The UK’s telecoms networks are undergoing significant upgrades as companies transition landline customers from the traditional PSTN to VoIP, offering benefits like clearer calls. While most customers will find the transition straightforward, some may require additional support, particularly those reliant on security alarms or with only a landline. Various organisations, including Ofcom, are ensuring minimal disruption and consumer protection during this change. Ofcom’s rules mandate equivalent protections for phone users regardless of their landline delivery method, prompting a review of telecom regulation to meet evolving needs. Our document explains the changes, stakeholders' roles, and expectations for providers, aiming for clarity on Ofcom's role and related work. Ofcom’s strategy focuses on fibre broadband investment and competition while safeguarding consumers. Transitioning to broadband calls is crucial for the successful shift from the copper network, with expectations also relevant for early fibre adopters.
