Requirements for SIP-Based Session Peering
Abstract
This memo captures protocol requirements to enable session peering of
voice, presence, instant messaging, and other types of multimedia
traffic. This informational document is intended to link the various
use cases described for session peering to protocol solutions.
Status of This Memo
This document is not an Internet Standards Track specification; it is

1. Introduction
Peering at the session level represents an agreement between parties
to exchange multimedia traffic. In this document, we assume that the
Session Initiation Protocol (SIP) is used to establish sessions
between SIP Service Providers (SSPs). SIP Service Providers are
referred to as peers, and they are typically represented by users,
user groups, enterprises, real-time collaboration service
communities, or other service providers offering voice or multimedia
services using SIP.
A number of documents have been developed to provide background
information about SIP session peering. It is expected that the
reader is familiar with the reference architecture described in
[ARCHITECTURE], use cases for voice ([VOIP]), and instant messaging
and presence ([RFC5344]).
