Abstract

A method for receiving and delivering voice messages responds to the inability of a caller to complete a call from a calling station to a called station to automatically cause the calling station to default to a voice message center. If the caller desires to leave a voice message to be delivered to the called station, the caller is prompted to store the voice message. Thereafter, the voice message center initiates an outdial routine which makes a predetermined number of attempts to deliver the voice message to the called station at predetermined time intervals. In the preferred embodiment, the method is incorporated in a multiple user station telephone system in either a "shared tenant services" or "on-campus" configuration.

Claims

1. A method for receiving and delivering voice messages over a telephone system having a voice message facility connectible to one or more calling stations and a called station via a central office, comprising the steps of:

(a) receiving and storing a called number at a calling station, the called number identifying the called station;

(b) transmitting the called number from the calling station to the central office via a trunk to initiate a call to the called station;

(c) evaluating whether the called station remains on-hook for a predetermined number of rings or is busy;

(d) if the called station remains on-hook for a predetermined number of rings or is busy, disabling a handset of the calling station and disconnecting the call from the trunk to prevent access to the voice message facility via the handset;

(e) speed-dialing the voice message facility from the calling station while the handset is disabled;

(f) reactivating the handset when the voice message facility goes off-hook and then automatically inquiring whether the caller at the calling station desires to record a voice message for the called station;

(g) if the caller desires to record a voice message for the called station, recording the voice message and the called number at the voice message facility;

(h) evaluating whether a predetermined number of attempts to deliver the recorded voice message to the called station have been made;

(i) if a predetermined number of attempts to deliver the recorded voice message have not been made, transmitting the called number from the voice message facility to the central office to initiate a call to the called station;

(j) evaluating whether the called station remains on-hook for a predetermined number of rings or is busy;

(k) if the called station goes off-hook within the predetermined number of rings, automatically transmitting the recorded voice message from the voice message facility to the called station; and

(l) if the called station remains on-hook for a predetermined number of rings or is busy, repeating steps (j)-(l) until the predetermined number of attempts to deliver the recorded voice message have been made.

2. The method for receiving and delivering voice messages as described in claim 1 wherein the step of recording the voice message and the called number includes the step of:

storing the voice message and the called number in a call queue of the voice message facility, the call queue having a plurality of addressable storage locations.

3. The method for receiving and delivering voice messages as described in claim 2 wherein step (i) includes the steps of:

retrieving the recorded voice message from the call queue;

determining whether the voice message facility has an available access port from which the recorded voice message can be delivered to the called station;

if the voice message facility does not have an available access port from which the recorded voice message can be delivered to the called station, storing the recorded voice message in a subqueue of the voice message facility at a predetermined position;

retrieving the recorded voice message from the subqueue when the voice message facility has an available access port from which the recorded voice message can be delivered to the called station; and

transmitting from the available access port the called number associated with the recorded voice message prior to retrieving another recorded voice message from the call queue.

4. A method for receiving and forwarding voice messages over a telephone system having a voice message facility connectible to one or more calling stations and a called station via a central office, comprising the steps of:

receiving and storing a called number identifying the called station;

transmitting the called number from the calling station to the central office via a trunk to initiate a call to the called station;

evaluating whether the called station remains on-hook for a predetermined number of rings or is busy;

if the called station remains on-hook for a predetermined time or is busy, disabling the handset of the calling station and is connecting the call from the trunk to prevent unauthorized access to the voice message facility via the handset;

speed-dialing the voice message facility while the handset is disabled;

reactivating the handset when the voice message facility goes off-hook and then automatically inquiring whether the caller at the calling station desires to record a voice message for the called station; and

if the caller desires to record a voice message for the called station, connecting the calling station to the voice message facility and transmitting the called number thereto.
