Source note · SRTP and media encryption negotiation
For SRTP (as opposed to SRTCP), RFC 3711 makes the authentication tag RECOMMENDED rather than mandatory.
Checked 2026-09-23
Authentication tag: configurable length, RECOMMENDED. / SRTCP message authentication is MANDATORY and thereby protects the RTCP fields to keep track of membership, provide feedback to RTP senders, or maintain packet sequence counters.
