Availability [edit]
SIP Witch is released as free software under the terms of version 3 or later of the GNU General Public License (GPL). It is designed for GNU/Linux, Mac OS X, BSD and Windows and planned support for Android.[1] In the popular GNU/Linux distributions Ubuntu and Fedora it may be installed directly from the standard package sources.[2][3]
Technology [edit]
SIP Witch is written in the programming language C++ and uses the uCommon,[4] eXosip[5] and GNU oSIP[6] libraries.
Features [edit]
The software enables Voice over IP as part of a self-organising Peer-to-peer telephone network.[1] It supports features like call forwarding, call distribution, call hold, presence information and (text) messages, supports encrypted calls and also enables NAT traversal to establish the peer-to-peer connections.[7]
History [edit]
The SIP Witch is being developed since the 10th of August 2007 by David Sugar within the GNU Telephony project. The first version was 0.1.0. Version 1 was released on May 14, 2011. It is being used as a component of GNU Free Call, which is supposed to be an alternative to Skype.[1]
