Videoconferencing Issues - PIX OS at fault?

Posted on 2009-04-16
Last Modified: 2013-11-16
Hello Everyone,

   We have a Cisco PIX firewall at a remote site running PIX OS 6.3(1). This particular PIX can support up to 6.3(5). I'm trying to figure out if the handling of H323 videoconferencing calls has been significantly changed between the older and newer versions, but I'm having trouble finding adequate documentation. Has anyone had experience with videoconferencing issues such as calls connecting but no video / audio flowing that were resolved by upgrading the PIX? We're using one of the newer Polycom HDX-series codecs. As an aside, I have a fair amount of experience setting up these systems. I don't believe we have an ACL or a fixup issue here, which is why I'm looking to the OS version. Any insight would be greatly appreciated. Thanks!

Best Regards,
Martin Schultz

    There isnt any significant change to the inspection engine in the upgraded version its more or less just bug fixes but anyways I would suggest to replace the PIX firewall as its very old and End Of Life and the last time version released was almost 5 years ago (6.3(5)).
