I live in Md. and have Verizon copper for phone and DSL. The phone I
use mostly and for these incidents is hard-wired, though fwliw the
base of that phone is also the connection for cordless phones that are
available to it, but none have been in use during this problem: Lately
there have been seemingly random interruptions in my ability to hear,
though others can always hear me.

3 times I've been in a long conversation with a friend on a cell phone
with a headset, and for substantial periods, 5 minutes or more, I
couldn't hear her. She'd had trouble with headsets before so we
thought that's what it was. But I was on the phone with a bank
yesterday, and again I couldn't hear him for 3 or 4 minutes.

I tried wiggling, pushing and pulling the plug into the handset and
banging on the handset with my hand, and it had no effect. I didn't
touch the base of the phone this time or any of these times, and
nothing strange appeared on the computer which I sometimes use while
on the phone. (The phone is a Uniden, also with cordless phones
available but not in use.)

Then all of a sudden it started working again and did so for the rest
of the phone call, 10 minutes or more, and today it worked fine for 90
minutes.

Verizon provides the phone and the DSL for the computer. Nothing for
TV. Any idea what the problem could be? ;-) Or what I should try
next?

Each phone should have a filter at their wall connection, if the line
is used also for DSL. No filter going to modem.

That's the way it is.

There are only two phones connected to the wires. This one that has
the DSL filter (and shows no static or whatever interference the DSL
would cause) and a standard Western Electric dial phone in the
basement, that is on the hook 99.9% of the time, and always when this
problem happens.

If they are already present, replace them. A few bucks each.

I'd do that, in fact I still have spares, but are you just saying this
for caution or do you really think one could be going in and out liike
this?

Thanks to both of you.

I stick a DSL filter on the old phones as well, just to keep the line
impedances in a known state, for DSL integrity where it's needed (not
for phone quality).

Early Uniden hand-sets do funny stuff, but am aware of happy campers
as well. I don't use wireless here.

Sounds internal - AGC and compression in the voice handling - either
something detecting false levels on the mic, or a failing to return to
the Rx from Tx states ~flakey mike, cord or even chip. As with most
stuff, it's not intended to be repaired.
