The original CLEC recording has been copied over to the N4E machines as well, but it plays the NSN at the end of the recording. This came from 078-T (Richmond, VA)

Unable To Return Call to Pre-Paid Card Customer (October 2003)

Prior to Caller ID (actually Automatic Number Identification) being sent through the pre-paid calling platforms – when someone received a call from someone who uses an AT&T pre-paid calling card (Wal-Mart, Sam’s Club, etc.), their caller ID box shows a valid phone number ending in “9978”. If you try to return a call to this number, you get the above recording. Surprisingly, the call does “supervise” (causes a toll billing).
