DTLS-SRTP Handling in SIP Back-to-Back User Agents
RFC 7879, “DTLS-SRTP Handling in SIP Back-to-Back User Agents”, is a Proposed Standard document published in May 2016 by R. Ravindranath, T. Reddy, G. Salgueiro, V. Pascual, P. Ravindran. The canonical text is published by the RFC Editor.
Abstract
Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) exist on the signaling and media paths between the endpoints. This document describes the behavior of B2BUAs when Secure Real-time Transport (SRTP) security context is set up with the Datagram Transport Layer Security (DTLS) protocol.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
