Dear All,
i have a VC system "Tandbger C60 Model", and ASA firewall. C60 unit is in the inside zone of the firewall and mapped to real IP, from the outside anyone can call me and make avideo call and share his presentation "desktop" without any problem, and also when I make a call is works well, but the problem when trying to share my desktop to the other site, he didn't see the presentation and the call will disconnect after a few seconds.
Hint:
when the VC system put directly to the router with real IP it works well bidirectional.
ASA config:
ASA Version 7.0(8)
