You have two solutions which give trouble, and you assume the problem is 
with them, and not something else in your system. Interesting logic.

You don't indicate the kind of setup you are using. If you are trying to 
FAX over a VoIP connection, its probably that connection making FAXes 
fail. If you are using mISDN, it is probably that making FAXes fail. If 
you are using zaptel to bring in FAXes from the PSTN, spandsp should 
work well.

If you are using the agx addons to interface spandsp to asterisk, they 
have just been updated to work with the latest spandsp. This should be 
more robust in its error recovery than the older versions of spandsp. 
However, with a good connection to the PSTN you shouldn't be hitting 
recovery conditions often enough for that to be too serious.
