This may be a silly question but, are you sure there is no noise on the phone 
lines?

Are you on direct exchange lines or going via a PABX?

Have you done a "loopback" test, dialling out on one line and coming back in 
on another?  (Easy with voice .....  for data, you will need to set up mgetty 
instead of faxgetty, and run minicom or a similar terminal emulator.)
