RFC 4976: Relay Extensions for the Message Sessions Relay Protocol (MSRP)

Still current, but amended. Parts of this document are changed or extended by RFC 7977, RFC 8553, RFC 8996. Read both.

In plain English — editorial summary, not part of the RFC

Two separate models for conveying instant messages have been defined. Page-mode messages stand alone and are not part of a Session Initiation Protocol (SIP) session, whereas session-mode messages are set up as part of a session using SIP. The Message Session Relay Protocol (MSRP) is a protocol for near real-time, peer-to-peer exchanges of binary content without intermediaries, which is designed to be signaled using a separate rendezvous protocol such as SIP. This document introduces the notion of message relay intermediaries to MSRP and describes the extensions necessary to use them. [STANDARDS-TRACK]
