The ability to restrict incoming calls on a landline telephone is a feature designed to prevent unwanted communications. This encompasses blocking calls from specific numbers, anonymous callers, or entire area codes. For instance, a user might utilize call blocking to avoid repeated calls from a telemarketing company or an individual engaging in harassment.
Controlling incoming calls offers a more peaceful and secure home environment. Historically, call blocking required specialized equipment or complex intervention from the telephone service provider. Modern methods, however, often involve simple keypad entries or online account management, empowering users with greater control over their communication experience. The benefit is reduced disruption and enhanced privacy.
