MERSEYSIDER Mick Clarke who runs Digital Exchange Products (DXP) explains how telecommunication services are evolving.
“Internet telephony, or VoIP (Voice over internet Protocol) comes in various guises, but is all based on the same technology. As we see a migration from analogue or digital telephony, to IP telephony, the traditional telephone system or telephone exchange may become a thing of the past. In fact BT’s introduction of 21CN (21st Century Network) is basically the replacement of the existing network to an IP based network, where voice and data calls are sent as packets, rather than transmitted in the standard method.”
