Yes, I have compiled and used rxfax succesfully on 1.0.9, 1.0.10 and 1.2.4 to receive from analog fax machines. I have never yet been able to get rxfax working with txfax - my debugs when I try look like the logs in your email.

Hello,
Is anyone successfully using spandsp 0.0.2pre25 with either asterisk 1.0.x or 1.2.4? I've built a Gentoo ebuild for this version of spandsp and app_rtxfax, and it builds, but I'm not having any luck getting it working. 99% of my test 
faxes fail. Reverting to 0.0.2pre20 yields a much higher success rate.
I've bumped the console debugging level in logger.conf to include debug and 
verbose, as well as the defaults.
I'm running libtiff-3.7.1, because Mr. Underwood's site recommends it, even 
though it's a vulnerable version of libtiff.
I'm faxing from a working, production asterisk 1.0.9 + spandsp 0.0.2pre20 system to a testing asterisk 1.0.10 + spandsp 0.0.2pre25 system, and 1 of 3 things 
usually happens:

1.) The fax goes through (very rare in testing)
2.) The fax loops indefinitely like this:

Of these, the 3rd one seems most common.
So, is anyone using 0.0.2pre25 in production successfully, or should I just 
stick with pre20?

Thanks!
