Is there any reason why you can't just install a card with two PRI ports  
(e.g. TE210P, or an inexpensive clone)  in your Asterisk box; one configured as 
NET for the old phone system to plug into, and the other configured as CPE to 
plug into the real ISDN line?

You should be able to route calls from anywhere  (LAN, ISDN30, PABX, internet)  
to anywhere else, with the right dialplan.
