Changing the last digits of your phone number

[DanielEsteve]

What do you call the process/system which enables outward bound companies to randomly change the digits at the end of their phone number?

Thanks,

Daniel

Are you talking modifying the External Phone Number Mask on a phone which then , assuming you control ANI, the telco will outpulse?
