I have a VG3825 registered with two Callmanager Subscribers, and this VG keep registered and unregistered couple of times each day during the working hour, and not happened after hour, the following is part of the debug logs: debug ccm events, debug ccm errors, debug ip tcp trans and debug mgcp packets.

Any clue will be appreciated.

Thanks,

Topology?

***TCP0: RST received, Closing connection

This is because either TCP socket was reset by a sec device or in fact D channel went down

hence RST of TCP socket was necessary

Any FW between CCM or MGCP GW?

Have you tried disabling internal CCM firewall from CCM CLI if using Linux?Also start gathering detailed CCM SDI and SDL traces for the moment

Event viewer or SysLog viewer...

MGCP vg3825 is working as SRST on siteA, CCM1 is the primary for vg3825 on siteB, CCM2 is the backup for vg3825 on siteC, there are firewalls and routers between each sites. This is windows system not Linux. I will update some trace files if you need. Thanks.
