I don't think that this could be the case here, but when visiting my
mother in a small town in Colorado last year I noticed an interesting
implementation of TT. The town is still on the old (circa 1950?)
rotary switch. Of course it can't handle TT in any way, right?

What Mountain Bell (now USWest) did was put DTMF receivers on the
input to the switch which output pulses. So I entered the tones and
could hear the pulses being generated in the background. And, no, it
was not a pushbutton phone generating pulses. It was a phone that can
so either with the switch set to tone position. I could clearly hear
the DTMF.
