Calls from PSTN to FXO to voicemail do not disconnect

I have a tricky issue where outside calls that go to voicemail do not disconnect. I have a setup where a Comcast analog line comes in and is split. One line goes directly to an analog phone and the other goes to an FXO port on a UC520. (See attached)

When a call comes in over the PSTN to an FXO port on my UC520 and the call gets answered, or the calling party hangs up before the call gets answered, then the call terminates successfully. But if the call forwards to voicemail, then CUE answers, a voicemail is recorded, but when the calling party hangs up the call stays up. When one of the analog phones goes off hook you hear dead air then eventually a fast busy.

How can I make sure the call is disconnected after the caller hangs up?
Thanks in advance,

Re: Calls from PSTN to FXO to voicemail do not disconnect

Some more info:

When I leave a voicemail I have to do a "shutdown" on the voice-port to end the call. When I go back and check the message. I can hear my initial vm but then it is continuous dead air afterwards (until the shut ended it). It's as if CUE doesn't see the caller hanging up so it just keeps on recording.
