Not sure what you mean by "fxo phone", but if that really means a pstn user's
phone, then it sounds like the problem is with the spa3k detecting disconnect
supervision.

In the US, disconnect supervision is generally a momentary tip-ring open
(eg, no voltage), and the spa3k will detect that. Since you didn't mention
which country you're trying to do this in, you will need to determine what
the disconnect supervision is in use (if any) and see if there is a parameter
within the spa3k to handle it.

If you can't find anything relative to disconnect supervision for your area,
then put a voltmeter across tip-ring and see what happens when the phone
hangs up. Some countries use tones for disconnect supervision which 
obviously you won't see with a voltmeter.
