Learn about VoIP with this VoIP FAQ

For the past 50 years companies have been using conventional PBX & telephony systems which require separate networks for voice and data communications. But with the new VoIP telephony revolution, businesses are quickly migrating to VoIP PBX systems, which offer the huge advantage of converging data and voice networks.

VoIP, which stands for Voice over Internet Protocol, is basically the transmission of voice traffic over IP-based networks. Initially designed for data networking, the Internet Protocol (IP) was adapted to voice networking following its successful positioning as the global standard for data networking.

With VoIP phone systems users are not limited to making and receiving calls through the IP network. Traditional phone lines can be used to guarantee a higher call quality and availability. With the use of a VoIP gateway incoming PSTN/telephone lines can be converted to VoIP/SIP. The VoIP gateway allows the user to receive and place calls on the regular telephony network.

VoIP PBX systems provide mobility to employees, flexibility when a business expands as they are much easier to manage than the traditional PBX, and can also considerably reduce telephony administration costs.
