Harald,

Yes you are missing something. The registry you pointed at are the one for RTP profiles. The one containing the combinations with transport are SDP specific.

http://www.iana.org/assignments/sdp-parameters/sdp-parameters.xhtml#sdp-parameters-2

Cheers

Magnus

Hi Harald,

Could you please let me know the specification which indicates SRTP/AVPF/TCP
profile in Sec 2.2 of draft-ietf-rtcweb-transports-01.

Thanks
Partha



That's a good question!

http://tools.ietf.org/html/rfc4571 defines TCP/RTP/AVP, but there doesn't seem to be a corresponding defintion for SRTP/AVPF over TCP.

Neither is the RFC 4571 profile registered at IANA - I think both that and the DTLS forms should have been at http://www.iana.org/assignments/rtp-parameters/rtp-parameters.xhtml#rtp-parameters-7 - but this registry seems so short, I wonder if I'm missing something.
