[Asterisk-Users] VoiceMail + Forwarding + Directory Dial by Name : How?

[Frank]

Searched the wiki and googled extensively to no avail.

How can the Directory App be used by a VoiceMailMain user to forward a
voice mail to another voicemail user and do it by a directory 'dial by
name' lookup?

Ex.  A voicemail system with 1000+ subscribers.  One user wants to
forward another user but has not idea what their extension or voicemail
box number is.
