I'm running a w2k3 enterprise server as an 8 port fax server using a
Multitech ISI5634UPCI/8. It receives sever hundreds of fax's a day.
However, about one in 5 fails with the following error:� Reception
error" "Unknown fatal error" "0x0000000c" MultiTech Systems
MT5634SMI-V92"

There is no source pattern to these errors and no patter to the
receiving line. I've had all of the lines tested. Disabled Compression
and I've updated the modems to the latest Windows drivers (it�s on the
Windows HCL):

Below is a single fax failure log. Any info is welcomed....
