[http://www.tech-invite.com/Ti-sip-IDs-SIMPLE.html#charter SIP SIMPLE] client is a SIMPLE SIP client. Which leads to the question how SIMPLE is [http://www.tech-invite.com/Ti-sip-IDs-SIMPLE.html#charter SIMPLE]. So let's try again:

SIP SIMPLE client is Python software library built on top of [http://pjsip.org PJSIP] that together
7 199 Adrian Georgescu
with an elegant middleware allows for easy development of Client/Server and
8 1
Peer-to-Peer Internet communications end-points based on SIP SIMPLE protocols with
9 1
voice, video, presence, interactive messaging (IM) and file transfer capabilities.

The goal of this project is to deliver the best Open Source Python
12 193 Adrian Georgescu
library for rich featured SIP User Agents, while hiding the complex
13 187 Adrian Georgescu
underlying functionality behind an easy to use high-level application
14 187 Adrian Georgescu
programming interface. Compared to other available SIP libraries, this
15 239 Adrian Georgescu
project provides beyond basic audio calls, session based Interactive  Messaging (IM) 
16 239 Adrian Georgescu
combined with voice and video sessions, file transfer and multi-party chat sessions using MSRP protocol, 
17 220 Adrian Georgescu
publication and subscription for rich presence information like availability, moods, activities and geo-location, management for presence rules, 
18 267 Adrian Georgescu
resource lists, RLS services using XCAP protocol.

Another way to put it, 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. If you read them all, some antidepressant and desintoxication is recommended after this effort.

Once completed, you will be able to use its functionality in your favorite UNIX console, embed it into a networked device or create a skinable GUI for it on your favourite OS in no time.

SIP SIMPLE client is closely developed together with and tested against the most popular SIP SIMPLE server software available today: [http://opensips.org OpenSIPs], [http://openxcap.org OpenXCAP] and [http://msrprelay.org MSRPRelay]. Included with the library, a set of [wiki:testscripts command line tools] are available for setting up real time voice, IM and file transfer sessions, publish and subscribe to presence or other type of events:
