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].

Status

The software is in active development and progress announcements will be made on the mailing list http://lists.ag-projects.com/mailman/listinfo/sipbeyondvoip

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.
