DNIS digits/ destination codes

[Phonedaddy]

I have a customer who has a PRI and is receiving 3 digit DNIS from the provider. The digit 8 is used for outbound access and the leading DNIS digit for the DID's is 9.

The customer needs to add some inbound numbers to the PRI, but the leading digit would be an 8 if using 3 digit DNIS. So my question is this:
Should I change to 4 or 5 digit DNIS to avoid a digit conflict with my destnation code or can I drop/insert digits in my routing tables to overcome the dial 8 or dial 9 as my primary outbound destination code?

The CO needs to give you different numbers or see if they can transpose the digits for you, the BCM can not do that.

The numbers that they will be porting over are currently setup on a RCFW to an existing DNIS. So I dont think I will be able to change the number being dialled by the caller, however if they could transpose or send other digits to simulate this then that should be ok. I'll talk with the customer and see if he can arrange for the provider to handle this. Thanks for the help Mr Cook.
