Describe how VoIP works?

Answer Posted / latha

Voice over Internet Protocol (VoIP), is a technology that
allows you to make voice calls using a broadband Internet
connection instead of a regular (or analog) phone line. Some
VoIP services may only allow you to call other people using
the same service, but others may allow you to call anyone
who has a telephone number - including local, long distance,
mobile, and international numbers. Also, while some VoIP
services only work over your computer or a special VoIP
phone, other services allow you to use a traditional phone
connected to a VoIP adapter.
