== Project description ==

PyPjUA is Python software library for [ PJSIP] C SIP stack that together with an elegant middleware allows for easy development of real-time Internet communications end-points based on [ SIP protocol] with Presence, IM and file transfer capabilities (SIP SIMPLE).

== Deliverables ==

The goal of this project is to deliver the best Open Source development kit 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 session based Interactive Messaging (IM) using MSRP protocol, multiple streams support, 'the missing' SIP-SIMPLE features for rich presence (presence rules, resource lists, RLS services, rich PIDF and XCAP policy).

The software library is tested against the most popular SIP server software available today: [ OpenSER], [ Asterisk], [ OpenXCAP], [ MSRPRelay] and [ MediaProxy].

== INSTALL procedure ==

The software has been tested on Linux Debian and MacOSX 10.5 (Leopard).

For people running Debian testing or unstable on an i386 architecture there is an official public repository provided by AG Projects. Install the AG Projects debian software signing key:

apt-key add agp-debian-gpg.key

Add the following lines to /etc/apt/sources.list

# AG Projects software
deb unstable main
deb-src unstable main

Update the list of available software:

apt-get update

Install the software:

apt-get install sipclient

For other distributions or the source code go to:

To obtain access to the version controlled software repository:

darcs get

== End-user experiences ==

The software allows you to create elegant real-time communications applications without having to read [ the +1200 RFC documents] behind it.

''If you read them all, some antidepressant and desintoxication is recommended after this effort.''

As a library with a high-level API, the toolkit can also be used to add SIP and Presence functionality to network devices without a display (like TV set-up boxes), as long as Python environment is supported by such platform. You may collapse the whole telecom industry into a simple ''Call me'' button or expand the presence buddy list to display the mood or blood pressure of your buddies (if they want to share this information with you). Some of the things possible with this library are listed here:

* VoIP calls using Internet codecs (wide-band Speex, iLBC) and G.711
* Zero configuration server-less communication over LAN (Bonjour)
* Parallel forking to multiple SIP devices
* Presence using SIP SIMPLE (PUBLISH, SUBSCRIBE, NOTIFY and XCAP policy)
* Interactive Messaging (IM) and File transfer using MSRP protocol
* Desktop sharing
* Video calls

== Testing the library ==

Besides the Python software library itself, the repository contains ready to use fully featured [wiki:testscripts command-line examples scripts] that can be used to:

* Register SIP end-points
* Setup up VoIP sessions
* Setup Interactive Messaging (IM) and file-transfer ([ MSRP sessions]) with or without support from a [ MSRP relay]
* Simulate SIP SIMPLE end-points: [ PUBLISH], SUBSCRIBE, NOTIFY for [ SIP events], presence data model and format ([ RFC3856], [ RFC3863 ], [ RFC4479]), [ xcap-diff], watcher-info ([ RFC3857],[ RFC3858] ), [ conference], [ message-summary]
* Manage [ XCAP] documents [ pres-rules], [ resource-lists, rls-services] and [ pidf-manipulation]
* Lookup of SIP buddies using [ Bonjour] (LAN broadcast), [ RFC 3263] (Locating SIP Services)
* Setup up [ ad-hoc multi-party chat sessions] with an MSRP chat server (under construction)

For testing, you can use your own infrastructure or register a free SIP SIMPLE account on []

== License ==

The software is provided under the [source:LICENSE GPL LICENSE]

== Contributing ==

We are looking for contributions related to DHT overlay (P2PSIP), desktop sharing, video sessions and real time text using RTP [ ToIP (RFC 4103)].
