$Id$ Welcome to Kamailio v4.0! http://www.kamailio.org/ ========================== I. About Kamailio II. Feature List III. Getting started IV. About the project V. Obtaining Help VI. More Information Kamailio is an industrial-strength, free server for realtime communication, based on the Session Initiation Protocol (SIP RFC3261). It is engineered to power Realtime Communications such as IP telephony and presence infrastructures up to large scale. With embedded support for WebSockets, HTTP, MSRP and XMLrpc as well as Json-rpc it's a modern server, up to date with current standards. Kamailio keeps track of users, sets up multimedia sessions, relays instant messages and creates space for new plug-in applications. Its proven interoperability guarantees seamless integration with components from other vendors, eliminating the risk of a single-vendor trap. Kamailio has successfully participated in various interoperability tests in which it worked with the products of other leading SIP vendors. The Kamailio software enables a flexible plug-in model for new applications: Third parties can easily link their plug-ins with the server code and provide thereby advanced and customized services. With a modern RPC interface, 3rd party application can integrate and interact with services provided by Kamailio. Kamailio's performance and robustness allows it to serve millions of users and accommodate needs of very large operators. With a low-cost dual-CPU, the Kamailio server is able to power IP telephony services in an area as large as the Bay Area during peak hours. The Kamailio server is extremely configurable to allow the creation of various routing and admission policies as well as setting up new and customized services. Its configurability allows it to serve many roles: network security barrier, presence server, application server, IMS server or PSTN gateway guard (Session Border Controller) for example. II. Feature List ================ Please visit http://www.kamailio.org/ for the most up-to-date feature list. Note that as features easily are added as modules, changes can occur quickly. Most of Kamailio's features are implemented as plug-in modules. See our web site for a current list. III. Getting started ==================== The INSTALL document will guide you through the installation. Kamailio is composed of a core and additional modules. For each module there is a README with documentation on how to configure and use the module. These are available in each modules source code directory as well as on the kamailio.org web site. We recommend that you continue with reading README-MODULES and then the document named INSTALL. IV. About kamailio.org ======================== The Kamailio project has roots in a line of projects starting with SIP Express Router, then OpenSER and now Kamailio. A merge project was started during the fall of 2008 by developers from the OpenSER project, recently renamed to Kamailio.org and SIP Express Router (SER) from iptel.org. Kamailio is the result of a merge of the code base and years of experience from both developer teams. In release 4.0, during the spring of 2013, the merger of the products was completed and a unified product was released. See http://www.sip-router.org/ for the story of SER, OpenSER/Kamailio and kamailio.org. V. Obtaining Help ================= We offer best-effort free support for Kamailio.
