Cisco IP Phones Still Connected After FXO Go On-Hook

My problem not on the FXO, my problem on the CUCM and IP Phones, that the phone still connected after the FXO return to On-Hook for 30 Seconds.

for example if i shutdown the FXO will it in active call the IP Phone will still in the connected state for 30 seconds, and the user hear a tone at this period.
