Hi,
After upgrading from 1.6.9 to 1.6.10 fax receive stopped; worse: it informs the other side that the fax has been received, but no file is created.
I've filed a JIRA
FS-9481 about it. I think I've located the problematic line (mentioned in that ticket).
So, if you need fax receive, don't go to 1.6.10...
