SIP SIMPLE client is a Python software library that allows for easy development of Internet
7 378 Adrian Georgescu
communications end-points based on SIP and related protocols for voice,

SIP stands for 'Session Initiation Protocol', an IETF standard described by
14 382 Adrian Georgescu
[http://tools.ietf.org/html/rfc3261 RFC 3261]. SIP is an Internet application-layer control protocol that can establish,
15 346 Adrian Georgescu
modify and terminate multimedia sessions such as Internet telephony calls
16 346 Adrian Georgescu
(VoIP). Media can be added to (and removed from) an existing session.

SIP allows the endpoints to negotiate and combine any type of session they
19 383 Adrian Georgescu
mutually understand like audio, video, instant messaging (IM), file transfer,
20 346 Adrian Georgescu
desktop sharing and provides a generic event notification system with
21 346 Adrian Georgescu
real-time publications and subscriptions about state changes that can be
22 346 Adrian Georgescu
used for asynchronous services like presence, message waiting indicator and
23 346 Adrian Georgescu
busy line appearance.

The software allows you to create elegant real-time communications applications without having to read [http://www.rfc3261.net the +1200 RFC documents] behind it. As a library with a high-level API, the toolkit can be used to add voice, IM and Presence functionality to any network devices as long as Python/C environment is supported by such platform.
