SIP explained

This article contains important information about the SIP (Session Initiation Protocol) which is a signaling protocol used for creating and terminating sessions. You will be familiar with the basics in relation with the protocol like what can SIP be used for and why it is needed for communication.

A protocol is a set of rules. It describes the transmission of data between two computers (how the data can be transmitted).

The SIP protocol establishes connection over the Internet. So when there is a request for a communication process, the protocol builds up a channel between two computers and when the communication ends, the SIP protocol terminates the call (Figure 1).

SIP Phones and Communication Systems

Session Initiation Protocol is primarily applied by businesses to build up communication based on the Internet. A communication endpoint can be a computer. The endpoint should be equipped with different devices such as a microphone, a loudspeaker or a headset in order to make both video and voice calls and other devices can be endpoints too, like iPhones, smartphones, tablet PCs (personal computers) and PDAs (Personal Digital Assistants). The devices mentioned above can be SIP phones if the devices have the proper application installed on them.
