Afaik it is true that it will not be included in the Asterisk source
because Steve will not disclaim the code to Digium (which he off course
is entitled to). I compiled the latest spandsp (iirc 0.0.3pre27) on a
FC6 box and it compiles fine.

On Steve's website there are versions of app_rxfax and app_txfax for
1.4. Takes some messing around with the 1.4 build system to get them
included but it worked for me last night. Those apps can be found here:

>From reading this list it seems you are better off using iaxmodem and
Hylafax (I guess that it assuming the fax comes in via TDM on the
Asterisk box). Or check out OpenPBX.org as they have done much work on
T.38 support (visit irc channel #openpbx on freenode.net to talk about
the current status).

Hope this helps.
