You must have been well off! To even have ANY phone that early was unusual. My family never had any phone until the mid 1960's and then only because of a family emergency that required the communication.
We couldn’t get a phone until my father got hired by the highway department .Since father might be needed to plow snow or other road ergencies his boss told the phone compsny “You WILL extend the line..”
Black rotary desk phone.
Rotary phone dialing was pulse and my first pushbutton phone had to be set on pulse not tone dialing.
My early modems had to pulse dial then switch to digital operation once connected.
