(copying Flemming) Good draft. Very helpful.
On the SDP side of things. I didn't seen anything in the SDP format that specifically indicated in the offer that you are trying to setup DTLS-SRTP. Is the assumption that if there is no indication besides the RTP/SAVP in the tcap, that DTLS-SRTP may be negotiated, and that therefore we do not need an explicit indication that DTLS-SRTP is supported? Do we think it's good enough? In other words, is RTP/SAVP without a=crypto or a=key-mgmt good enough to indicate DTLS-SRTP? Or should we have another attribute? A side comment is that the example shows usage with Best-Effort SRTP. My take is that it could also be used in "DTLS-SRTP-always" mode by having the m-line use UDP/TLS/RTP/AVP instead of RTP/AVP and not using a a=tcap/a=pcfg line. It would probably be worthwile to describe it in the draft. _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
