H323 Gateway Problem

[harrylawhorn]

Hello, we have a 2621XM router with 12.3(10)2600-IX-M. We are using it as a Gatekeeper with CCM 4.0.1. For the most part, everything is fine except when our Polycom Units are in a conference that last over two hours. At the 2 hour mark, the Video Conference terminates.

We stopped the Polycoms from registering with the Gatekeeper and this problem goes away.

Thanks,

HARRY

Harry, We found this problem too, but had to do with a timeout error on the PIX firewall.By default PIX firwall are set to disconnect all H.323 sessions after 2 hours. No sure if that will help.

Thats probably it. We do have a PIX in the mix.

Thanks.

Hi,

you can influence this in the PIX with the "timeout" command. Have a look at the PIX firewall command reference

Can you tell me what you did on the PIX to solve this?

Thanks,

Hello,

the commands

timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 rpc 0:10:00 h225 0:00:00

timeout h323 16:00:00 mgcp 0:05:00 sip 0:30:00 sip_media 0:02:00

should help to solve your problems.

P.S.: I didn´t implement this myself, but have heard about it from a collegue.
