> Actually the "extension" is implemented in terms of RFC 2326 by using "Require" header (12.32 Require).
> So the question is how to get these "Require" headers from OPTIONS request and respond with 200 OK or 551 Option not supported.

Yes, you're correct - the server needs to be fixed so that it notices the "Require:" header, and returns an "551 Option not supported" error in this case.


> The second part of question is how to make a track with "a:sendonly" attribute and accept data.

I outlined this in my previous reply.


> The reverse media transport is part of RTP standard and used in SIP protocol.

Yes, but RTSP is not SIP.
