After answering and sending prologue signals the modem cannot hear any 
fax tones from the sender.

Okay, there is a real fax machine at the other end.  It asked us to 
repeat our prologue signals...

After repeating the prologue signals it again asks us to repeat ourselves...

And again... (it would seem that the sender can't hear us very well).

Again...

We gave up.  It would seem that the audio quality on the line was too 
poor for the audio to get through correctly in this case.

Since you're seeing 15-20% error rate it would seem to me that the 
problem is on your end.  Are you using VoIP lines?  Have you had your 
phone lines checked?  Have you tried a different type of modem?

Thanks,

Lee.
