Description

[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:

[[Image(htdocs:SIPSIMPLE-client.png, align=right, nolink)]]
SIP SIMPLE client is Python software library built on top of [http://pjsip.org PJSIP] that together
with an elegant middleware allows for easy development of Client/Server and
Peer-to-Peer Internet communications end-points based on SIP SIMPLE protocols with
voice, video, presence, interactive messaging (IM) and file transfer capabilities.

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

Download and installation

For Debian testing or unstable on an i386 architecture, add to /etc/apt/sources.list:

{{{
deb http://ag-projects.com/debian unstable main
deb-src http://ag-projects.com/debian unstable main
}}}

Update the list of available software and install the software:

{{{
apt-get update
apt-get install sipclient
}}}

For MacOSX 10.5 (Leopard) on an Intel architecture add to /sw/etc/apt/sources.list:

{{{
deb http://ag-projects.com/fink local main
deb http://ag-projects.com/fink stable main crypto
deb http://ag-projects.com/fink unstable main crypto
}}}

Update the list of available software and install the software:

{{{
sudo apt-get update
sudo apt-get install sipclient
}}}

Step by step installation instructions are available in [source:docs/INSTALL.linux INSTALL.linux] and [source:docs/INSTALL.osx INSTALL.osx]. For other operating systems or to obtain the full source code as tar archive go to:

[http://download.ag-projects.com/SipClient/ http://download.ag-projects.com/SipClient/]

Windows binaries are on the roadmap.

Testing the library

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 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.

  • [wiki:sip_register sip_register] - REGISTER a SIP end-point with a SIP Registrar
  • [wiki:sip_rtp_audio_session sip_rtp_audio_session] - Setup a voice audio session (Voice over IP)
  • [wiki:sip_msrp_im_session sip_msrp_im_session] - Setup an IM session using MSRP protocol
  • [wiki:sip_msrp_file_transfer sip_msrp_file_transfer] - Perform file transfer using MSRP protocol
  • [wiki:sip_message sip_message] - Send/receive text in page mode using SIP MESSAGE method
  • [wiki:sip_publish_presence sip_publish_presence] - PUBLISH presence to a SIP Presence Agent
  • [wiki:sip_subscribe_presence sip_subscribe_presence] - SUBSCRIBE to presence information
  • [wiki:sip_subscribe_winfo sip_subscribe_winfo] - SUBSCRIBE to watcher list on a SIP Presence Agent
  • [wiki:sip_subscribe_rls sip_subscribe_rls] - SUBSCRIBE to lists managed by Resource List Server
  • [wiki:xcapclient xcapclient] - PUT/GET/DELETE full or partial documents on an XCAP server
  • [wiki:xcap_pres_rules xcap_pres_rules] - Manage entries in the pres-rules XCAP document
Supported platforms

As a library with a high-level API, the toolkit can be used to add voice, IM and Presence functionality to any Internet device as long as Python/C environment is supported by such platform.
