SIP Stack
Session Initiation Protocol (SIP) is a protocol developed by the IETF MMUSIC working team. It was proposed as a standard for establishing, modifying and terminating interactive user sessions, including various multimedia such as video, audio, instant messaging, online games and virtual reality. SIP has officially been approved as one of 3GPP signaling protocols and a permanent unit of IMS architecture. (From Wikipedia)
Why choose SIP?
Readability
SIP is expressed in the form of text. Its syntax is easy to understand and the semantics is close to human natural language. Hence, as a communication signaling protocol, SIP is very conducive to communication whether for development, debugging, or interoperability test.
Scalability
RFC3261, among which are documents defined by the IETF, OMA, GSMA and 3GPP Organizations. And thus various types of business expand. SIP has no restriction in communication carrier and can build any SIP protocol structure boasts of strong scalability. So far, there are hundreds of extension protocol based on the SIP core of Protocol.
 
Collaboration
SIP can work together with many other protocols to provide more powerful business capability. It includes SDP,DHCP, HTTP、DNS, RADIUS, XCAP, TBCP, MSRP, etc. What’s more, it can even work with the protocols that you defined.
Popular
SIP is getting more and more popular. Apart from the traditional application of VoIP, SIP is also adopted as the main protocol in IMS architecture, the application system of IP domain in 3G and 4G LTE and the network operator area. SIP protocol is broadly used by the Internet and IT vendors. Some of the examples are Microsoft, Apple and AOL.
