could you try again with different quality settings on your hardware fax?
I see 1728 x 540 in your spandsp log.
I think spandsp is only compatible with :
standard: width=1728 x length=1128
fine: width=1728 x length=2252
super-fine: width=1728 x length=4491
which are the 3 resolution you commonly find in G3 faxes.fine: width=1728 x length=2252
super-fine: width=1728 x length=4491
I don't know what this mode is : 1728x540.
Regards,
Pirlouwi.

Marco,
First off, do not use any version over 0.0.3. I am using 0.0.3 on centos
4.5, asterisk 1.2.24 and freepbx 2.3 and it is working very well. One
very important thing to keep in mind is that faxing over voip will only
work reliably with ulaw or alaw and your internet connection MUST be
able to sustain a constant data stream with low jitter. If your
interested I have a shell script to install asterisk 1.2.24 and
freepbx-2.3 with rxfax and txfax on centos 4 and working on centos 5.

thank you for your reply.
I've installed the configuration that you suggested (asterisk 1.2.24, spandsp 0.0.3), but with no luck: I still cannot receive faxes.
Please note that I am not using T38: I am receiving faxes with app_rxfax and storing them into a dir on the machine.
I have attached an isdn trunk to the card and I am trying to receive the faxes straight from the trunk.
When receiving faxes without ecm, the sending fax machine completes with an error, and this is the log I have in asterisk:

at this point the sending fax machine hangs up and the call failes.
it seems to me that there is some kind of problem (with T.30?) in spandsp, but I do not understand what it is.
