Such calls that end abruptly upon reaching an answering machine often indicate a ping call tactic, where scammers probe for active numbers to target later. This is a common ploy in the UK to avoid direct engagement while confirming if the line is live. No message left raises red flags, as legitimate callers typically identify themselves. To protect yourself, avoid returning such calls—especially international ones—as they could rack up premium charges. Enable call blocking on your phone, register with the Telephone Preference Service to reduce unsolicited calls, and report suspicious activity to Action Fraud. Stay vigilant; if in doubt, hang up and verify independently.
