H.263 negotiation

H.263 negotiation

H.263 negotiation

Hi mates,

I have a question about using H.263.

I have two devices from different vendors (Polycom and Radvision). Both devices supports g.722 for audio and h.263 for video, but for some reason I have bidirectional audio, but only unidirectional video (Polycom presents what Radvision is sending).

When I checked the call information from the Radvision device, I see that it is sending H.263 but is not receiving any video codec from Polycom.

Previous calls from Polycom I see that were negotiated using H.263+T with 4CIF. I understand that H.263 supports all versions, but as I stated Im not receiving video for Radvision device.

Any help or advice would be appreciated...
