Bug#469451: asterisk-app-fax: app_rxfax does not receive fax

[root]

Package: asterisk-app-fax
Version: 0.0.20070624-1
Severity: important

After upgrading from previous versions of app_rxfax and libspandsp
my asterisk box stopped to receive faxes with rxfax application.
Can it be some kind of regression?

Here is some full log cut:
