h1. SIP/XMPP Gateway The goal of this task is to implement a bidirectional signaling and media gateway for Presence, Instant Messaging, Multiparty IM, Audio, and File Transfer for SIP and XMPP signaling protocols, RTP and MSRP media planes. This research and development is part of the WormHole Project sponsored by "NLNet and AG Projects":http://nlnet.nl/project/xmpp-sip/. !http://sylkserver.com/images/sylk-server-diagram.png! h2. Deployment Scenario By pointing the correspondent DNS records for SIP or XMPP services of a given Internet domain to the address of this gateway, any packet sent to or connection established to the gateway by one of the protocols is transparently translated into the other. The server is designed in such way that it requires zero-configuration. h2. Specifications and Standards h3.
