README / Sofia-SIP - RFC3261 compliant SIP User-Agent library
=============================================================

Introduction
------------

Sofia-SIP is an open-source SIP User-Agent library, compliant 
with the IETF RFC3261 specification. It can be used as 
a building block for SIP client software for uses such as VoIP, 
IM, and many other real-time and person-to-person communication 
services. The primary target platform for Sofia-SIP is 
GNU/Linux. Sofia-SIP is based on a SIP stack developed at 
the Nokia Research Center. Sofia-SIP is licensed under the LGPL.


Quick start
-----------

Sofia-SIP uses the GNU autotools, so building procedure
is the usual:

sh> sh autogen.sh (if building from darcs)
sh> ./configure
sh> make
sh> make install

See also 'docs/devel_platform_notes.txt' for notes on compiling
Sofia-SIP in different environments.

See the "options-client-example" (available using darcs at
http://sofia-sip.org/repos/options-client-example/ or with CVS as
a module in Sofia-SIP CVS tree) for an example of a small app that
is utilizing Sofia-SIP, and specifically the libsofia-sip-ua
library component.

There are also multiple example clients under
the "sofia-sip/utils" directory:

- sip-options, query using SIP OPTIONS method
- sip-date, SIP date printer/parser

The Sofia-SIP su submodule also provides some small utilities:

- addrinfo (libsofia-sip-ua/su), resolve host names 
- localinfo (libsofia-sip-ua/su), prints information about
  local network interfaces
