This is where the receiving modem is supposed to have sent CFR.  We 
don't know for sure if it sent it because the sending modem didn't get 
it, but we can assume that it did because it appears that you are using 
this for receiving other faxes.

I'm probably the only one here who will find this amusing, but this is 
funny that the receiving modem thought that the sender's retraining was 
Phase C image data consisting of 15 lines and wants to confirm it as a 
page receipt.  :-)

This is why Class 1 is so much better to use.  ;-)

Okay, so here's what the problem likely is.  This is from your send-side 
log that you sent before:

It's obvious now what is the problem.  That AT+FRS=1 is bad form.  It 
shouldn't be there.  It's causing the sender to miss the receiver's CFR 
signal.  Please remove Class1ResponseWaitCmd from your modem config file.

Thanks,

Lee.
