BT has a range of resilient solutions, including a battery back-up unit and hybrid phone. These solutions are compliant with, and in some cases exceed, Ofcom’s requirement to provide a back-up facility for emergency calls for a minimum of 1 hour during a power outage. It is worth noting that other providers may offer different solutions.

The BT hybrid phone with a mobile SIM card inside is not a solution that will be offered to customers that have no mobile signal where they live. Instead, they will be offered a battery back-up unit which will enable them to make a phone call in the event of a power cut. These solutions are available free-of-charge to vulnerable customers - those who use a telecare device, only use landlines and or are over the age of 75, without mobile signal or broadband or have disclosed other additional needs. These will be available for all to purchase if they wish.

Many Communication Providers, including BT, engage regularly with other broadband providers, Ofcom and power companies about the resilience of their networks and have robust contingency plans in place to protect their customers in the event of planned power outages.

Landline only customers will not be required to take a paid broadband service from providers if they do not wish to. Instead, they will be provided with a dedicated internet connection and router specifically for their landline service at no extra cost.

With regard to telecare systems, lifeline alarm systems or remote ringers, I cannot state definitively which products would function over Digital Voice or which would need modification or replacement, given the range of devices and providers across these sectors. However, Digital Voice telecare devices do exist for all use cases. Furthermore, the switch to Digital Voice has already taken place in other countries; in these cases, all telecare users have been provided Digital Voice compatible devices. DSIT has been working with the Department for Health and Social Care and the telecare industry to raise awareness of the migration and to help identify alternatives, while BT and other providers have set up test labs for manufacturers to test their equipment.

BT has engaged with a broad range of external stakeholders as part of its Digital Voice migration programme. The Digital Voice Advisory Group (DVAG) has advised BT on how best to support and engage with customers who will require additional support to migrate to Digital Voice. Members of the DVAG include representative groups and charities such as Age UK, the Department of Health and Social Care, Independent Age, Rural Services Network, and Which?. BT has also invited other organisations to attend meetings on an ad hoc basis. Other Communication Providers operate similar programmes to raise awareness.

BT has engaged with local authorities in a number of areas related to Digital Voice, although no local authorities are formal members of DVAG. BT is working with local authorities via industry working groups to discuss issues such as telecare and frequently engages with the Local Government Association about Digital Voice.
