Call barring is a telecommunications feature that enables users to restrict certain types of outgoing or incoming phone calls. It is a security measure that allows individuals to control and manage their phone usage, preventing unwanted or unauthorized calls from being made or received. Essentially, call barring serves as a protective barrier that limits communication with specific numbers or categories of phone numbers.
By activating call barring, users can designate specific restrictions, such as blocking all incoming or outgoing calls, barring international calls, or preventing calls to specific numbers or groups. This feature is particularly useful in situations where users wish to prevent unexpected high bills resulting from international or premium-rate calls, avoid harassment from certain individuals, or restrict phone access for children.
To activate call barring, users typically need to contact their network provider and request to enable this service. In some cases, depending on the phone and network, individuals can access call barring settings directly through their device's settings menu. When call barring is active, users are required to enter a password or PIN code to modify or disable the settings.
It is important to note that call barring is a network-dependent service, and its availability and functionalities may vary depending on the user's service provider and plan.
The term "call barring" originates from the combination of two separate words:
1. "Call": In this context, it refers to a telephone call or communication made using a telephone network. The word "call" itself traces back to Middle English and Old Norse, ultimately derived from the Proto-Germanic word "kallon", meaning "to shout" or "to summon".
2. "Barring": It is derived from the verb "bar", which is also used in legal contexts to mean "exclude" or "prohibit". The word "bar" comes from Middle English, via Old French "barre" and Latin "barra", ultimately believed to be of Celtic origin.
So, when combined together, "call barring" essentially means the act of excluding or prohibiting certain phone calls or communications.
