I think you may be misunderstanding this a bit.  Disconnect
supervision is a PSTN issue not a SIP issue.  Presumably your problem
occurs because the caller hangs up and the telco doesn't signal this
to you in a timely fashion.  Therefore your device doesn't go on hook
and it doesn't tear-down the SIP session.
