Response to STATUS_ENQUIRY Special intercept announcement number unassigned (NI-1: National ISDN 1)

Cause

Cause value 30 is included in a STATUS message when the STATUS message is generated because a STATUS_ENQUIRY message was received. This is a normal event and does not indicate a call-affecting problem. Communication Manager generates a call-state audit in every maintenance cycle that elicits this response from the remote end.

This cause value has local significance only. The ISDN network between the user and the equipment generating the cause value sends:

  • A no-cause indication through the network

  • A more generic cause value through the network
