All-number calling, also known as "all-number service" or "any-number calling," refers to a telecommunication service that allows users to reach any telephone number from a single phone line or system without the need for different dialing procedures. This feature typically allows users to call local, regional, and sometimes long-distance numbers without the need for special prefixes or additional steps.
