Abstract

A method of operating a subscriber terminal to provide a flexible tapeless personalized auto-attendant telephone by means of measuring ring cadence of an incoming telephone call; and selecting one outgoing message in response to the ring cadence and playing it after a predetermined number of rings. The method also provides for the selection of group greetings and mailboxes automatically, for example, based on CLID and name match in a directory.

Claims

1. A method of operating a subscriber terminal telephone to provide a flexible tapeless personalized auto-attendant service, comprising:

(a) measuring ring cadence of an incoming telephone call;

(b) causing said telephone when in auto-attendant mode to always provide a generic outgoing message (OGM) in response to the incoming telephone call;

(c) answering the incoming telephone call after ringing said telephone for a predetermined number of rings;

(d) selecting one predetermined greeting OGM in response to a predetermined dual-tone multi-frequency (DTMF) signal and playing it;

(e) regenerating ringing in said telephone for a predetermined period in response to another predetermined DTMF signal after said playing step; and

(f) providing an OGM, for message recording, only after said predetermined period in step (e) has ended without an answer to ringing in step (e).

2. The method as defined in claim 1, further comprising the step of storing an incoming message in a memory location associated with a given OGM.

3. The method as defined in claim 1, wherein said generic OGM is repeated at least once in default of DTMF signals in steps (d) and (e).

4. The method as defined in claim 3, wherein at least one predetermined greeting OGM is an announcement-only OGM.

5. A flexible tapeless personalized auto-attendant subscriber terminal telephone comprising:

(a) means for measuring ring cadence of an incoming call;

(b) means for providing a generic outgoing message (OGM) in response to the incoming telephone call;

(c) means for answering the incoming telephone call after ringing said telephone for a predetermined number of rings;

(d) means for selecting one of a plurality of predetermined greeting OGM in response to a predetermined dual-tone multi-frequency (DTMF) signal and means for playing the greeting OGM;

(e) means for regenerating ringing in the subscriber terminal telephone for a predetermined period in response to another predetermined DTMF signal after playing the greeting OGM; and

(f) means for providing an OGM for message recording after said predetermined period has ended and regenerated ringing has not been answered.

6. The subscriber terminal telephone defined in claim 5, further comprising a plurality of memory locations for storing incoming messages associated with a plurality of outgoing messages.

7. The subscriber terminal telephone defined in claim 5, further comprising means for repeating said generic OGM in default of DTMF signals.

8. The subscriber terminal telephone defined in claim 7, further comprising means for providing an announcement-only OGM without an associated memory location for storing an incoming message.
