Becasue of all the issues with fax over voip, we want to use pstn for
our fax machine, but not dedicate a line just to fax.

I'm thinking of having asterisk answer the pstn line, check for fax
tones, and route appropriately. In zapata ( chan_dahdi ) set
faxdetect=incoming

then the dial plan would have

[incoming-pstn]
exten => fax,1,Dial(DAHDI/1)  ; the fax machine
exten => fax,2,Hangup()

exten => s,1,Answer()
exten => s,2,Dial(DAHDI/2)   ; internal extension
.............

Would this work? I'll need another TDM410 card to do this, so I'd like
some reassurance before I go purchase it.
