How does VoIP work? Voice over IP explained.

First, voice is converted by an ATA (Analog Telephone Adapter) or IP phone, from an analog signal to a digital signal.  It is then sent over the Internet in data packets to a location that will be close to the destination.  Then it will be converted back to an analog signal for the remaining distance over a traditional circuit switch (PSTN) (unless it is VoIP to VoIP).  Your call can be received by traditional telephones worldwide, as well as other VoIP users.

VoIP to VoIP calls can travel entirely over the Internet.  Since your voice is changed to digital (so that it can travel over the Internet), other great features such as voice messages to email, call forwarding, logs of incoming and outgoing calls, caller ID, etc., can be included in your basic calling plan all for one low price. Many of these special features are great for the small business person who relies on their phone service to be more a information center rather than just a telephone.
