How to record faint sound from the Mic input?

Hi Dotan, A way I overcame the same problem was by splicing directly into
the phone. I had a 1/4 inch trs cable the had one end that was ripped off.
Of course it wasn't a cell phone as they are much harder to take apart and
much more expensive, but if it is a landline it's quite easy. Just take the
phone apart and connect the 1/4 inch cable to the + and - wire's connected
to the speaker in the phone. You should get a nice and hot signal that way.
Hope that helps,
