The goal of this project is to implement a bidirectional signaling and media gateway for Presence, Instant Messaging including multi-party chat, Audio, Video and File Transfer between SIP and XMPP protocols. This research and development project is part of the WormHole Project sponsored by [http://nlnet.nl/project/xmpp-sip/ NLNet and AG Projects].

== Deployment Scenario ==

By pointing the correspondent DNS records for the SIP and XMPP services to the address of the gateway, any packet sent to or connection established to the gateway by one of the protocols is transparently translated into the other.

== Specifications ==

 * SIP (RFC3261) and related RFC for ICE, RTP, MSRP (too many to mention)

 * XMPP core (RFC 6120) http://xmpp.org/rfcs/rfc6120.html

 * XMPP extensions http://xmpp.org/xmpp-protocols/xmpp-extensions

 * Instant Messaging and Presence http://xmpp.org/rfcs/rfc6121.html

 * File Transfers http://xmpp.org/extensions/xep-0096.html

 * Audio and Video

  * Jingle http://xmpp.org/extensions/xep-0166.html

  * Jingle RTP http://xmpp.org/extensions/xep-0167.html

  * Jingle ICE (UDP) http://xmpp.org/extensions/xep-0176.html
