*The SIP Protocol*

To make all that possible, GNU Free Call will use the Session Initiation
Protocol <http://en.wikipedia.org/wiki/Session_Initiation_Protocol> (SIP),
an Application Layer signaling protocol that's designed to be independent of
the underlying transport layer.

Specifically, it will build upon the existing GNU SIP
Witch<http://www.gnu.org/software/sipwitch/>VoIP server, which
operates without introducing a central point through
which communications can be intercepted or captured. GNU SIP Witch also
requires minimal system resources, making it suitable even for low-end
embedded routers.

GNU SIP Witch is already packaged in a number of popular Linux
distributions, including
Ubuntu<http://www.pcworld.com/businesscenter/article/221517/work_begins_on_ubuntu_1110_oneiric_ocelot.html>and
Fedora, but it can also be built on most BSD systems from source, and
it
supports compilation on Microsoft
Windows<http://www.pcworld.com/businesscenter/article/207196/why_windows_is_bad_for_business.html>as
well, according to the GNU Free Call project.

"We will extend SIP Witch to become aware of peer nodes by supporting host
caches, and then support publishing of routes to connected peers," the
project explains. Host caches are a mechanism used in older P2P networks and
are easy to implement, it adds.
