SIP SIMPLE client is a Python software development kit that allows for easy development of Internet
communications end-points based on SIP and related protocols for voice,
rich presence, session based instant messaging (IM), file transfers and desktop sharing.
Other media types can be easily added by using an extensible high-level API.


SIP stands for 'Session Initiation Protocol', an IETF standard described by
[http://tools.ietf.org/html/rfc3261 RFC 3261]. SIP is an Internet application-layer control protocol that can establish,
modify and terminate multimedia sessions such as Internet telephony calls
(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
mutually understand like audio, video, instant messaging (IM), file transfer,
desktop sharing and provides a generic event notification system with
real-time publications and subscriptions about state changes that can be
used for asynchronous services like presence, message waiting indicator and
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.
