Expert Opinion
During quiet evenings in residential areas, silent calls from unknown numbers like this often signal automated systems probing for active lines. These can be precursors to more aggressive scams or just harassment tactics. No voice on the other end means hang up immediately and don't call back—block the number to prevent repeats. Report it to the FTC or your carrier for tracking patterns. Staying vigilant helps; use call screening apps to filter out junk. If it persists, consider registering with the Do Not Call list, though silent callers often ignore it.
