Hi,

There is a progress, we were able to receive several faxes through J2
service!

Our Dialogic based faxing still fails though. This is how it goes:

Hi,

I have investigated some more fax machines that did not work with 
spandsp, and made it more tolerant. 
ftp://ftp.opencall.org/pub/spandsp/spandsp-0.0.1c.tar.gz is the result. 
 From what I have seen in today's investigations, I think this one will 
work with considerably more quirky fax machines and bad phone lines.

Regards,
Steve
