Verify caller identity before engaging. This pattern of immediate hang-ups and busy callbacks often signals nuisance calls, potentially from automated systems testing active numbers. Block the number immediately to prevent further disturbances, and report it to your telecom provider or authorities like the Do Not Call registry. Enable call screening features on your phone to filter unknowns. If it persists, consider a call blocker app for added protection. Stay vigilant—such tactics can precede more aggressive spam or scams.
