Session Initiation Protocol (SIP): Locating SIP Servers
The Session Initiation Protocol (SIP) uses DNS procedures to allow a client to resolve a SIP Uniform Resource Identifier (URI) into the IP address, port, and transport protocol of the next hop to contact. It also uses DNS to allow a server to send a response to a backup client if the primary client has failed. This document describes those DNS procedures in detail.

Deploying SIP Applications
This flexible and easy-to-use protocol is used for establishing sessions, usually in an IP network. Sessions range from multimedia conferencing to content services such as Internet telephone call and multimedia distribution. SIP is a request-response protocol that closely resembles the Hypertext Transfer Protocol (HTTP), which forms the basis of the World Wide Web. It re-uses many of the constructs and concepts of Internet protocols such as HTTP and Simple Mail Transfer Protocol (SMTP).
