By default, the Automated Attendant is set up with unscreened transfers, so that you must Call For-
ward the phones to the Voice Mail.
The Voice Mail software uses Trunk Mailboxes for processing inbound call information, but you
cannot program any features for them. In general, the numbering for Trunk Mailboxes starts at 01.
It is recommended that you do not change this number, unless the trunks in your phone system start
