Unexpectedly, a wave of silent calls has been surfacing from numbers that mimic local area codes. Callers let the line ring, say nothing, then drop the call, a tactic often used to verify active lines for later spam or telemarketing pushes. Recipients should let unknown numbers go to voicemail, then block the offending ID, or employ a reputable call‑blocking app. Regularly updating your carrier's spam filter and reporting the number can curb repeat attempts. Keep an eye on any spoofed caller ID that appears out of place, and consider a secondary line for critical contacts to stay insulated from these quiet robocalls.
This number keep calling my land-line at least 2 times per month for over a year, never leaves a message, just silence
