Abstract

A method for facilitating call completions utilizing a call identification telephone number which is transmitted along with an incoming call. A user of the call processor of the invention can program a list of anticipated or preferred call identification telephone numbers, together with destinations to which it is desired to route the respective incoming calls. During an incoming call, the call processor matches the associated call identification telephone number with a preprogrammed number and thereby completes the call according to the programmed destination.

Claims

1. A method for controlling routing of a telephone call, comprising the steps of:

programming a route directory with at least one potential calling party identity to be associated with one of a plurality of destinations including an intended called party and a voice messaging facility;

receiving an incoming telephone call directed to a switching system and receiving an identity of a calling party placing the incoming call;

accessing the route directory in response to the incoming call to determine the destination route of the incoming call based upon the identity of the calling party; and

connecting the incoming call to the destination specified in the route directory.

2. The method of claim 1, further including providing a route directory for a plurality of telephone users of the switching system.

3. The method of claim 2, further including allowing each said telephone user with a capability of modifying the route directory to reroute incoming telephone calls to different destinations.

4. The method of claim 1, further including accessing the route directory using a telephone number as the identity of the calling party, and executing a routine to connect the incoming call to a destination cross-referenced to the telephone number.

5. The method of claim 1, further including arranging a message having a call identification number content, and transmitting the arranged message to the voice messaging facility.

6. The method of claim 5 further including causing the voice messaging facility to record the arranged message prior to a recording of a message deposited by the calling party.

7. The method of claim 1, further including connecting the incoming call to an alternate destination comprising a person other than a called party who has a destination defined in the route directory.

8. A call processor for carrying out the steps of claim 1.

9. A method for controlling routing of a telephone call, comprising the steps of:

receiving an incoming telephone call directed to a switching system and receiving calling party location identifying information of a calling party placing the incoming call;

storing the identity of the calling party in a route directory of a call processor in association with one of a plurality of destinations;

accessing the route directory in response to the incoming call to determine the destination route of the incoming call based upon the location of the calling party;

connecting the incoming call to the destination specified in the route directory; and

transmitting to a called party a prerecorded voice message identifying the geographical area defining the area of origination of the incoming call.

10. The method of claim 9, further including transmitting to the called party a voice message identifying the geographical area as a numerical area code.

11. A method for controlling routing of a telephone call, comprising the steps of:

receiving an incoming telephone call directed to a switching system and receiving an identity of a calling party placing the incoming call;

storing the identity of the calling party in a route directory of a call processor in association with one of a plurality of destinations;

accessing the route directory in response to the incoming call to determine the destination route of the incoming call based upon the identity of the calling party;

connecting the incoming call to the destination specified in the route directory; and

programming said call processor with an area code look-up table for cross-referencing a voice message which is transmitted to the called party concerning the geographical area of origination of the incoming call.

12. A method for controlling routing of a telephone call, comprising the steps of:

on the premises where an intended called party is located, generating in a call processor an accessible list of numbers uniquely identifying calling parties;

associating each said number with a desired destination selected from a plurality of destinations including the intended called party; and

accessing said accessible list of numbers in response to an incoming call and routing the call to the destination referenced in said accessible list of numbers.

13. The method of claim 12, further including generating a look-up table for each of a pluraliy of potential called parties associated with the call processor.

14. The method of claim 12, further including providing access to said call processor by a user thereof for generating said look-up table.

15. The method of claim 14, further including providing capabilities in said call processor for allowing the user to modify the look-up table to thereby change said destinations.

16. The method of claim 12, further including providing capabilities in said call processor for adding identification and deleting identification numbers from said list.

17. The method of claim 12, further includin providing a memory for storing voice prompts input to said call processor by a user thereof for subsequent use by the user in responding to an incoming call.

18. The method of claim 17, further including storing in the memory voice prompts which are transmitted to the called party in response to the incoming call.

19. A call processor for carrying out the steps of claim 12.

20. A method of controlling routing of a telephone call, comprising the steps of:

providing a programming mode in a call processor for allowing a user to whom a call can be directed to program the call processor to control the routing of incoming calls directed to said user; and

providing a program within said call processor for allowing said user to enter calling party identifying indicia and a call route destination associated with each said identifying indicia, the call route desitnation selected from a plurality of destinations including said user and a voice messaging facility.

21. The method of claim 20 further including providing in said program a call processing routine for receiving incoming calls and associated call identification telephone numbers, and comparing the call identification telephone numbers with said preprogrammed calling party identifying indicia to determine the call route for the incoming call.

22. The method of claim 20, further including recording a voice message of a user of the call processor to define a voice prompt for later use in assisting in the call routing of an incoming call.

25. A call processor for carrying out the steps in accordance of the method of claim 20.

23. A method for controlling routing of a telephone call, comprising the steps of:

providing a programming mode in a call processor for allowing a user to program the call processor to control the routing of incoming calls directed to the user; and

providing a program within said call processor for allowing the user to enter calling party identifying indicia and a call route desitnation associated with each said identifying indicia;

storing voice messages associated with respective geographical areas;

matching the call identification number of an incoming call with one said message; and

transmitting said matched message to a called party.

24. The method of claim 23, further including storing an area code as an indication of the geographical area.
