Go to Numbers > Call Announcement
This area will allow you to edit your Call Announcement Settings Upon answer, a brief announcement will play before the call is connected. Choose to hear the default 'Incoming Call' message or record an announcement of your own. To have options of accepting the call or sending it to voice mail, turn on the accept/reject menu. Use the checkboxes to make the same changes to multiple numbers at the same time.
NOTE: Call Announcement is $2 to setup, and $2 per month, for non-bundled numbers.
