Summary
DescriptionSIP session setup example.svg
English: Diagram shows a typical example of a SIP message exchange between two users, Alice and Bob. In this example, Alice uses a SIP application on her PC (referred to as a softphone) to call Bob on his SIP phone over the Internet. Also shown are two SIP proxy servers that act on behalf of Alice and Bob to facilitate the session establishment. This typical arrangement is often referred to as the "SIP trapezoid". --RFC 3261: "SIP: Session Initiation Protocol" (2002)
