Project description

PyPjUA is Python software library for [http://pjsip.org PJSIP] C SIP stack that together with an middleware allows for easy development of SIP User agents that run on desktop computers running Mac OS X, Linux and Windows operating systems, portable Internet devices like Nokia 810, Apple iPone or Android mobile phones.

License

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

Deliverables

The goal of this project is to deliver an Open Source development kit for a rich featured SIP User Agent while hiding the complex underlying functionality behind an easy to use high-level application programming interface. You may collapse the whole telecom industry into a ''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).

Using this software you are able to create elegant real-time communications applications without having to read or understand [http://www.rfc3261.net the +1200 RFC documents] behind it. ''If you read them some antidepressant and some des-intoxication is recommended after this effort.''

Software repository

Besides the Python software library the software contains ready to use test scripts for:

  • Publishing and subscribing to SIP events like presence, xcap-diff, watcher-info, conference, message-summary
  • Lookup destinations using Bonjour, RFC 3263, ENUM, STUN and P2P overlays
  • Managing full or partial XCAP documents like pres-rules, resource-lists and pidf-manipulation
  • Setting up SIP MSRP sessions between end-points with public IP or behind NAT
  • Setting up ad-hoc multi-party chat sessions with an MSRP chat server
  • Setting up VoIP sessions between end-points with public IP adresses or behind NAT

Using these scripts is easy to prototype Presence, IM and VoIP services based on the SIP protocol.

Download

The software can be downloaded from:

End-user experiences

Using this toolkit you can develop in short time a skinable and cross-platform SIP User Agent that can be used for real-time Internet communications:

  • VoIP calls using Internet codecs (Speex, iLBC)
  • Presence using SIP SIMPLE (PUBLISH method and XCAP policy)
  • Interactive Messaging (IM) and File transfer using MSRP protocol
  • Multiparty chat using MSRP chat server
  • Support for NAT traversal using ICE for RTP media and MSRP Relay for IM
  • Sharing desktop screen using VLC protocol
  • Video calls

The software is tested against most popular SIP server software including [http://openser.org OpenSER], [http://openxcap.org OpenXCAP], [http://mediaproxy-ng.org MediaProxy] and [http://msrprelay.org MSRPRelay] servers.
