| 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. |
