What is a VOIP number?
VOIP stands for "voice over IP" and a VOIP number essentially allows for voice communication to occur over an IP network. Typically, VOIP numbers allow for phone calls to be placed/received through a computer, although these numbers can also be associated with "plug and play" devices such as an IP phone.
