The Future of Telecommunications Belfast
The telecommunications network in Belfast is changing. The technology currently used to provide traditional landline voice calls (known as PSTN – Public Switched Telephone Network) is no longer fit for the future. Therefore, over the next few years, all landline phones will be replaced with a digital network, known as IP (Internet Protocol) network, also known as VoIP (Voice Over Internet Protocol).
While the traditional telephony system uses the circuit-switching method, VoIP uses the ‘packet switching’ method. This technology has been brought to the forefront of communications by the freedom and flexibility of the internet. The traditional ‘“copper wire” telephone network is to be made completely obsolete by 2025.
