Sure, but I can't find a cause code that means 'try next link'. do  
you know if there is one, and what this is?

Using several boxes that serve separate functions and separate blocks  
of DIDs etc, or just random numbers spread out after porting them,  
it'll be good to let asterisk do the filtering instead of relying on  
the telco.

with thousands of customers and separating callerid and sip username,  
you'll need some logic that interfaces with a dbms, and not simply  
storing it all in extensions.(conf|ael). IIRC the current realtime  
extensions support makes some three or four queries per lookup and  
isn't really easy to normalise.

but then, I might as well be wrong.

I just wondered what PRI_CAUSE to use, really.....
