I forgot to mention that I didn't yet get fax tone detection working, my
success so far has been setting up an extension for spandsp which I am
calling from my fax machine on another extension.  The fax machine is
hooked up to a fxs port on my TDM22B.  I haven't tried it yet, but I
believe that the fix is in adding one of the following to zapata.conf:

;faxdetect=both
;faxdetect=incoming
;faxdetect=outgoing
;faxdetect=no

I also think the following are needed:

echocancel=yes
echocancelwhenbridged=yes
