This document will provide instructions on how to collect debugging logs from an Asterisk machine for the purpose of helping bug marshals troubleshoot an issue:

In short, Digium provides support for these fax standards which are still under patent and includes licensing for those standards. Spandsp does not.

Hmm, it looks like we completely ignore the modems setting in res_fax_spandsp. I am looking into it.

Kristijan - I've gone ahead and committed this, as the fix is fairly straightforward and it passed the internal tests. If you have a problem with the patch, please feel free to have this issue reopened.
