I also prefer TLS. RFC4474 doesn't require TLS, so ICE is in the draft to demonstrate it is possible to have identity even through a translator and have identity with just RTP (RFC4474 provides identity with just RTP). However, if we used TLS/DTLS-SRTP for identity it would (a) break transcoding (as discussed) and (b) require deploying SRTP. If doubt we are willing to do (a) and (b). -d _______________________________________________ Sip mailing list https://www.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
