CER and Route Pattern

Unanswered Question

In the pdf for configuring CER for CCM3.3 or 4.X, in the chapter for creating the ELIN route patterns it says. "Use Calling Party's External Phone Number Mask. Select this"

Why would you select to use Calling Party's External Phone Number mask when the next step is to enter in the ELIN DID for the Calling Party transformation mask?

It's a time-saver if you have a high number of zones. For example, you can use the generic pattern ***9111 for all your zones and let CallManager / CER set the Caller ID number, rather than having to define a unique pattern for each zone.
