Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, whether her Department has made an assessment of the potential impact of digital voice services, compared to the legacy Public Switched Telephone Network, on protection against scam and spoofed calls.

The Government is committed to ensuring that any risks from the industry-led migration of the analogue Public Switched Telephone Network (PSTN) to digital Voice over Internet Protocol (VoIP) are mitigated for everyone across the UK. Ofcom have confirmed that VoIP technology is more resilient, more secure, enables better quality phone calls, and can be used to block scam and spoofed calls. For example, BT Digital Voice blocks over 17,000 scam calls every day.
