[Freeswitch-users] FAX problems

I'm still struggling with sending FAXes from a Windows 7 system.  I believe
my requirements are simple: The ability to send a document (like a Word
document or a QuickBooks invoice) directly from the Windows system to a FAX
number.  I don't want to have to use a physical modem and an ATA device.  I
don't want to run Windows in "Test" mode in order to use an unsigned
driver.  I don't mind paying some money for a commercial software product.

The setup is simple:  I have FreeSwitch installed on a Linux machine, on
our LAN.  Also on the LAN I have several Windows 7 machines and an ATA
device (an OBi100).  An analog FAX machine is plugged into the ATA.

What works:
I can send a fax from the FreeSwitch machine using txfax.
I can send a fax through the ATA and the FreeSwitch machine using the
analog FAX machine.

What doesn't:
I tried www.t38faxvoip.com through FreeSwitch.  It doesn't work.
I tried www.t38faxvoip.com directly to Flowroute.  That didn't work either.
I called the analog fax machine through the ATA and FreeSwitch from
www.t38faxvoip.com.
I tried www.faxback.com.  Same results.

The people at www.t38faxvoip.com at least responded to my emails, but said
they didn't know what was happening after looking at my Wireshark dump.

All of the tests from Windows behaved the same.  The called FAX machine
answered, but never completed the handshake.  The software reported that
the call was answered by something other than a FAX machine.

Yes, we can live with printing out the document and sticking it in the FAX
machine, but it sure would be nice to be able to save some paper.  Can't
anyone solve my problem?
