Autopatch

Phone Patch in Vietnam War, 1969

An autopatch, sometimes called a phone patch, is a feature of an amateur radio (or other type of two-way radio) repeater or base station to access an outgoing telephone connection.[1] Users with a transceiver capable of producing touch tones (DTMF signals) can make a telephone call, typically limited by settings in the autopatch module to be only to flat-rate numbers, such as local calls or toll-free numbers.
