Unfamiliar line
Isolated reports of an unknown number like this one highlight the prevalence of unsolicited calls in the UK. With limited data, it's tough to pinpoint the source, but such calls often stem from spam or automated systems probing for active lines. Stay vigilant: never share personal details over the phone without verification, and consider registering with the Telephone Preference Service to cut down on nuisance calls. If the ringing persists, apps like Truecaller can help identify patterns. Block the number straight away to avoid repeats, and report to Ofcom if it feels dodgy. Better safe than sorry with these mystery callers.
