This sequence above is repeated constantly throughout the log files that 
you sent and illustrates that the problem is very likely with the Dlink 
modem being unable to demodulate the V.21 HDLC MCF message being sent by 
the receiver.

The fact that it works from the old system (I presume a different modem) 
seems to add further evidence that the problem is with the Dlink.

Actually, since you're using a software modem the issue isn't so much 
with the hardware as it is with the Linuxant driver.  This is not 
surprising.  There have been numerous reports of unreliable fax support 
with the Linuxant drivers.

Thanks,

Lee.
