The goal of SIP SIMPLE client SDK is to provide a simple to use API to create Real Time Communications Applications for Internet end-points based on SIP and related protocols.

By using this SDK you can add Audio, Video, Instant Messaging, File Transfer and Desktop Sharing capabilities to an existing product or create a new product from scratch.

Prerequisites

To use SIP SIMPLE client SDK and the concepts described below you must be familiar with Python programming language and have basic knowledge of [http://www.tech-invite.com/Ti-sip-ex3261.html SIP protocol]. Good understanding of TCP/IP networking in general and experience with development of real time applications in particular is recommended.

Detailed instructions for installing the SDK are found [wiki:SipInstallation here].

Middleware API

To develop your SIP client Application you should use the Middleware API that hides the complexity and the interactions of the low level SIP, SDP, RTP, ICE, MSRP, XCAP protocols. With a minimal amount of coding you can create a rich client for setting up Audio, Instant Messaging, File Transfer and Desktop Sharing sessions.

Configuration API * [wiki:SipConfigurationAPI Configuration API] - manage the settings used by the Middleware and SIP Applications on top of it

=== Sample Code ===

  • [wiki:SipSessionExample Hello World!] - provides a minimalist example for setting up a Audio Session
  • [wiki:SipTesting Command Line Tools] provide detailed practical examples for how to use all functions available in the SDK
  • [http://icanblink.com Blink], a fully featured and easy to use SIP client or MacOSX

=== Components ===

If you wish to develop your own middleware or application while having full control over the underlying protocol layers yourself, you can use the following APIs that provide granular control over their respective components:

  • [wiki:SipCoreApiDocumentation SIP Core API] - SIP, RTP, ICE and Audio Engine including cross platform audio-device abstraction, codecs and jitter buffer
  • [wiki:SipMSRPApi MSRP API] - Message Session Relay Protocol (MSRP) and its Relay Extension
  • [wiki:SipPresenceApi Presence API] - Payloads carried within SIP signaling used for publication, subscription and notifications of SIP events
  • [wiki:SipXCAPApi XCAP API] - Manage presence policy documents on XCAP servers
