Direct VoiceMail & Group Call Question - How To Program?

[SevenOne8]

I have an old Merlin Legend System and I've been setting it up using documents I find on the internet but the only feature codes that I can't find is how to set it up to use Direct VoiceMail and Group Call. Well, we have a DVM button on all the phones but it only works on some, when I look at the master phone to see what the DVM button does it displays Direct VoiceMail and Group Call on one of them.
So I think to send a call directly to voice mail it "Group Calls" the call to extension 770.

So how can I set that button or any button to Group Call to an extension? Thanks.

Direct voice mail is used to transfer a caller directly to a subscribers mailbox, without ringing the actual phone. Think of it as a shortcut. You can also press the DVM button to access the subscribers mailbox just to leave a message.
To use this feature, just press DVM and the extension numbers of the mailbox you want to go to. You should hear 1 ring, then the greeting of the mailbox owner


The Group Call button is simply a speeed dial button to call the voice mail system in order to check your messages. Usually it is Group 770 (but it doesnt have to be)
