What is VoIP? Voice over Internet Protocol is the ability to make and receive voice phone calls over an IP based network. This includes a Local Area Network and a public IP network such as the Internet. The technology has been around for many years but mostly at big business level who used their large network capacity to also carry voice phone calls.
The Gateway receives voice and data services over a single network connection. Expensive long-distance and international phone calls over the ordinary telephone service can be avoided altogether. You make and receive voice calls over the same line that you use to connect to the Internet, and pay the same Internet connection charge, plus a service charge to your Service Provider.
You simply plug in any ordinary telephone sets to the phone sockets on the Gateway, then operate your telephone as you normally do. All destination numbers must be registered with your Internet Telephony Service Provider or Proxy Server. You dial your server's code, then your destination number; the Internet Telephony Service Provider or Proxy Server will map your number with the destination. The Gateway incorporates Quality of Service (QoS) functions to ensure that voice received is almost the same as that received on the ordinary phone. To allow for a smooth voice reception, voice packets get a higher priority over data packets on the network packet stream. Other capabilities include echo cancellation, silence suppression/comfort noise generation (when there is a prolonged silence), adaptive jitter buffer and lost voice packet recovery. Features
