Cisco 3511 MCU and Polycom Visual Concert

[tim-griffin]

If I connect two Polycom 7800 endpoints via IP and send content from a PC connected to a Visual Concert at one endpoint, the PC display comes out of the Visual Concert at the receiving endpoint on a VGA projector. When using a 3511 MCU to connect multiple endpoints the content sent from the PC displays on the Monitor at the far ends instead of the projector connected to the Visual Concert. I've tried to enable H.239 and also dual mode on the MCU but it doesn't help. I've also upgraded the MCU to the latest code (3.5.33). I can't find any information on Cisco TAC or on Polycom's website.

Sending content using two or more Polycom 7800 endpoint must works only if the MCU can handled H.239, I do not know if 3511 MCU can handled H.239, may be you just need set a couple of thing in the MCU. A MGC (Polycom's MCU) can use H.329 very well.

For more information, You can go to www.polycom.com->support->video(look for Resources,top left ) and click on "White Papers" find this link "H.239 People+Content - Polycom Patented Technology", it is a PDF doc.

Thanks for the reply. I did set the allow H.239 feature on the 3511 but it didn't help. I'll check out the link you sent me.
