The PRI signalling is more robust than any of the alternatives (except 
SS7). Call setup is faster, you can get DID, caller id and much better 
error reporting from the pstn.

I would recommend against CAS or analoge connectes whenever isdn is 
available.

Yes, this can be acclomplished in the dialplan.
