''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 SIP stack is provided by [http://www.pjsip.org PJSIP].

The library has cross platform capabilities on Linux OS, Mac OSX (Leopard and Snow Leopard) and Microsoft Windows (roadmap). The library should work with minimal changes on any platform that supports C and Python development environments.

The library uses a separated from the core lookup mechanism for the next hop routing. This important feature allows the library to be used for building SIP clients that operate in combination with any SIP provider (by employing RFC 3263 DNS lookups), in a server-less LAN operation (using Bonjour protocol) or integrated into a network overlay developed by a third party (e.g. P2PSIP overlay).
