I'm facing a weird problem... The scenario is: Nortel PBX <-> MC3810 <-> GK <-> FW <-> AudioCodes104 <-> FXO Every time a call is maded from a phone on the Nortel PBX to the phone behind the Audiocodes (Nortel -> AudioCodes) the call is established, and after 12 seconds the following error is registered on the LOG: 2008/02/14 12:00:05.227 1 ProxyChannel.cxx(3359) H245d Could not open/connect H.245 socket at X.X.X.X:0 - error 12/115: Input/output error After that, GK stops responding (freezing) and I have to restart it. I'm using: Gatekeeper(GNU) Version(2.2.6) Ext(pthreads=1,radius=1,mysql=1,pgsql=0,firebird=0,large_fdset=4096, crypto/ssl=1) Build(Feb 1 2007, 18:09:05) Sys(Linux i686 2.6.8-24.23-default) Only upgrading could resolve this problem? Or is there any other idea/hint? Just to flash a light, if the FW is suppressed, everything works fine. It's like a problem with AudioCodes-104 behind a FW (even with all ports open to a DMZ IP).
