Looks like the new CUPC 8 allows video with the deskphone as the controlled device unlike with 7. My client detects my camera and I can choose it but when in a call the camera doesn't power on and under File -> Options -> Video selecting the "settings" button does not bring up the settings of the camera. I have video capabilities enabled on my 7975 phone, my PC is windows XP, the camera is a Logitech notebook and I tired a much new Logitech camera too. I tried this on a windows 7 box with the same set up and Video option is grayed out but I'm sure that's because of windows 7.
Is there another setting somewhen either at the phone level or on CUPS that I need to enable?
We're fighting the same battle. It works fine on Windows XP x86. When you read the release notes (as I just did not long ago) it says that Deskphone Video support is not supported on x64. If you are using x86 then i'm not sure. I have not tested my theory yet though except to test it on Windows XP x86.
This is due to the lack of CDP x64 support not CUPC. CDP and CAST are both required for video to work w/ the desk phone.
