It's not the modem, it's the phone line quality. There is probably nothing
you can do about it.
To allow you to test his claim and get a little more evidence to support
it, or not, pick up the phone on that line, dial a 1 (or some other digit
but probably not 0) and then listen really carefully, while in a quiet room.
If you hear noise, buzzing, pops, clicks, radio stations, etc. then the
claim that it is a poor phone line is probably more believeable. If you
hear dead silence then it seems a little less so. BUT modern cheap plastic
imported phones can let you hear radio stations playing while old heavy
Bell Telephone (Western Electric) can be completely silent while on the
same phone line.
If you hear the noise and interference, even when not using a cheap phone,
you might be able to get your phone company to come out and take a look
at cleaning up the line quality AS LONG AS YOU NEVER MENTION THAT YOU ARE
USING A COMPUTER OR MODEM ON THE LINE. Tell them you hear noise when you
are trying to call. See if they will try to fix it. Often it can be as
little as a bad connection out in a box on the highway somewhere. You
mention Computer, they tell you it is your problem unless you are paying
far more "for a data quality line."
Been through all this with my mother, who lives 20 miles from nowhere.
I hope it works for you
