| SIP is Session Initiation Protocol, and is a form of VOIP. It is used as a digital voice emulator/PRI replacment. It gives VOIP service more capabilities, such as DID's (Direct Inward Dial numbers) The benefit of this service on the commercial level is the ability to avoid buying a PRI card (down the road--not right now in all cases) and just plug straight into the phone system. Essentially, the power of PRI without the cost or limitations. SIP is only limited by your bandwidth, and carriers are coming up with some pretty interesting options. this will be an area that many will need to become more familiar with, especially in the call center world. |
