If you are using PRI then you can use the OLI feature under Terminals and sets to put whatever name you want to show in outgoing caller ID.
If not then you are going to call Telco and ask them to change your customer's BTN (beginning telephone number) to one of the other numbers. They should be able to do that relatively easily.
