VoIP stands for Voice over Internet Protocol (sometimes referred to as “Internet telephony,” “Voice over IP,” or “IP telephony”). Enterprise VoIP technology allows voice signals to be transmitted over the Internet rather than how traditional telephone systems did it, through landlines.

Instead of working off the Public Switched Telephone Network (PSTN) and using landlines, all VoIP requires is a broadband connection. You know how when phone lines go down, an entire city or state might experience an outage? That doesn’t happen with VoIP.
