BT announced in 2015 that they will be switching off the PSTN and ISDN copper phones lines in 2025! By then, every phone line in the United Kingdom will be routing it's calls through the Internet, instead of the old (PSTN) copper wires.

Any device, be it your landline handsets, fax machines, building and social care alarm systems, point-of-sale card machinery etc, that still use the copper wire (PSTN) connection... will cease to work and this may happen or develop issues way before the official 2025 switch off!

Qdos can help your business get ready by moving your company to a digital system, where you'll benefit from superior features, flexibility, unified communications and unparalleled mobility at far lower cost than traditional phone systems.
