Understanding Voice Over Internet Protocol (voip).
Christine Hancock
Internet Voice, also known as Voice over Internet Protocol (VoIP), is a technology that allows you to make telephone calls using a broadband Internet connection instead of a regular (or analog) phone line. Some services using VoIP 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 services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone through an adaptor. The calls are made over a data network like the internet. VoIP converts the voice to a digital signal that can travel over the internet then converts it back to voice once it reaches the other end. This enables you to speak to anyone with a regular phone number. When placing a VoIP call using a phone with an adapter, you'll hear a dial tone and dial just as you always have. VoIP may also allow you to make a call directly from a computer using a conventional telephone or a microphone.
Placing a Call
All VoIP Services are a bit different in the way you place a call. If you have an adapter connected to your internet Connection you can-just pick up your phone and dial the number. The call goes through your local phone company to a VoIP provider. The call proceeds over the internet to the called party's local telephone company and the call is completed. You can also plug a microphone headset into your computer, this is a good option it you have a slow (dial-up) connection as it cuts out some of the echo commonly heard in slow connections. Utilizing a headset, the number is dialed using a keyboard & routed through your cable modem.
