Chetan Khandre on Instagram: "Defensive Strategies ​You don't have to be a victim of the constant ringing. Here are the most effective ways to filter the noise: ​1. Technical Solutions ​Built-in Phone Features: Most modern smartphones (iOS and Android) have "Silence Unknown Callers" or "Call Screening" settings that automatically send unrecognized numbers to voicemail. ​Carrier Tools: Major cellular providers offer free apps (like Verizon Call Filter or AT&T ActiveArmor) that flag "Potential Spam" on your screen. ​Third-Party Apps: Apps like Hiya, Nomorobo, or Truecaller maintain massive databases of known spam numbers to block them before your phone even vibrates. ​2. Legal Protections ​National Do Not Call Registry: Register your number at donotcall.gov. While this won't stop criminals, it will stop law-abiding telemarketers, which significantly reduces the volume of calls."
