Hello, all. In addition to cellular service I still maintain a
copper-back-to-central office phone line at my residence. I've had this
for about 40 years and never had any problems - until now. Here are the
symptoms (same behavior on any one of 3 extension phones):

1. Phones ring as expected in response to calling party
2. Called party (me) can hear calling party
3. Calling party can't hear me
4. DTMF (Touchtone) phone keypads produce audio tones but won't break
dial tone.

I've got a call into Verizon on the above but am scratching my head as
to what might be causing all of this. Your thoughts would be most
appreciated. Sincerely,


Neighbor had a similar problem.
Turned out to be a busted ground wire half a mile away.
The local ground connection was enough to make the audio
work, but the broken wire made the other stuff fail.
