SIP brings us the next big step in Internet usage

Real-time person-to-person communication is the next big step of Internet usage. SIP (Session Initiation Protocol) is the Internet standard for such communication.

SIP is an Internet protocol for live communication between persons. It is a signalling protocol used for establishing sessions in an IP network. A session can be a simple two-way telephone call or it can be a collaborative multi-media conference session. The ability to establish these sessions means a host of innovative services become possible, such as instant messaging, presence, voice and video communication, data collaboration, application sharing, and much more.

Some of the features available with SIP communication.

Just like HTTP created the web and SMTP created email, SIP is creating the next big use of the Internet; real-time communication between persons. SIP is also the protocol of choice when making new IP telephony (VoIP - Voice over IP) installations, which is evidenced by its support from Microsoft, MCI, AT&T and many others.
