This is a common problem. You have to answer a few questions if you want
to fix it:

Does your telephone company provide any kind of analog disconnect
supervision? This is sometimes called "Calling Party Control".

Some companies will configure this if you ask them.

If the answer is no, you will have to use tricks to make Asterisk
consistently detect disconnection. The tricks don't work well.

Where are you located?
