It seems this week's release of spandsp fixed the major problems in the previous release, but still people have had a lot of trouble. Working with some of those who tried the software and gave me good feedback, I have identified some apparently common bugs in fax machines, and I have implemented workarounds for these in spandsp, and feedback so far seems good. I also fixed a couple of bugs. I think this version will work proper with a much wider range of fax machines. However, people have warning me that fax machines have a bad habit of not following the specs properly :-(
There is now a new tarball at ftp://ftp.opencall.org/pub/spandsp/spandsp-0.0.1b.tar.gz Please try this, and report any problems you find. This version has the following changes:
A floating point exception has been fixed
A problem with the software not properly
Some fax machines send a little less than the specified 1.5 seconds of training test data, so the training test failed every time. I now only look for 1.25seconds of training test data.
Some fax machines do not correctly initialise the scrambler in their V.29 transmit modem. I have changed the software to tolerate this.
Some fax machines send a burst of ones before the burst of zeros that forms the training test data. I have changed the software to tolerate this.
Regards, Steve
