To route based on calling number on the GW/CUBE you can use "answer-address" in the dial peer:

Or if have somewhat newer IOS you can use URI machining:

In addition to what Chris said [+5], please check the following if you want the same in CUCM. Although the title is 'Blocking calls based on calling party' but you can apply the same rule to route the calls to any destination on the basis of calling number.
