Silence d'appel
Silent calls like this one from an unrecognized number often signal automated systems testing active lines or potential spam setups. In the telecom world, these dead-air hangups frustrate users and can precede more aggressive tactics. Hang up immediately if you pick up—don't engage or press buttons, as that confirms your number is live. Register with the national Do Not Call list to cut down on such nuisances, and consider apps that screen unknowns. If it persists, report to your carrier or authorities; blocking the number helps short-term, but scammers rotate lines anyway.
