeout as a cause of the
disconnect.

Some H323 control signaling is left not answered by Asterisk.

Thank you,
Vladimir
