I use pix 506. When I config the tandberg endpoint at inside to network and opened the standard tcp/udp port which provided by the vendor. It can call out or in. However, when I enable the encryption option at tandberg endpoint to encrypt the meeting. It can't dial in or out again. Have anyone know the solution and share with me. Thanks!
I guess syslog should give you further information on this. What is the PIX OS you are running? Just for the testing purpose, have you tried opening up all IP communication from outside to inside, or alteat between your particular hosts.
It seems to be no change. If I remove the "fixup protocol h323", I can make a call without encryption. But there is no image at inside VC and outside VC can appear image. If I try to dial with encryption, it can't make the call. I want to download 6.3.3. But I can't download it when I use the CCO login.
