In
2004 the introduction of VoIP services over broadband
Internet access services began changing the way consumers
viewed their phone and Internet service. The services
used a wide variety of forms which are more or less
similar to traditional POTS (plain old telephone service).
With VOIP services, your phone connects to the Internet over your cable or
DSL modem. To do this, Internet phone service providers bundle
a small device, called a telephony adapter, which plugs
into the broadband modem and translates the electrical
pulses from your phone into IP packets that travel over
the Internet. The way you use your phone is the same,
even though the network underneath changes.
When you choose a VoIP phone company you will still receive inbound and outbound calling with Direct Inbound Dialing. Many offer unlimited calling to the U.S. only, while others include Canada or selected countries in Europe or Asia as well, for a flat monthly fee.
