Since you are receiving a fax over an analog line, you can set up
MixMonitor() or Monitor() to record the fax, play it back, listen for
line noise or static or something else that may be happening that's
throwing those warnings from SpanDSP.
Obviously if you're getting a fax you're not as worried as if this
caused the fax to drop. Once you have a recording of the transmission
and the logs of what happens you can submit it to the SpanDSP project
to see what they think.
Incidentally, how verbose do you have to set your CLI to get output
that lists the warnings?
