Cause
The network cannot deliver access or user information (such as low-layer compatibility or calling-name information) to the remote endpoint for any one of various reasons. For example, the call transferred from ISDN to non-ISDN facilities, or the remote end does not support delivery of such information.
This cause value is usually delivered in a STATUS message.
Communication Manager generates this cause value when:
-
A tandem call transfers from ISDN to non-ISDN trunking.
-
Calling number or calling name information or both is sent in the SETUP message when it is not needed.
-
Connected number information is sent when the network does not support it.
This cause value has end-to-end significance. Communication Manager returns this cause value to the user who has originated the call.
