A three site bridge IP call.
Site 1 The Bridge Polycom/HDX 8000 HD/Release - 188.8.131.52-4852
Site 2 End Point Polycom/VSX 7000A/Release 8.5.2 - 05Nov2006 01:36"
Site 3 End Point Polycom/HDX 9000 HD/Release - 3.0.6-37004.
Site 3 dials into Site 1 and audio/video is fine.
Site 2 now dials into Site 1, Site 3 looses video, but audio is fine
Site 3 now hangs up and redials Site 1 while Site 2 remains in the call. Video is now present along with audio.
Site 3 Dials Site 2, point to point, with no video/audio issues.

We're not sure where to start to troubleshoot this issue.The easy workaround has been for Site 3 to always dial in last
welcome to the Polycom Community.
Once the 2nd call is added to your Multipoint HDX call, the Endpoint will re-negotiates video by closing and re-opening the video channel.
You would have to check via a wireshark trace what is happening and if the firewall blocks any ports due to the above.
