If they have a # to call into which is something like call-forward-all, obviously UC won't be able to have knowledge of every single external number and be able to dump them into a specific user mailbox, so as long as you at least reach the default opening greeting, or maybe a configured call handler (info in the call management link I sent you), they can enter their extension, then their password and it'll drop them into their voice mail.
An easy way that I can think of is to create a CTI route point that accepts all external calls or dummy device that is set for CFA to voice mail. Then create a routing rule to match the extension of the dummy device and act accordingly by sending it to a call handler which sends everyone directly to sign-in.
