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.
when the VC system put directly to the router with real IP it works well bidirectional.

Is that with H323 only, not SIP? If that is the case look like you hitting CSCsg93482
H.329 protocol is not supported for video conferencing on the PIX/ASA platforms.
PIX/ASA running 7.X code where H.323 endpoints are both inside and outside of the firewalls successfully making dial in and dial out calls from the H.323 endpoint using H.225, H.245, and H.263 protocols. When we try to establish H.239 communications after the video call is established, the H.239 failed.
Upgrade of your ASA to 7.2(1) 98.2(0.71)M should fix this.
