We recently upgraded our PIX from 7.0(2) to 7.2(4), and this appears to have broken our video conferencing connections between Polycoms at two of our sites. We have a site that can connect us, but they can't see us. However, we can't establish a connection from our end. This has been going over a VPN connection between the two sites, but in troubleshooting we decided to use the static nat to a public IP and connect using this. The problem still exists. There is an inspection rule for h.323 and h.225.
