The decision is often referred to as "any lawful device", allowing later innovations like answering machines, fax machines, and modems (which initially used the same type of manual acoustic coupler as the Carterfone) to proliferate. This ruling, commonly called "the Carterfone decision" (13 F.C.C.2d 420), created the possibility of selling devices that could connect to the phone system using a protective coupler and opened the market to customer-premises equipment. In 1968, the Federal Communications Commission extended this privilege by allowing the Carterfone and other devices to be connected electrically to the AT&T network, as long as they did not cause harm to the system. Twelve years earlier, a court had ruled in the Hush-A-Phone case that devices could mechanically connect to the telephone system (such as a rubber cup attached to a phone-company-owned telephone) without the permission of AT&T. This particular device was involved in a landmark United States regulatory decision related to telecommunications. A separate speaker was attached to the Carterfone to allow the base station operator to monitor the conversation, adjust the voice volume, and hang up their telephone when the conversation had ended. A voice-operated switch in the Carterfone automatically switched on the radio transmitter when the telephone caller was speaking when they stopped speaking, the radio returned to a receiving condition. When callers on the radio and on the telephone were both in contact with the base station operator, the handset of the operator's telephone was placed on a cradle built into the Carterfone device.

When someone on a two-way radio wished to speak to someone on phone, or " landline" (e.g., "Central dispatch, patch me through to McGarrett"), the station operator at the base would dial the telephone number.

It was electrically connected to the base station of the mobile radio system, and got its power from the base station. The device was acoustically, but not electrically, connected to the public switched telephone network.
