I assume if you are using spandsp-0.0.4pre6 you have adapted 
app_rxfax.c. and app_txfax.c to work with it.

I haven't heard from anyone using tobit or shamrock software (who on 
earth wants to call their company tobit? weird). I have no idea what fax 
header crossbars might be. Do they have some kind of bicycle integration 
in their product? :-\

Is your problem when sending from Asterisk or receiving? Can you enable 
debug and e-mail me a log and (assuming its a receive problem) the 
resulting TIFF file.
