That's the system generated greeting for subscribers when they have not recorded their own. Which means you are falling through the transfer rule and to the greeting rules. Presumably you want it to ring the phone for a subscriber, right?
On a subscriber you're trying to reach go to their page in the SA and go to the "Call Transfer" page. By default transfer to the user's phone is turned off and you'll see the "No (send directly to subscriber's greeting)" radio button checked. Select "yes, ring subscriber's extension" and calls to that user via the auto attendnant will now ring their phone - of course make sure you select release to switch or supervised transfer depending on how you want to set this up - release to switch is the prefered method providing all the phones are forwarded to voice mail as they should be.
If that's not what you were trying to do, let me know...
