Prerequisite Features |
The CallForwardingDetection feature analyses an MT initialdp to determine if early call forwarding applies for this call. If call forwarding is pending, the call will be allowed to continue with no charging or monitoring of the call.
This feature prevents an unnecessary credit check with the OCS and unnecessary monitoring of the call when the outcome is already determined.
IF initialdp.gsm-forwardingPending is set AND initialdp.gsm-forwardingPending is true THEN instruct call to continue with no monitoring and no charging. ELSE allow the call to proceed without any affect from this feature ENDIF If the SessionType of the call is not MobileTerminating then this feature must end without affecting the call.
