# Tree Mailboxes and NP Forms

Tree mailboxes allow callers to press DTMF keys to choose from several options, and can be used either before or after an NP Forms application.

When a Tree mailbox precedes an NP Forms Rotational mailbox, callers can select alternatives to filling out the NP Form, such as transferring to a live attendant or leaving a message in another mailbox. By setting the Rotational mailbox as the first mailbox in distribution list 01 and including feature bit 120 (Default to First Child of Tree Mailbox) in the Tree mailbox FCOS, callers with rotary dial phones are automatically transferred to the NP Form where they are prompted with the first question.

If the last mailbox in distribution list 01 of the Template mailbox is a Tree mailbox, callers can select additional options after completing an NP Form. (The Template mailbox must contains FCOS bit 139.) The Template mailbox plays the greeting of the Tree mailbox, then allows callers to select from the choices listed in the greeting. This way callers can return to a "higher menu" or hold/transfer for live assistance. Again, if the FCOS for the Tree mailbox contains bit 120, callers with rotary phones can be automatically transferred to a specific extension or mailbox.
