Silent or hang-up calls like this often signal automated nuisance attempts, where the caller tests active lines before pitching something. Proceed with caution—don't call back, as it could rack up charges or confirm your number's live. Block the number immediately to cut off future rings. If it persists, log details like time and date for your carrier's complaint process. Most times, these fade out, but staying vigilant prevents escalation into full scams. Keep your call screening on for peace of mind.
They called my number, and after I answered, the call was immediately disconnected.
