SIP

Session Initiation Protocol, SIP is a new Internet protocol that has rapidly become very popular. SIP is used to set up a session between users and this is the most exciting protocol for new applications on the Internet today. It is a protocol that enables peer-to-peer sessions to be initiated between users. This is in contrast to most protocols today, which handle communication between a PC (a client) and a server. Examples of services that use SIP are IP telephony, presence and instant messaging and videoconferences.
