Direct to VoiceMail (almost)

record greeting message to say:welcome to bla bla bla.
"for a company directory please enter 77 now or please hold and your call will be answered automatically"

record aux.ogm to say:
to leave a vm for bill enter 301
to leave a vm for john enter 302
to leave a vm for mary enter 303
etc....

the caller enters 77,the aux ogm message plays and the caller gets the company directory.
then enters the extention number...voice mail goes directly to the extention they dialed.
when the caller enters an extention number,the system says "please hold while i direct your call to that extention"

if the caller enters no extention number then the aa answers the call and leaves the vm on extention 301.

if the caller enters 77 then they can either enter an extention number or wait for auto answer.
auto answer will put the message on 301.
