Chapter 6 SIP SIP, the Session Initiation Protocol, is a signaling protocol for Internet conferencing, telephony, presence,
events notification, and instant messaging. It is the Internet Engineering Task Force's (IETF's) standard
for multimedia conferencing over IP. It is designed to address the functions of signaling and session
management within a packet telephony network. Signaling allows call information to be carried across
network boundaries. Session management provides the ability to control the attributes of an end-to-end
call.
Session Initiation Protocol is a peer-to-peer protocol. There are four components in the SIP standard:
User Agent (UA)
Proxy Server
Registrar Server
Redirect Server
