Register with the national Do Not Call registry

If you live in the US, register your phone number with the official Do Not Call registry. Go to [donotcall.gov](https://www.donotcall.gov/) or call their toll-free number to register. This list makes it illegal for legitimate telemarketers to call your number. While scammers will ignore this list, it helps you identify unauthorized calls immediately. It filters out compliance-abiding corporations from the network lines. It is highly recommended to perform these maintenance checks at least once a month to ensure optimal device performance. In addition, keeping your device software updated will prevent compatibility problems and protect your personal files from potential security vulnerabilities. Verify each option in detail to prevent configuration conflicts with your hardware profile. Doing this regularly keeps your system stable, fast, and secure for everyday use.

PRO TIP:It takes up to 31 days for your registered phone number to show up on the active registry lists.

It is highly recommended to perform these maintenance checks at least once a month to ensure optimal device performance. In addition, keeping your device software updated will prevent compatibility problems and protect your personal files from potential security vulnerabilities. Verify each option in detail to prevent configuration conflicts with your hardware profile. Doing this regularly keeps your system stable, fast, and secure for everyday use.

Avoid speaking or pressing buttons on robocalls

If you answer a call and hear a robocall recording, hang up immediately. Never speak, press numbers, or ask to speak to an agent. Interacting with the system confirms your line is active, which will lead to more scam calls in the future. It updates their auto-dialer database flags, causing your number to be shared with other scam groups. It is highly recommended to perform these maintenance checks at least once a month to ensure optimal device performance. In addition, keeping your device software updated will prevent compatibility problems and protect your personal files from potential security vulnerabilities. Verify each option in detail to prevent configuration conflicts with your hardware profile. Doing this regularly keeps your system stable, fast, and secure for everyday use.

Robocall Response Strategy: - Do NOT say 'Yes' (scammers record this to authorize charges) - Do NOT press buttons to opt out - Hang up immediately - Block number in recent call history
