Benefits of SIP
Session initiation protocol, commonly known as SIP is used for creating IP sessions in a network. The session could either be a collective multi-media session or a mutual telephone call. These sessions ensure that innovative services are possible, including voice enriched trading, Instant Messaging, and web page dialing.
1. Maximizes interoperability
Session initiation protocol is designed to bind existing applications and protocols, such as Web browsers and e-mail. Just like other internet applications, SIP focuses on a modular function, as well as specific design concepts.
2. Reusing protocols
Another feature that makes SIP popular is the fact that you can reuse existing design modules and protocol designs. For instance, SIP was designed after HTTP for SDP and addressing to convey information.
For the fast changing IP technology where many glitches are inevitable, flexibility is of utmost importance. SIP is a flexible approach, since it uses a number of protocol designs, each addressing specific needs. The philosophy behind using SIP sessions in a network is to compete with other technologies in the hopes of providing better solutions to emerging problems.
SIP is well-known for its simplicity, having been designed to establish several sessions, but is not familiar with the specifics of a particular session. Due to its simplicity, SIP is extensible and can allow you to comfortably work in different deployment scenario and different architectures with ease. Using SIP, integrating web applications with internet service has become easier than ever before.
5. Increasingly scalable
Unlike switched telephone networks, SIP integrates Instant Messaging apps including Apple iChat and MSN Messenger. Since SIP was specifically designed to solve problems on IP telephony protocols, the establishment of key function protocols has now become easier.
While SIP provides seamless communication between two end points, many find this approach impractical for public service.
