[Asterisk-Users] txfax failure

Hi list,

Just installed spandsp. In my limiting testing, I have an issue on a 
Philips fax machine (HFC21) directly connected to my * server through 
TDM400, reception with rxfax works fine, but txfax always fails. Below 
is a transcript of failed transmit.
This is with asterisk-1.0.3 (with native moh patch but I don't think it 
is the source of the problem). I already tried libtiff 3.5.7, 3.6.0, 
3.6.1 (with hylafax patch), with same results. Echo cancel is off on the 
zap channel, though I don"t think this is still needed. I have read the 
wiki, scott's faxing with asterisk, the mailing list, found nothing on 
bug tracker.
On a test to a Sagem fax (through the PSTN via TDM400 on my side) txfax 
worked flawlessly, so this is obviously related to the Philips fax, but 
maybe there is something in the logs below that shows the source of the 
problem, and a help fix it. I'm available for more testing.

Thanks,
Jean-Denis Girard
