We have Unity Conn 7.1.3.10000-68

I have a user that wants their voice mail box, after the message is left, and caller presses option to try to dial another extension, then pressess 0, that the caller is routed to a selected extension other then main operator at 0.

Example:  Caller arrives at Unity box, hears greeting and leaves message, any digit pressed after message is left, caller gets message press 1 to send message, etc.  Once they have pressed 1, they receive a message that says "if you would like to try an extension you may do so now".  If the caller pressess 0 at this point they go to the main operator at 0. 

Can the 0 option calling main operator be changed per mail box?  Or is this a global setting?  This is not the same as the "caller input".

Thanks
