I have an HP D135 multifunction printer/scanner/fax and have been using it
for long time now to receive faxes with out much of a problem. Then I
decided to give the windows fax a chance in order to save some money that
was spend on the ink for the HP. I have discovered that it works OK with one
problem. For some reason, it will not receive faxes from certain people. If
I switch to my HP then the same faxes come in with out a problem.

Is this a know problem inherited in the windows fax program or should I try
different modem? Or is there some settings I should try?
