[Asterisk-Users] fax with asterisk

[Justin Richards]

I'm not using any Digium cards.  I'm actually using SpanDSP and
app_rxfax to process incoming faxes.

After drilling into it for about 8 hours yesterday I come to realize
that there is a lot more to it than the asterisk upgrade.

I patched my FC3 box, which means libtiff is now 3.6.1 which according
to Steven (spandsp) is broken for this application.  First, i compiled
the latest spandsp which didn't make a difference. I re-compiled the
rxfax and txfax apps, got nowhere.  Finally started trying to revert
to an older libtiff, but apparently went too far back (3.5.7) and
ended up getting core dumps.  I am need to downgrade libtiff to 3.6.0,
and everything dependant on libtiff to try again.  simply downgrading
libtiff on its own doesn't work well.. :-(

Thats what I get for patching.. :-)  This setup worked nearly flawless
until I upgraded, so I'm pretty sure I can get it back again after i
downgrade the right stuff in the right order.  If anyone has that
list, please share!!
