When an ISDN call is received from either the AT&T network or a tandemed PRI call, Communication Manager stores the codeset 6 User Entered Code Information Element (UEC IE) when it contains the ced or cdpd. If more than one ced UEC IE is received, only the first one is stored or tandemed with the call. If more than one cdpd UEC IE is received, only the first one is stored or tandemed with the call.
