    I am having a problem with a External Trunk Configuration / Address Transformation ? using regex expressions. We are trying to restrict the outgoing CLI(ANI) for Queue Initiated calls to the DID number range that has been allocated to the Customer ORG. This is being done as the Customer has the ability to number spoof by allocating any Number for the specific queue. (Carrier allows this).  Unfortunately the regex expressions we are using don't seem to work. What are we missing here.

    Can you provide more details on what is not working?  Also, if you are trying to set the ANI of queue initiated calls, have you tried to use the "Calling Party" parameters on the queue?  [ Set behavior and thresholds for all interaction types ] \ [ Voice Channel ]

    A couple more questions that might help in debugging:
    1. Are you doing any number transformation on the Number Plan in use? (Telephony->Sites->Number Plans)
    2. And just to clarify - are you wanting to deny the call from connecting or are you wanting to enforce a default if the ANI does not fall in the range?

    Stavros, just to make sure we all understand...

    Basically, you support a Customer and only provide a small range of phone numbers they are allowed to use as the ANI for outbound calls.

    They are taking advantage of the ability to type in any phone number they want in the Voice tab on the queue configuration, even though the nukmbers are not in the allowed range (they are spoofing numbers that do not belong to them).

    You tried to use the Trunk configuration to change the numbers back to the correct range, but it did not work using the regular expression option in Identity.

    Question - do you need other users and entities to be able to supply their DIDs as the ANI on outbound calls? Or, can you restrict everything to just one phone number as the ANI for the organization?
