Hey Nate,

controller T1 0/0/0
cablelength long 0db
pri-group timeslots 1-24 nfas_d primary nfas_int 0 nfas_group 0
!
controller T1 0/1/0
cablelength long 0db
pri-group timeslots 1-24 nfas_d backup nfas_int 1 nfas_group 0
!
Can you create:

dial-peer voice 100 pots
destination-pattern 9T
port 0/0/0:D   where 0/0/0 is your Primary NFAS.


Regards,
Divin
