SIP Witch is written in the programming language C++ and uses the uCommon,[4] eXosip[5] and GNU oSIP[6] libraries.

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]
