Having one more thing to implement before something works is not critical, but makes a difference. If you support DTMF in RTP you already have a requirement that you SHOULD only do that over SRTP. If rtcweb supports telephony-events, we are already on the SRTP side as almost mandatory. I think it's easier to reach an agreement on SRTP being mandatory than DTMF being dis-allowed. Appendix A of RFC 4733: "The Security Considerations section is updated to mention the requirement for protection of integrity. More importantly, it makes implementation of SRTP [7] mandatory for compliant implementations, without specifying a mandatory-to-implement method of key distribution." "The telephone-event payload defined in this specification is highly compressed. A change in value of just one bit can result in a major change in meaning as decoded at the receiver. Thus, message integrity MUST be provided for the telephone-event payload type. To meet the need for protection both of confidentiality and integrity, compliant implementations SHOULD implement the Secure Real-time Transport Protocol (SRTP) [7]." Section 6 of RFC 4733 - an RFC that makes 2833 obsolete. /O
