11.1.3.2 SIP Service Domain
The SIP service domain of the VoIP service provider (the company that lets you make phone
calls over the Internet) is the domain name in a SIP URI. For example, if the SIP address is
, then “VoIP-provider.com” is the SIP service domain.
11.1.4 SIP Call Progression
The following figure displays the basic steps in the setup and tear down of a SIP call. A calls
B.
A sends a SIP INVITE request to B. This message is an invitation for B to participate in a SIP
telephone call.

B sends a response indicating that the telephone is ringing.
7
B sends an OK response after the call is answered.
8
A then sends an ACK message to acknowledge that B has answered the call.
9
Now A and B exchange voice media (talk).
10
After talking, A hangs up and sends a BYE request.
11
B replies with an OK response confirming receipt of the BYE request and the call is
terminated.
11.1.5 SIP Client Server
SIP is a client-server protocol. A SIP client is an application program or device that sends SIP
requests. A SIP server responds to the SIP requests.
When you use SIP to make a VoIP call, it originates at a client and terminates at a server. A
SIP client could be a computer or a SIP phone. One device can act as both a SIP client and a
SIP server.
