You mentioned that you had trouble with 5.0.3.  ?

It's behaving exactly as if you've disabled ECM... either by request in 
the fax job or somewhere in the configuration.

Yesterday we were discussing Class 2 and now Class 1 ... it's more 
likely, now, that the issue is with the job submission itself.

Even when using Class 1.0 the effect of disabling ECM will be that the 
maximum transmission speed that you'll see is 14400 bps.

When you finish this make sure that libfaxserver.so and libfaxutil.so 
(symlinks) point to the correct DSO files.  I would even suggest 
deleting the others.

And you're not using the -E option, so that seems to further indicate 
that there is some problem underneath the surface... but still 
apparently on the client-side.

Examine the sendq file before the job completes.  See if, indeed, ECM is 
disabled... look for "desiredec".  It should be "1" for enabled and "0" 
for disabled.
