HowTo use the sipXtapi SDK
The sipXtapi SDK is a C application programming interface for voice communications over IP. Specifically, sipXtapi provides a generalized telephony interface on top of the Session Initiation Protocol (SIP), RFC 3261, and the real-time Transport Protocol (RTP), RFC 1889. While the SIP and RTP protocols provide signaling and media transport infrastructure, sipXtapi also includes many other protocol and standards implementations needed for voice communications.
sipXtapi is developed under open source and hosted as part of the sipX line of projects available from SIPfoundry. It is licensed under LGPL which allows commercial usage of the library without the �viral infection� associated with GPL. Essentially, you may use the code as-is and build on top of it without exception, however, if you modify the existing code (e.g. bug fix), you must make changes available under LGPL. For more information on open source licensing or SIPfoundry, please see www.opensource.org or www.sipfoundry.org.
