I didn't stop, stunned, although I would be excused if I had.
He asked if I had the phone number handy. I found it on my cell phone. He jotted it down. I told him that it would likely be a service call, because we had exhausted the other possibilities in previous calls, and if so that they would want to call ahead the day they came. I said just be sure you answer the phone - the fax phone - when it rings, in that case. He planned to use that phone to call the cable company.
After he had jotted down the numbers, though, and as I was heading for the door, he did NOT pick up the phone. Instead, he went to the modem yet another time, saying something about maybe...
So I still do not know if he actually called.
