From GNU Telephony
The GNU Free Call Project is offering a technological assistance package for common computing platforms. In the future we will provide support for multi-platform personal encryption and secure communications for both traditional and mobile platforms.
This initial 0.1 release only provides our switchview desktop client for use with GNU SIP Witch on your local machine.
All releases of tap are found at http://www.gnutelephony.org/dist/tarballs
The switchview client depends on and uses a locally installed instance of GNU SIP Witch.
