===1.0 Introduction===

This page compares the capabilities of Jabber/XMPP technologies with SIP/SIMPLE technologies. The Jabber/XMPP technologies are defined in the XMPP RFCs produced by the IETF's XMPP WG (closed in 2004) and in XMPP Extensions in the [http://www.xmpp.org/extensions/ XEP Series] published by the XMPP Standards Foundation (XSF). The SIP/SIMPLE technologies are defined in RFCs and Internet-Drafts produced by the IETF's [http://www.ietf.org/html.charters/sip-charter.html SIP WG], [http://www.ietf.org/html.charters/simple-charter.html SIMPLE WG], [http://www.ietf.org/html.charters/sipping-charter.html SIPPING WG], [http://www.ietf.org/html.charters/geopriv-charter.html GEOPRIV WG], [http://www.ietf.org/html.charters/xcon-charter.html XCON WG], and [http://www.ietf.org/html.charters/mmusic-charter.html MMUSIC WG]. See the [#legend Legend] for a description of the terms.

===2.0 Basic Instant Messaging and Presence===

Instant messaging (IM) and presence are core functionality for XMPP. For SIP, IM and presence are made possible through specific SIP extensions, collectively known as "SIMPLE" after the name of the IETF's [http://www.ietf.org/html.charters/simple-charter.html SIP for Instant Messaging and Presence Leveraging Extensions Working Group].

===8.0 Multimedia===

Multimedia functionality comprises things like voice, video, file transfer, and gaming. For XMPP, such functions are accomplished as extensions that use XMPP for negotiation and transfer the media data outside the XMPP band. For SIP, the signalling occurs using basic SIP methods and the media data is exchanged using dedicated data transport mechanisms such as RTP.
