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

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

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

AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts SIP protocol SIP stands for 'Session Initiation Protocol', an IETF standard described by RFC 3261. SIP is an Internet application-layer control protocol that can establish, modify and terminate multimedia sessions such as Internet telephony calls (Vo. IP). Media can be added to (and removed from) an existing session.

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 email and www

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

AG Projects The SIP Infrastructure Experts There are +1200 related standards today SIP SIMPLE client SDK

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

AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts Many have tried and many have failed to provide a futureproof solution

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

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?

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

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

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

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

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

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

AG Projects The SIP Infrastructure Experts Open. SIPS - SIP Proxy/Registrar/Presence Agent Media. Proxy - Relay for RTP media MSRPRelay - Relay for MSRP media Open. XCAP - Policy server for Presence CDRTool - Accounting and Mediation SIP SIMPLE client SDK

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

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

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

AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts We started building the foundation for a generic SIP client in early 2008. We are now 90% done after 2 years of development

AG Projects SIP SIMPLE client SDK The SIP Infrastructure Experts 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.

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.

AG Projects 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 G 722 PSTN compatible codecs: G 711, i.
