The UK’s telephone system will be upgraded by using the internet to make calls rather than via the old copper network. For most, the changeover will be straightforward as telecoms providers will automatically make the switch for them.
However, the exact migration process will depend on your telecoms provider and the equipment they use. Landline users should be contacted ahead of the switch, and you do not need to take any action beforehand. If you are a vulnerable customer, or you use your telephone line for alarm systems, fax machines or telecare devices, you may need to carry out additional steps which can be supported via your telephone provider.
While the move should be simple, there are a few implications of switching to a digital-only landline. The traditional copper landline continues to work during a power cut due to drawing power from the exchange. But with VoIP, users will be unable to use their landline unless they have a battery back-up. Mobile phones will, of course, be unaffected.
If you do not have a mobile phone or mobile reception in your area, your telecoms provider should give you a spare battery pack, so you’re not cut off when you need service the most.
