Non-existent closed user group (CUG)/ Remote user initiated clearing (1TR6: AT&T ISDN Protocol)

Cause

The packet mode call is rejected because the equipment that sends the cause value does not recognize the requested Closed User Group (CUG).

Communication Manager does not support packet mode sessions on D-channels therefore, this is not applicable to Communication Manager.
