When I ran the command sh dial-plan 02037654321 it didn't match any dial peer:
Macro Exp.: 02037654321
No match, result=-1(NO_MATCH)
After I updated dial peers 1003 & 1004 from destination-pattern ^01.........$ to ^0[1-2].........$ the command then matched those peers. The output didn't mention dial-peer voice 9 though so I didn't think I had any more changes to make to the cube config. It was only when I reviewed the cube configs again I noticed dial-peer voice 9 had the line incoming called-number ^01.........$ which I changed to ^0[1-2].........$
As you've probably guessed I'm no voice engineer so completley missed the ^01 reference in Dial-Peer 9.
