Calls not answered not forwading to Voice mail

[HUSSAINQCS]

I want to make a call to room extension if you called the room extension from operator after 6 rings if the call not answered it should reach the voicemail box of the room user.

Voice mail Type : 4645
User A (operator)-------User B(Associate set : Voicemail dir no )

I tried to manage in Phone feature cos and i made the timer no 4 to very low value but its still not going to voicemail phone keeps on ringing

Any suggestions

operators do not follow the standard forwarding applied to external callers or internal users. the operator shold have a dynamic key they press to go to voicemail.
