How to setup Voicemail only telephone line? Mitel 3300

Currently I have a line where calls go to a phone line rings and eventually sends them to VM where a message is played and they
can leave a message. So I'm just trying to get the line to directly go to VM as this phone will not be answered, bonus points if we can do this without using
an IP license.

Although there are tons of ways to do this, the most common way I do this is with an ACD Express Path.

Create an ACD Express Path Group with a DN that matches the mailbox and set the Unavailable Answer Point Directory Number to the VM Hunt Group DN. Now point your DID to the ACD Express Path and you are done. No licenses needed.

Trusted device (doesn't burn a license) set with an always re-route to voicemail, then create a voice mailbox that matches the trusted device DN.
