Thank you very much for the response. 

I would think I could have a different route table for each IF_FXO interface 
that uses a different mapping table, the devil (for me) is that the example 
config doesn't have any route table at all for IF_FXO calls, the FXO interface 
just points right at the SIP interface -- so I'm not sure how to attach the 
route.

Now that I know I'm on the right track at least I'll study the docs some more 
(and probably ping Patton) and let you and the list know what I come up with.
