VoIP (voice over Internet protocol, also called Broadband Phone), offers the advantage of running both
voice and data communications over a single network which can represent a significant saving in
infrastructure costs.
VoIP solutions aimed at businesses have evolved into "unified communications" services that treat all
communications—phone calls, faxes, voice mail, e-mail, Web conferences and more—as discrete units that
can all be delivered via any means and to any handset, including cellphones.
