Phones not going to disconnect or off hook status

[double8pex]

We're testing out 3CX v8 with some Polycom 321 phones.

Issue: When we physically disconnect the Polycom's network cable and the phone shuts down, in the 3Cx Extension Status console, it is still showing the phone as connected/active with a green circle. With the phone powered down and its status shown as 'active', when we try to make a call to that extension, we get a busy signal.

- Shouldn't the call go to Voicemail? That's what the default Forwarding rule is set. We should never get a busy signal (welll, unless all the trunks are used up)
- Why is the extension status still show as active even though the phone is powered off?
- Is there a custom parameter that needs to be modified?

BTW - this same exact behavior occurs on the 3Cx soft phone when the computer loses its network connection.

Any tips or help would be appreciated. This might be a 'show stopper' on our side if we can't get this resolved.

BTW - the extension finally went to a 'Not Registered' mode in Extension Status. But that's after a 10 minute wait. Also, we did see the Registration Time out setting on the soft phone. But our main point of contention for both phones are the calls need to go to voicemail.
