What is VoIP?

The IP telephony, known as VoIP (Voice over IP), is a technology that has and still is changing the way that people communicate and relate to each other. It's key benefit is the extremely low cost compared to the classic telephony.
The"Voice Over Internet Protocol" technology allows for calls to be made between two people, of which at least one must have a dedicated/temporary Internet connection. Because this technology uses the Internet to relay the calls, and not the conventional circuit-switched method, the rates are a few times lower compared to the traditional telephony systems. A call can be made using a PC connected to the Internet or a VoIP hardware device.
In this case, the caller uses a PC or a telephone connected to a Voice/IP conversion device, and the callee answers using a regular telephone. The voice signal travels most of its way in the form of H.323 IP packets routed through the Internet. These packets are then turned back into voice signal and inserted into the telephone network using a device called "Gateway". At the two ends of a VoIP connections one can install computers, telephones, VoIP hardware equipment or fax machines in any combination. In order to connect to our voice network (VoIPNet), the purchase/rental of a SIP-compliant device that converts the voice signal from either a regular phone or a PBX switching center into IP packets is needed. We use and recommend the use of Cisco equipment, which we believe ensures the best quality at a reasonable price.
