Voice over Internet Protocol (VoIP)

The University of Delaware uses Voice over Internet Protocol, or VoIP, for its telephone service. VoIP provides the same services as older telephone service technology, including 4-digit dialing and voice mailboxes as well as additional services such as free nationwide long-distance calling.

Because VoIP transmits phone calls over a data network along with computing data traffic, VoIP offers a sustainable phone service over one network—with no change in line cost.
