>>> SRTP is an RTP profile. My comment was that if this is for WebRTC only, then  only SRTP can be used, and not plain RTP. Using “(S)RTP” rather than “SRTP” in this draft suggests that the secure profile is optional, which isn’t the case in WebRTC. If this is for more general use than WebRTC, then “(S)RTP” is fine.

I'm happy to change it to SRTP... Let's see what Magnus thinks...
