Dave,

I was interested in this for a client, some time ago.  With Asterisk's lack
of hardware supporting analogue DID circuits, I found it to be more cost
effective to convert the analogue DID trunks to a PRI-based service.  You
get much more flexibility, and call setup is WAY faster.  Also, should you
decide you need more trunk capacity, it is just a service order -- no truck
roll.  

If you do find a solution supporting the analogue trunks, please be sure to
share it with me.
