What is VoIP?
VoIP - Voice over Internet protocol. This is the technology used to transmit voice conversations over a data network using IP. This is done by digitizing voice into discrete packets that are transferred independently over the network, instead of traditional circuit-committed protocols of the PSTN.
How does VOIP work?
IP Phones - The IP phone looks much like a standard phone; it has buttons, a handset, and even a cradle. The difference is in its connectors, as it uses a RJ-45 Ethernet connector instead of the standard RJ-11 phone connector. The IP phone is hooked to the router on your computer. If you have a wireless connection, you can even purchase a Wi-Fi version of the phone which will allow you to make calls from any wireless “hot spot.”
Computer to Computer – This type of VOIP has numerous free and reasonably priced software available. By calling from computer to computer, you eliminate long distance charges.
Besides the required software, you’ll also need the following to make a computer-to-computer call: microphone, speakers, sound card, high speed Internet connection.
The better the quality of these items, the better the quality of your phone call will be.
Keep in mind that the person on the other computer must have software which is compatible with your own. If it’s not, then you’ll be unable to place a computer-to-computer call. This shouldn’t be a problem, however, as free software is available online and can be set up in under 10 minutes.
ATA - The ATA is known as an Analog Telephone Adaptor. A simple device, the ATA allows you to connect a regular telephone to your computer for the purpose of making calls. The analog signal from the phone is converted by the ATA into a digital signal and then transmitted.
