UCCX ANI Lookup

Hello all,

I’m looking to write a CCX script that can route calls based on the calling number. E.g. If Calling number 3034117911 call to the CCX trigger the script check the Calling number and route that call to a certain Resource Group or Agent every time, if the agent is not available queue it in the default queue. I know how to do this on inidivual based Calling Numbers but the problem i am having is that i have a pool of 160,000 + numbers. What would be the easiest way to accomplish this?
