Ofcom is today consulting on a technical clarification to its ‘calling line identification’ guidelines.
These guidelines are designed to help phone companies comply with Ofcom’s requirements that information carried with a call – and the numbers displayed to people receiving them – must be valid, dialable and uniquely identify the caller.
This information can help people to screen incoming calls from numbers they don’t recognise. It can also help regulators to trace those responsible for making nuisance calls.
Purple customers located in any UK geographic region can be provided with CLI numbers that meet these requirements, for their business needs.
