I'm trying to figure out how a call was made to my directors cell phone when he doesn't have message notification setup in his unity profile? The number comes through on his cell as 210-234-5555. 5555 is the pilot number for unity. I searched through CUCM 7.1 CDR and cannot find a call made during the time period the call came in, he mentioned that it happens from time to time.
Is there a way to search through Unity/CUCM to check for an extension that may have the external phone mask without having to look at 300+ phones?
