I would like to add a Sony PCS-1P (H.323) terminal to an existing Cisco (IP/VC 3540, software version 3.2)+ Polycom (Viewstation EX - several terminals) installation. The hole infrastructure runs on H.323, and there's no CCM, so SCCP isn't an option.
The gatekeeper is IOS based.
The Sony can register just fine to the gatekeeper, and can use all of it's facilities. Calling through the gatekeeper, but in point to point mode, it works fine, there are basically no interoperability issues with the Polycom terminals - even remote camera control works between them.
But when I want to use the MCU for a conference call, the Sony PCS-1P gets no image. It gets the sound and it can send both sound and video (other participants can see the image transmitted from the Sony camera). On the conference control web application, when the conference is accessed, each participant has usually 4 icons next to it: Microphone, Speaker, Monitor and Camera.
Well, the Monitor icon is completely missing from the Sony device, not just crossed over, like when the camera or microphone gets disabled.
All codecs, fps-s, etc. have been double checked (and tried several methods) to ensure they are the same both on the Sony and on the MCU. There should be no access right problems (I couldn't find any. Is there a place I should look specifically?)
As far as I can tell, there's no way to reenable the monitor, and I can find no indications in the logs either (they only record registering/unregistering devices).
ANY idea would be really appreciated, as I'm completely blocked by this issue.
