Hi All, I have following query on BFCP.
In the following SDP message from a Tandberg device, it mentions use of BFCP for video media (label:12). Does it mean that without using BFCP, a media session cannot be established on port: 2370 for second video channel? Is there any means to bypass use of BFCP? For supporting content-arbitration or media-arbitration, Is BFCP a MUST requirement?
