Chapter 5 SIP Configuration
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
(IETF) standard for multimedia conferencing over IP, described in RFC 3261. 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, and
• Redirect Server.
This section describes the SIP User Agent and the call establishment between User Agents.
