 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.
+It is engineered to power Realtime Communications such as IP telephony and
+presence infrastructures up to large scale. With embedded support for
+WebSockets/WebRTC, HTTP, XSRP and XMLrpc as well as Json-rpc it's a modern
+server, up to date with current standards on IPv4/IPv6 and TLS security.
 
 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. By using the EVAPI interface or the
-embedded HTTP server restful applications can be built.
-
-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.
