1.)SIP Messages
A SIP message is a simple text message that is similar to an HTTP message. It is either
a request from a client to a server, or a response from a server to a client.
Message Types
Following are the SIP message types:
• Request
• Response
The request and response messages use the same basic format.

2.)Dialog – All the messages that relate to the same session. For instance, all the messages that a Proxy Server must send out in response to a session request are part of the same dialog.
