Hello ,

We have an issue with third party video conferencing device.

All the incoming video calls are working fine, but while making outbound video call it drops after 5 seconds on dot. This has not bee working since the device is setup.

The connectivity is something like below.

Video Conferencing unit -> Switch-> ASA firewall (9.1(2) ) -> internet -> End point.

Here are timout values i have in my firewall.

sh run timeout
timeout xlate 3:00:00
timeout pat-xlate 0:00:30
timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02
timeout sunrpc 0:10:00 h323 0:05:00 h225 1:00:00 mgcp 0:05:00 mgcp-pat 0:05:00
timeout sip 0:30:00 sip_media 0:02:00 sip-invite 0:03:00 sip-disconnect 0:02:00
timeout sip-provisional-media 0:02:00 uauth 0:05:00 absolute
timeout tcp-proxy-reassembly 0:01:00
timeout floating-conn 0:00:00

Any help in this regard is highly appreciated.

checking the log file (forwarding across to a syslog server for a long term view) and/or creating a capture which you can review with wireshark .pcap file

good luck

This issue is caused due to

This issue is caused due to  ASA firewall  was performing deep packet inspection and dropping specific traffic ( TCP 1720)  from H323 and H225 stream. I have removed the inspection for that specific traffic flow and it started working fine.
