Interworking between the Session Initiation Protocol (SIP) and the
Extensible Messaging and Presence Protocol (XMPP): Architecture,
Addresses, and Error Handling
draft-ietf-stox-core-08
Abstract
As a foundation for the definition of bidirectional protocol mappings
between the Session Initiation Protocol (SIP) and the Extensible
Messaging and Presence Protocol (XMPP), this document specifies the
architectural assumptions underlying such mappings as well as the
mapping of addresses and error conditions.

Internet-Draft SIP-XMPP Interworking: Core December 2013
1. Introduction
The IETF has worked on two signalling technologies that can be used
for multimedia session negotiation, messaging, presence, capabilities
discovery, notifications, and other application-level functionality:
o The Session Initiation Protocol [RFC3261], along with various SIP
extensions developed within the SIP for Instant Messaging and
Presence Leveraging Extensions (SIMPLE) Working Group.
o The Extensible Messaging and Presence Protocol [RFC6120], along
with various XMPP extensions developed by the IETF as well as by
the XMPP Standards Foundation (XSF).
Because these technologies are widely deployed, it is important to
