Digital and VOIP Telephone Services
VoIP phone service (Voice over IP; also known as digital phone service, digital telephony, or broadband phone) replaces your phone line with a high-speed Internet connection.
While traditional telephone systems compress your voice on a wire, VoIP compresses the sound of your voice into packets of data. In milliseconds, these data packets are sent over the Internet. When the data reaches the final destination, it is converted back to sound. If use VoIP to call someone on the traditional phone network (the “PSTN” or Public Switched Telephone Network), the VoIP call is converted to sound once it reaches the network and the call is routed normally. The difference is that you’ve paid a lot less for that call.
