Built-in Call Blocking Features

Many modern landline phones come with built-in call blocking features that allow users to block specific numbers or categories of callers. 

These features may vary depending on the phone model, but common options include:

  • · Anonymous Call Rejection: With this feature, you can block calls from numbers that have their Caller ID information withheld. This helps to prevent unwanted calls from telemarketers and scammers who often hide their numbers.

  • · Do Not Disturb: This option allows you to set specific hours during which your landline phone will not ring, helping you maintain your privacy and prevent disturbances during your preferred quiet times.
