## Abstract

A method and apparatus for providing voice messaging services from a plurality of central office facilities is disclosed. Customer voice messaging computers are provided access to the central office facilities via an adjunct SMDI processor. The processor preferably includes an appropriately programmed AT-compatible computer and board.

## Claims

### Claim 1

A method of providing voice messaging service to a single user comprising the steps of:
a) providing a central voice messaging system having a central message processor;
b) providing a plurality of simplified message desk interface ("SMDI") voice messaging computers having connections to said central processor, each of said voice messaging computers having a plurality of mailboxes;
c) providing a plurality of central office facilities having connections to said central message processor, each of said central office facilities being coupled to a plurality of telephone lines and associated with said SMDI voice messaging computers;
d) providing a single link between said single user and said central voice messaging system; and
e) providing at least one voice messaging service to said single user from each of said voice messaging computers indirectly through said single link to said voice messaging system.

### Claim 2 (depends on 1)

The method as recited in claim 1 further comprising the step of answering a plurality of telephone lines in one of said mailboxes.

### Claim 3 (depends on 1)

The method as recited in claim 1 further comprising the step of activating a stuttered dial tone on said plurality of telephone lines in said plurality of central office facilities.

### Claim 4 (depends on 1)

The method as recited in claim 1 further comprising the step of activating a first of said mailboxes in response to a first reason for entry, a second of said mailboxes in response to a second reason for entry, and a third of said mailboxes in response to a third reason for entry.

### Claim 5 (depends on 1)

The method as recited in claim 1 further comprising the step of providing an appropriately programmed digital computer in said central message processor within said voice messaging system.

### Claim 6 (depends on 5)

The method as recited in claim 5 further comprising the steps of interconnecting said SMDI voice messaging computers to said digital computer with SMDI data links; and indicating a failure in said data links with an alarm.

### Claim 7 (depends on 6)

The method as recited in claim 6 further comprising the step of activating said alarm after a predetermined number of pulses from a clock occurs in the absence of a periodic signal.
