How VoIP IP Telephony Works?
FCC, Federal Communications Commission, states that "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."
Let's see how others describe it.
Howstuffworks tries to give you much information as possible with the article "How VoIP Works". I have gone through the complete article and found it to be ok. My writing ability is not as good as Robert Valdesz (It is getting there), otherwise I would try to write a simpler version as well.
He starts with how VoIP Works, How current PSTN, Public Switched Telephone Network, works which continues to the bits and bytes involved in a regular Telephone call, Advantages of VoIP, Disadvantages of VoIP and Codecs, softswitches and protocols.
All in all you get an idea of How VoIP Works but I wonder if the article ib being kept updated, for instance about E911, A lot has changed since it was written. So that is "How VoIP Works" until my writing improves. If I find any other VoIP introductions, I will Post them here.
