Hello, I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comments. Summary:  ready This is a small document with many references to external  documents and their related security sections. It seems appropriate to me. Typo:   please remove the additional "security" in the following sentence: Likewise, consult the RTP base specification for security RTP-based security considerations. Cheers,   Vincent
