Hi ,
i ' ve a problem , with a VCS Control and some Endpoint Polycom HDX.
I use a TMS and 2 mediablade MCU registered on VCS.
I connect various endpoint with ip address (in the VCS there is a Membership rules for the internal private ip address) , but same endpoint after 2 hours drop a connection.
I examine the problem with a sniffer:
10.253.40.4 is the Endpoint
10.49.64.190 is the VCS Control

from the vcs i can see: (10.49.72.20 is the mediablade - codian MCU)

I DON'T KNOW what can drop the connection.
in my network i've another gatekeeper.
If i register the same endpoints at the other gatekeeper and i call this with the e164 number the connection works very well and there isn't any fault.
Only whit a VCS there is a problem.
The VCS and the other Gatekeeper are uder a pix cisco firewall, bau there a rules that permit all ip from the network.
The specialist have verify the firewall and there aren't any drop.
what can i do ?
i try to modify the timer on the H323 vcs parameters, so:

can you help me , please ?
Thanks in advance
