Cisco phone extension will not go into voicemail when used as rollover

We have an extension set up in our Cisco Unified CM.  If you dial the extension directly, it will ring, and if not answered, it will go into voicemail.  However, the extension is also set up as a rollover number for another line.  We would like if someone calls the other line and is not answered, it would roll to this line, and if not answered, it would dump into the voicemail.  

However, although it works properly when dialed directly, if someone dials the other number, it will roll over correctly, but then rings five times, and goes to the system recording instead of voicemail.  We are running version 9.1.  

Anyone have any ideas?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Party A dials Party B and after few rings it rolls over to Party C, but you want the call to be routed to Party's B voice mailbox. I believe this is beacause Party C does not have a voice mailbox associated in Unity Connection.

Log into Unity Con. > Users > Find your Party B user  > Edit > Alternate Extension and add the extension from Party C

Now when the call is forwarded from Party C, Unity will know that it should connect with Party's B mailbox and greeting:
The issue is with the forwarded (original called line).  You need to remove the check marks from this area under the line appearance:
