Abstract

A digital telephone answering device (DTAD) that allows messages to be forwarded to certain internal mailboxes. Random access memory (RAM) is flexibly and dynamically controlled by a microprocessor or controller. Audio signals in the form of voice messages are digitized and stored in the RAM. Messages can be sorted and allocated to specific mailboxes and made retrievable by pressing a button assigned to that mailbox. Messages can also be moved or re-assigned from a common message area to a certain mailbox or mailboxes. Outgoing messages are also stored in RAM and can be of sufficient number to have an outgoing message correspond to each incoming message storage area. The normal message recording and message playback functions of the DTAD may be activated after the call has been answered on the receiving side. Memos can be appended to messages that have been moved or re-assigned from a common message area to a certain mailbox or mailboxes.
