Abstract

On receiving a new call, a controller in a telephone station apparatus compares the incoming caller information with caller information in stored records. On a match, an associated name is spoken over a handsfree speaker and then the controller places the telephone station apparatus in a handsfree off-hook condition. In this way, someone in a hands-busy situation or a handicapped individual may have calls from pre-selected callers automatically connected. The controller may also store a two-way or one-way communication path indication with each record and, accordingly, establish either one-way communication path from the calling party to the telephone station apparatus or a two-way communication path to and from the telephone station apparatus.

Claims

1. A method for selectively automatically answering a telephone station apparatus in a telephone network, comprising the steps of:

detecting incoming caller information from an incoming call at said telephone station apparatus;

searching a list of caller information stored in a memory of said telephone station apparatus for caller information matching said incoming caller information; and

in response to finding matching caller information, automatically placing said telephone station apparatus in an off-hook handsfree state where a voice communication path is established from a caller over at least a handsfree speaker of said telephone station apparatus.

2. The method of claim 1 including the step of, on finding matching caller information, disconnecting a handsfree microphone of said telephone station apparatus prior to placing said telephone station apparatus in said off-hook handsfree state.

3. The method of claim 1 wherein said list of caller information comprises a list of records of caller information, each record including a "two-way" voice path indication or a "one-way" voice path indication, and including the step of, on finding matching caller information in a record, retrieving said voice path indication associated with said record and, if said voice path indication is a "one-way" voice path indication, disconnecting a handsfree microphone of said telephone station apparatus prior to placing said telephone station apparatus in said off-hook state.

4. The method of claim 1 including the step of, on finding matching caller information, announcing a pre-defined announcement on the handsfree speaker of said telephone station apparatus prior to placing said telephone station apparatus in said handsfree off-hook state.

5. The method of claim 4 wherein said pre-defined announcement comprises one of a tone, beep, and ring.

6. The method of claim 1 including the step of, on finding matching caller information, announcing said matching caller information on the handsfree speaker of said telephone station apparatus prior to placing said telephone station apparatus in said handsfree off-hook state.

7. The method of claim 3 wherein said memory stores text in association with each record and including the step of, on finding matching caller information in a given record, retrieving text associated with said given record and announcing said associated text on the handsfree speaker of said telephone station apparatus prior to placing said telephone station apparatus in said handsfree off-hook state.

8. The method of claim 3 including the step of, on finding matching caller information, retrieving a voice announcement associated with said matching caller information stored in a voice memory of said telephone station apparatus and announcing said associated voice announcement on the handsfree speaker of said telephone station apparatus prior to placing said telephone station apparatus in said handsfree off-hook state.

9. A telephone station apparatus for a telephone network, comprising:

a memory for storing a list of records including caller information;

a detector for detecting caller information of an incoming call;

at least an off-hook switch and a handsfree speaker switch switch for switching said telephone station apparatus into a handsfree off-hook state;

a controller operatively associated with said memory, said detector, and at least said off-hook switch and said handsfree speaker switch for receiving incoming caller information from said detector, accessing said memory and searching said list of records for caller information matching said incoming caller information and, in response to finding matching caller information, automatically operating said at least one switch to switch said telephone station apparatus to a handsfree off-hook state.

10. The telephone station apparatus of claim 9 including a microphone switch, said controller operatively associated with said microphone switch for, on finding a record having matching caller information, opening said microphone switch.

11. The telephone station apparatus of claim 9 including a microphone switch, said controller being operatively associated with said microphone switch and wherein each record in said memory stores one of a "two-way" voice path indication and a "one-way" voice path indication, said controller for, on finding a record having matching caller information, retrieving said voice path indication associated with said record having matching caller information and, if said voice path indication is a "one-way" voice path indication, opening said microphone switch.

12. The telephone station apparatus of claim 9 including a speaker and a text-to-speech converter for announcing any text input thereto on said speaker and for indicating when an announcement is completed, said controller operatively associated with said converter for, on finding a record with matching caller information, inputting said matching caller information to said converter and awaiting an indication an announcement is completed before operating at least said off-hook switch and said handsfree speaker switch.

13. The telephone station apparatus of claim 9 including a speaker and a text-to-speech converter for announcing any text input thereto on said speaker and for indicating when an announcement is completed, said memory for storing text in association with each record, said controller for, on finding a record with matching caller information, retrieving said text associated with said record with matching caller information, said controller operatively associated with said converter for, on finding a record with matching caller information, inputting said associated text to said converter and awaiting an indication an announcement is completed before operating at least said off-hook switch and said handsfree speaker switch.

14. The telephone station apparatus of claim 9 including a speaker and a voice memory for storing voice prompts in association with records, said controller for, on finding a record having matching caller information, retrieving any voice prompt associated with said record having matching caller information and inputting said voice prompt to said speaker before operating at least said off-hook switch and said handsfree speaker switch.

15. The telephone station apparatus of claim 9 including a keypad and wherein said controller is operatively associated with said keypad, said controller for, on receipt of a pre-set indication from said keypad, storing data entered from said keypad in said list of records.

16. The telephone station apparatus of claim 9 including a speaker and a tone generator for generating a tone on said speaker, said controller operatively associated with said generator for, on finding a record with matching caller information, prompting said generator to generate a tone before operating at least said off-hook switch and said handsfree speaker switch.
