VCS drop a connection with same endpoint Polycom HDX after 2 hours

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: is the Endpoint is the VCS Control


from the vcs i can see:   ( 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
