You are running into and fxo disconnect-supervision issue

To understand the problem and fixes, please see:

note 1: unless you are in north america, ground-start and some other things does not apply:

note 2: to get around the problem definitely, used ISDN BRI.

hope this helps, please rate post if it does!

What happens in 99% of the cases, is that you have to configure the exact disconnect tones as described it the document. No other method works.
