Popular VoIP phone services. Reviews of IP telephony providers.
VoIP telephony (Voice over IP telephony) is the practice of using an Internet connection to pass voice data using IP instead of using the standard public switched telephone network.
This allows a remote worker to function as if he were directly connected to a PBX even while at home or in a remote office.
It skips standard long distance charges, as the only connection is through an ISP.
VoIP telephony is being used more and more to keep telephone costs down.
