It wasn’t or rather didn’t have a phone function. It’s pretty funny that most code input arrays back in the day mimicked phone keypads aesthetically (ivory white buttons with the number and alphabet and symbol nomenclatures). Even the silly largish size of the Clifford keypad is unnecessary - it coulda been half the size and consequently less obtrusive. But alas it was the era of largess that Clifford ruled the car alarm world. To this day I still have some wires from the system in my car (the 9v replaceable battery backup port lol)
