We've done the same but with 2 BT PRI's in and out (using a TE405P).  As 
others have said, they need to be EuroISDN, but CLI, DDI etc all pass 
through to our old Avaya INDeX without having to modify the INDeX at all, 
all calls in and out work fine.  Configure one span as PRI_CPE and one as 
PRI_NET.  Should * play up, just move the cables from the * and plug back 
into the switch.  We're trying to look at ISDNguard from Junghanns to do 
this for us without the need to be on site and move the cables physically.
