1 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Adrian Georgescu Founder and CEO of AG Projects Advocate of IETF standards (Internet Standards) Co-chair the Dutch ISOC SIP Special Interest Group Treasurer of OpenSIPS Software Foundation

2 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts SIP SIMPLE Client SDK

3 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts The project started with my dream to create an easy to use Real Time Communications software library

4 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Based on Open Standards related to SIP protocol

5 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts SIP protocol SIP stands for 'Session Initiation Protocol', an IETF standard described by RFC SIP is an Internet application-layer control protocol that can establish, modify and terminate multimedia sessions such as Internet telephony calls (VoIP). Media can be added to (and removed from) an existing session.

6 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts SIP is not for just for plain telephony replacement but also for other desirable forms of communication: HD Audio, Video, Instant Messaging and Desktop Sharing. SIP is a future-proof protocol, think about and www

7 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts I knew it was a difficult task

8 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts There are related standards today

9 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Most of all relevant Internet technologies are embedded into a real-time communication software

10 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Many have tried and many have failed to provide a future- proof solution

11 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Those who have tried and succeeded are walled-garden silos, they do not interoperate and are not using Open Standards

12 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts What does one need to create a compelling end-user experience for a SIP application?

13 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts First, it has to work!

14 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts For a SIP client to work, it needs good SIP server support with all relevant features

15 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts I started from my initial goal in 2003

16 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Building SIP servers

17 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts One learns a lot from building SIP servers, understands how SIP clients should behave

18 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts In 2008, we finished building several relevant SIP server components in use by many operators today

19 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts OpenSIPS - SIP Proxy/Registrar/Presence Agent MediaProxy - Relay for RTP media MSRPRelay - Relay for MSRP media OpenXCAP - Policy server for Presence CDRTool - Accounting and Mediation

20 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts We have created in this process what is AG Projects core business today, selling turnkey SIP infrastructure

21 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts We gained the necessary experience required for building the SIP client

22 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts With this experience, we secured the necessary funding from an EU project in late 2007

23 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts We started building the foundation for a generic SIP client in early We are now 90% done after 2 years of development

24 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts SIP SIMPLE client SDK

25 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts SIP SIMPLE client SDK SIP SIMPLE client SDK is a Software Development Kit for development of Real Time Applications based on SIP and related protocols for media transport like Presence, Audio and Instant Messaging (IM). Other media types can be easily added by using an extensible high-level API. The software has undergone in the past years several interoperability tests at SIPIT and today is of industry strength quality.

26 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts SIP SIMPLE client SDK The library has cross platform capabilities on Linux OS, Mac OSX, Microsoft Windows is on the roadmap. The library should work with minimal changes on any platform that supports C and Python development environments.

27 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Generic Features Written in Python Programming Language Non-blocking and Asynchronous High Level Middleware with Configuration Framework TLS Security for signaling (SIP) and media (MSRP, XCAP) Multiple Media Types per Session (e.g. Audio + IM) Trace capability for all underlying protocols Supports re-INVITE for adding and removing media Audio Conference Bridge Wav Player and Recorder Acoustic Echo Cancelation Answering Machine with take over support Wide-band Internet codecs: Speex and G722 PSTN compatible codecs: G711, iLBC, GSM

28 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts SIP Signaling Session Initiation Protocol RFC3261 Session Description Protocol RFC4566 An Offer/Answer Model with Session Description Protocol (SDP) RFC4566

29 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Location Discovery RFC3263 next hop resolution lookup Bonjour multicast DNS (work in progress

30 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts NAT Traversal SIP Signaling: Symmetric Response Routing Symmetric media RFC3581 RTP media (Audio and Video): Interactive Connectivity Establishment (ICE) draft-ietf- mmusic-ice-19 MSRP media (Instant Messaging and File Transfers): MSRP Protocol Relay Extension RFC4976

31 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Voice and Video over IP RTP, A Transport Protocol for Real-Time Applications RFC3550 Real Time Control Protocol (RTCP) attribute in Session Description Protocol (SDP) RFC3605 The Secure Real-time Transport Protocol (SRTP) RFC3711 Generation and parsing of RFC 2833/telephone-events payload in both RTP and SDP RFC283

32 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Multi-party Conferencing Conference Event Package RFC4575 A Framework for Conferencing with the Session Initiation Protocol RFC4353 (work in progress) SIP Call Control - Conferencing for User Agents RFC4579 (work in progress) MSRP ad-hoc multi-party chat sessions draft-ietf-simple-chat-05 (work in progress)

33 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Instant Messaging Common Presence and Instant Messaging (CPIM): RFC 3862 Session Initiation Protocol (SIP) Extension for Instant Messaging RFC3428 MSRP Protocol RFC4975 Indication of Message Composition for Instant Messaging RFC3994 Message Summary Event Package RFC3842 File Transfer RFC5547 Desktop Sharing: Variation of draft-garcia-mmusic-sdp-collaboration-00 using RFB over MSRP

34 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Presence SIP Specific Event Notification RFC3265 SIP Extension for Event State Publication RFC3903 Presence Data Model (PIDF) RFC3863, RFC3379, RFC4479 Watcher-info Event Package RFC3857, RFC3858 Rich Presence Extensions to PIDF RFC4480 Contact Information Extension to PIDF RFC4482 User Agent Capability Extension to PIDF RFC5196 XCAP Protocol RFC4825 Common Policy RFC4745 Presence Rules RFC5025 Resource Lists RFC4826 RLS Services RFC4826 PIDF manipulation RFC4827

35 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts

36 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Having the foundation in place, we went back to the design a Graphical User Interface SIP client

37 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts We secured the funding from AG Projects and NLNet Foundation

38 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts The key was simplicity and desirability

39 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts My father should be able to use it

40 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts My wife should find pleasure in using it

41 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts My son should be proud his father did it

42 AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Welcome to Blink !
