The word "dialed back" originates from the field of telecommunications, specifically from the use of rotary dial telephones. In the early days of telephony, rotary dial phones were used to make calls. To dial a number, users had to rotate a dial with numbered holes corresponding to the digits, and each number would produce a certain sequence of electrical pulses.
The term "dialed" comes from the action of rotating the dial to select a number. This action would send the appropriate electrical signals down the line to a central office, which would route the call to the desired destination.
The phrase "dialed back" specifically refers to the action of rotating the dial in reverse or counter-clockwise to cancel a previously dialed number. This was necessary if a mistake was made while dialing a number, or if the user wanted to cancel an ongoing call.
