The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. It can be used to create two-party, multiparty, or multicast sessions that include Internet telephone calls, multimedia distribution, and multimedia conferences. It is basically the protocol that many VOIP providers use to start/stop a call. For more information check... http://en.wikipedia.org/wiki/Session_Initiation_Protocol

In simple terms: SIP is just a protocol that's used to setup and tear down an internet based phone call. VoIP uses SIP for example. Traditional setup and tear down of phone calls over a land-line is called SS7.
