Digital Phone Line Upgrade

Openreach are upgrading the telephone line network.

By December 2025 every phone line in the UK will be upgraded to the new Internet Protocol (IP) based network as Openreach switch off their analogue phone network and retire the copper based network. This means that your landline phone service won't use the traditional phone line to make calls but connect via the Internet.

This also means your phone doesn't connect to the normal phone socket but to your Broadband router.

The upgrade has already started and it's only a matter of time until your phone service is upgraded! If you already have FTTP fibre broadband, you're very likely to be upgraded very soon. Some residents in Sigingstone have already been contacted by their Communication Provider (e.g Sky, BT, PlusNet, EE, TalkTalk) letting them know they are upgrading their phone service to the new Internet Protocol (IP) based network.

What this means to you

Some benefits...

  • High Definition calling

  • Future proof

  • Communication Providers (such as Sky, BT, PlusNet, EE, TalkTalk) may offer you additional calling features that were previously charged. Such as multi-user calls and call divert.

  • Take your number on the move. Phone numbers are no longer geographically defined so you should be able to use your number from any location.

Some Important notes...

  • Compatibility of devices - Alarms, Monitoring systems, Telecare, chip & pin and Point of Sale devices, or any device that is connected to your traditional phone line will need to be upgraded in order for them to continue working.
    You will need to contact companies that supply you with such services to let them know your phone line service is moving to a Internet Protocol (IP) based network and that they will need to upgrade their equipment in order for the service to continue working.

  • When moved onto the new Internet Protocol (IP) based network, your phone won't connect to the standard phone socket but to your Broadband Router.

  • You may need to use the Broadband Router supplied by your Communication Provider (e.g Sky, BT, PlusNet, EE, TalkTalk) in to use the new phone service.

  • You may need new phones that are compatible with the service or an adaptor maybe provided - your Communication Provider will let you know.

  • Your telephone extension sockets may become redundant.

  • If you need to use the phone service during a powercut then you may need to purchase a UPS/batter backup unit. Have a look at the notes section for more info.

  • When moved onto the new Internet Protocol (IP) based network, local numbers may require you to also dial the area code in order to establish the call.

Other Notes

I've not yet received any notifications about this from my Communication Provider

Some Communication Providers are further ahead in the rollout of this service compared to others. They may also be targeting certain groups of customers first based on the current products and services they have. As an example, you're more likely to be moved onto this service first when you already have a FTTP Fibre broadband connection with the latest router supplied by your Communication Provider compared to other customers who may be using an older router or not yet on a fibre based broadband service.

If you're moving to another communication provider, you may find that they will also switch you to a digital phone service at the same time as migrating your broadband connection to them.

I have a alarm/monitoring/Telecare or other device that connects to the traditional copper phone line

If you have any device such as an alarm, monitoring devices or a Telecare system that connects to the traditional copper telephone line then you will need to contact the company that supplies you with this service to inform them that your telephone line is being upgraded to an new Internet Protocol based service.

In order for these devices to continue to work they may need to be upgraded so they are compatible or use an alternative method to communicate, for example switching to use the mobile network instead or connecting via WiFi.

  • Telecare Alarm supplied by Vale of Glamorgan Council's Adult Services
    You need to inform the Vale of Glamorgan Council's Adult Services once you know your phone service is being moved to the new Internet Protocol based service. They will provide you with new equipment that is compatible and will have a fallback to the mobile network.

Does the phone have to be plugged into the router?

It all depends on the router and phones your communication provider supplies you.

  • BT's Digital Voice:
    If you're with BT Consumer and have a BT Smart Hub 2 or there are several ways to connect a phone to BT's Digital Voice Service:
    - Connect the phone to the phone port at the back of the BT Smart Hub 2.
    - If you have the new Digital Voice handsets you can utilise the DECT functionality within the BT Smart Hub 2 to wirelessly connect the Digital Voice handset.
    - You can get a Digital Voice Adapter which wirelessly connect to the DECT functionality within the BT Smart Hub 2 and you then plug your phone into that adapter

  • Sky Talk with Internet Calls
    Unfortunately not much information is available online at present, but in one of their FAQs it does state: "Do I need a new phone? No, you can use your existing home phone with Internet Calls, but remember it needs to be plugged into your Sky Broadband Hub and not your telephone socket."

UPS/Battery backup supply units

In order to be able to use the Digital phone when there's a power-cut you will need a Batter Backup or UPS.

Communication Providers may offer you a free battery backup unit that can last an hour if you are deemed vulnerable*. Otherwise you can purchase a battery backup or UPS device online.

Here are some UPS units that can be bought to power your digital phone line service during a power outage.

Some VoIP providers include but not limited to:

Openreach - upgrading the UK to digital phone lines

Openreach need to migrate all analogue telephone lines to digital phone (Internet based) lines by 31 December 2025. That's 14 million lines and channels across the UK.

Openreach - Retiring our copper network

Openreach are rolling out their Ultrafast full fibre infrastructure to 25 million homes and businesses by December 2026. As exchange areas reach a particular coverage of this service being available then a stop sell of copper based services will be applied to that area. This means that communication providers such as Sky, BT, EE, PlusNet and Talktalk (to name a few) will only be able to offer fibre based products and services. Find out more how Openreach are retiring their copper network at https://www.openreach.com/fibre-broadband/retiring-the-copper-network

There are three main programmes that go hand in hand in trying to retire the copper infrastructure. They are:

  1. Moving to all IP and VoIP/Internet Based fixed line voice servicesThe current PSTN is becoming very costly, harder to fix and maintain. Moving to All IP and voice services moving to a VoIP/Internet based service will help reduce the cost, future proof maintainability & ease the integrations with modern systems.

  2. Moving to Full FibreMoving to All IP and VoIP/Internet based voice services is an enabler to the shift to full fibre and the withdrawal of copper products. The government wants 85% by 2026 and 100% nationwide gigabit broadband by 2030. You will find over the next 8 years that areas where Fibre to the Cabinet is available will over built with Full fibre (FTTP) along with those areas that have no fibre today and when full fibre becomes available you will be encouraged to migrate onto it before potentially a full batch managed migration onto full fibre (FTTP).There's already trial exchange areas that are currently in the process of withdrawing copper based products completely and as more areas get full fibre available to them there will be a push to move onto it.

  3. Reducing the number of exchangesBoth points 1 and 2 is therefore an enabler to reduce the number of exchanges.

  4. Below is an infographic to help explain.

I don't have a broadband connection

If you only have a landline and no broadband connection today, then when you move to a digital phone line service your communication provider will put you on a lightweight basic broadband connection based on the service type available that can just provide the digital phone line service.
