5 | 121 | Adrian Georgescu | PyPjUA is Python software library for [http://pjsip.org PJSIP] C SIP stack that together with a clever middleware allows for easy development of real-time communications end-points based on [http://tools.ietf.org/html/rfc3261 SIP protocol] with rich presence and IM capability that run on desktop computers running Mac OS X, Linux and Windows operating systems, portable devices like Nokia Internet tablet, Apple iPhone or Android mobile phone. |

7 | 14 | Adrian Georgescu | == Deliverables == |
8 | 1 | ||
9 | 128 | Adrian Georgescu | 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 adds both the to client and to the corresponding servers 'the missing' SIP-SIMPLE features for rich presence (Presence rules, Resource lists, RLS-services, RPIDF, XCAP full and partial document manipulation) and session based interactive messaging based on MSRP protocol including relay support. |
10 | 47 | Adrian Georgescu | |
11 | 130 | Adrian Georgescu | The software library is tested against the most popular SIP server software available today: [http://opensips.org OpenSIPS], [http://openxcap.org OpenXCAP] and [http://msrprelay.org MSRPRelay] servers. To test the software you can register a free SIP SIMPLE account on [http://SIP2SIP.info http://sip2sip.info]. PyPjUA is part of a [wiki:SIPUADesign greater design] design to provide a fully fledged SIP UA. |

15 | The software library and command line tools will be available for download on 2008 Q4. |

19 | 111 | Adrian Georgescu | == End-user experiences == |
20 | 1 | ||
21 | 123 | Adrian Georgescu | 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. |

23 | 123 | Adrian Georgescu | ''If you read them all some antidepressant and desintoxication is recommended after this effort.'' |
24 | |||
25 | 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: |
||
26 | |||
27 | 116 | Adrian Georgescu | * VoIP calls using Internet codecs (wide-band Speex, iLBC) and G.711 for compatibility with PSTN |
28 | * Multiple RTP streams per session (for live broadcasting applications) |
||
29 | * Session based IM with voice/video for rich end-to-end communications |
||
30 | 120 | Adrian Georgescu | * Zero configuration when communicating over LAN (Bonjour) |
31 | 1 | * Presence using SIP SIMPLE (PUBLISH, SUBSCRIBE, NOTIFY and XCAP policy) |
|
32 | 111 | Adrian Georgescu | * Interactive Messaging (IM) and File transfer using MSRP protocol |
33 | * Multiparty chat using MSRP chat server |
||
34 | 116 | Adrian Georgescu | * Support for NAT traversal using ICE for RTP media and MSRP relay for IM and file transfer |
35 | 111 | Adrian Georgescu | * Sharing desktop screen using VNC protocol |
36 | 92 | Ruud Klaver | * Video calls |
37 | |||
38 | 34 | Adrian Georgescu | == Software repository == |
39 | |||
40 | 88 | Adrian Georgescu | Besides the Python software library itself, the repository contains the ready to use sip-simple-test-tools package that can be used to: |
41 | 1 | ||
42 | 87 | Adrian Georgescu | * Setup SIP [http://tools.ietf.org/html/rfc4975 MSRP sessions] between end-points with public IP or behind NAT by using [http://tools.ietf.org/html/rfc4976 MSRP relay] |
43 | 117 | Adrian Georgescu | * Setup up VoIP sessions between end-points with public IP adresses or behind NAT by using ICE or MediaProxy |
44 | 34 | Adrian Georgescu | * [http://tools.ietf.org/html/rfc3903 PUBLISH] and [http://tools.ietf.org/html/rfc3265 SUBSCRIBE/NOTIFY to SIP events] like [http://tools.ietf.org/html/rfc3856 presence], [http://www.ietf.org/internet-drafts/draft-ietf-simple-xcap-diff-09.txt xcap-diff], [http://tools.ietf.org/html/rfc3857 watcher-info], [http://tools.ietf.org/html/rfc4575 conference], [http://tools.ietf.org/html/rfc3842 message-summary] |
45 | 112 | Adrian Georgescu | * Manage presence policy the form of full or partial [http://www.tools.ietf.org/html/rfc4825 XCAP] documents like [http://www.tools.ietf.org/html/rfc5025 pres-rules], [http://www.tools.ietf.org/html/rfc4826 resource-lists, rls-services] and [http://www.tools.ietf.org/html/rfc4827 pidf-manipulation] |
46 | * Lookup of SIP buddies using [http://www.tech-invite.com/SIPWGs/01-WG-SIP/Idrafts/draft-lee-sip-dns-sd-uri-02.txt Bonjour] (LAN broadcast), [http://tools.ietf.org/html/rfc3263 RFC 3263] (Locating SIP Services) and P2P overlays |
||
47 | 71 | Adrian Georgescu | * Setup up [http://www.tech-invite.com/SIPWGs/03-WG-SIMPLE/Drafts/draft-ietf-simple-chat-02.txt ad-hoc multi-party chat sessions] with an MSRP chat server (under construction) |
48 | 33 | Adrian Georgescu | * Alarms systems for SIP calls (VoIP sessions with RTP) |
49 | 103 | Adrian Georgescu | |
50 | 33 | Adrian Georgescu | Using these scripts is easy to prototype [wiki:RichPresence Rich Presence], IM and VoIP services based on the SIP protocol. |
51 | 103 | Adrian Georgescu | To use these tools you can use your own infrastructure or register a free SIP SIMPLE account on [http://sip2sip.info http://SIP2SIP.info] |

59 | 80 | Adrian Georgescu | PyPjUA will be first integrated into [http://tribler.org Tribler]. Tribler is an application that enables its users to find, enjoy and share content. With content we mean video, audio, pictures, and much more. PyPjUA will provides real-time communications features that will allow users that have downloaded Tribler to: |
60 | 62 | Adrian Georgescu | |
61 | 80 | Adrian Georgescu | * Interact in real time with each other using rich Presence, Interactive messaging and audio |
62 | 70 | Adrian Georgescu | * Communicate with other people that have access to SIP services from various SIP operators across the world |
