H.323 is advertised as working for Webex. All of our invites have a line saying "You can also dial 173.243.2.68 and enter your meeting number." This works fine unless your endpoint is behind a NAT. I'm trying to use this for B2B calls for customers and partners that have older endpoints that only do H.323. Of course they are behind a NAT.
I opened a TAC case and they say it's working as designed. That they don't use an ALG or firewall fixup to change the internal IP addresses in the signaling messages.
But if I call the BlueJeans network H.323 address (199.48.152.152) it works fine. The Zoom H.323 address works as well, as does the Polycom test bridge on 140.242.250.204.
Why is it everyone seems to understand H.323 networking better than the Webex video team?
