hi folks.
i recently upgraded asterisk to 1.6.1.17(from 1.2) and i'm having
problems with fax. after receiving fax with the ReceiveFAX app.
everything seems ok. the .tiff file was there, phone line seems
to hang up. then asterisk will crash. any ideas?
also i looked in the log file. this is what before it crashed:

Many machines will happily build and install a library to /usr/local, and then successfully like applications against it, even though /usr/local is not in the library search path. Dumb, but true. The installation information page for spandsp, at http://www.soft-switch.org/installing-spandsp.html , warns about these issues. Steve
