[c-nsp] Can an AS5350 route ISDN calls to ISDN?

I'm trying to test this by sending calsl from a specific number from a 
specific voice port, but it's not working.

We currently have a "catch all" voip dialpeer for all other calls that 
come into this gateway that is matched whatever I try.

So, the basic setup is that I have a dialpeer that matches the incoming 
call:

dial-peer voice 20 pots
 description **** inbound from isdn, should go to isdn directly
 destination-pattern some_number
 translate-outgoing called 100
 port 3/3:D

dial-peer voice 12 pots
 trunkgroup my_trunkgroup
 description *** To Trunk ***
 translation-profile outgoing outgoing_profile
 destination-pattern 310
 forward-digits all

dial-peer voice 100 voip
 description *** catchall ***
 destination-pattern .
 voice-class codec 100
 session protocol sipv2
 session target ipv4:something

voice translation-rule 100
 rule 1 /^31\(.........\)/ /31031\1/

Incoming calls from the ISDN line all start with 31.

I want to send calls from isdn port 3/3 (currently only for a single test 
number, but that is temporary) out on the isdn lines in trunkgroup 
my_trunkgroup using dialpeer 12. I tried this by doing some digit 
manupulation, but IIRC that is done only after the outgoign dialpeer is 
matched, not during dialpeer matching.

How do I add 310 as a prefix to the calls from port 3/3 so that dialpeer 
100 does not match and calls go to dialpeer 12 (or something functionally 
similar)?

Thanks!
