Calls that ring briefly before hanging up often signal a ping call, where scammers test active numbers for later targeting. In this case, the callback leading to a 'number not available' message adds suspicion, as it could mask an untraceable operation. Telecom patterns show these tactics common in South Africa-linked fraud, aiming to confirm your line without direct contact. Stay cautious: never return such calls, block the number immediately, and report to your carrier or authorities like ICASA. Enable call screening features on your phone to filter unknowns, reducing unwanted interruptions and potential risks.
