Feature Code - Voicemail for Extension ** Plays Generic Message

I have a law firm that wants to be able to send callers directly to a phone's voicemail greeting without transferring the call to their extension to avoid ringing the phone.  Yeastar has a Feature Code, set to ** by default, that allows you to transfer a caller directly to leaving a voicemail message for that entered extension number, but the system only plays the "Please leave your message after the tone" generic prompt instead of the custom unavailable greeting (or temporary greeting, if set) as every other phone system would normally do. 


What can be done to fix this missing functionality?
