What is VoIP: Useful Terms. VoIP refers to a way to carry phone calls over an IP data network, whether on the Internet or your own internal network. A primary attraction of VoIP is its ability to help reduce expenses because telephone calls travel over the data network rather than the phone company's network.
VoIP solutions allow a dynamic interaction between users on any two domains on the Internet when a user wishes to place a call. To place calls via VoIP, a user will need a software based sip phone program OR a hardware based VoIP phone. Phone calls can be made to anywhere and to anyone: Both to VoIP numbers as well as PSTN phone numbers.
