GNU SIP Witch is a telephony server that focuses on secure enabling peer to peer media connections. GNU SIP Witch avoids centralized decryption and minimizes overhead by eliminating the need for media processing. This also enables Video capable endpoints to communicate without requiring server support and eliminates the need for using patent restricted media codecs. Releases of GNU SIP Witch can be found at http://ftp.gnu.org/gnu/sipwitch/.
Version 0.5.6 - June 2009 This release introduces new transitional support for network origin and peering detection of endpoints for what will be the 0.6 release series. This enables sipwitch to determine what subnet a peer is communicating from, and where the interface address of sipwitch, whether local or external (public side of NAT) appears in reference to that user agent. With this information we can now automatically classify when and where RTP media proxy assistance is needed between two endpoints, such as for NAT penetration when one or more endpoints are behind NAT. Introduction of refer method call transfer was also added. We are looking for help with packaging for inclusion in different free software distributions, and with further testing of secure distributed key VoIP solutions built around sipwitch, the GNU ZRTP stack, and secure user agents such as Twinkle and SIP Communicator. _______________________________________________ GNU Announcement mailing list <info-gnu@gnu.org> http://lists.gnu.org/mailman/listinfo/info-gnu
