Hi. In my office I have a Pix Firewall 525. That equipment had the 6.3 software version and it was updated to 7.2(4) and now I have a problem: When I try to do a Videoconference with a Polycom Camera, is no possible to connect. I've checked the protocols and I see that with this version, the PixFirewall doesn't manage the "fixup" command for use the h323 protocol. this was changed for a MPF command, because when in the pix I wrote "fixup protocol h323" I recieve an answer "INFO: converting 'fixup protocol h323' to MPF commands". Somebady can tell me how can I do to activate this service again? I think that for this reason I can't use the Videoconferece System. Thanks a lot.
