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.
