Abstract

A method and apparatus for call completion using information extracted from an active application on a computing machine is described. Call initiation may be accomplished using a “warm-line” feature in which a default number is dialled after a predetermined time of an off-hook condition of a voice terminal, if no digits are dialled after the voice terminal is taken off-hook. The number dialled is a number used to connect the telephone set to computer-Controlled Telephony Integration hardware (CTI). On receipt of the call, the CTI hardware extracts Automatic Number Identification (ANI) information to determine the number of the calling party and verifies that the calling party is the subscriber to the service. If the calling party is the subscriber to the service, a query is sent to an IP address associated with the subscriber to retrieve information from an active application for completing a second leg of the call. The information may be a telephone number, or information which would permit the retrieval of a telephone number such as a name and address or an e-mail address. A directory service may be used to convert the information into a telephone number. Once a telephone number is obtained, the CTI hardware is used to complete the second leg of the call and the two calls are joined together. The advantage is a fast, convenient method of completing calls without dialling digits or manually converting one form of information into a diallable number.

Claims

establishing a first voice connection between the first voice terminal and a predetermined termination;

locating a data address for a computing machine associated with the first voice terminal after the voice connection is established with the predetermined termination;

sending a data message to the data address requesting that information be retrieved from an open application on the computing machine;

retrieving the information from the open application and returning a data message including the information;

using the information at the predetermined termination to establish a second voice connection with the second voice terminal; and

bridging together the first and second voice connections.

2. A method of completing a voice connection between first and second voice terminals as claimed in claim 1 wherein the first voice terminal, or a telephone switch to which the first voice terminal is connected, is adapted to automatically dial a predetermined number if at least one other digit is not dialled within a predetermined period of time after the first voice terminal is changed from an on-hook to an off-hook condition.

3. A method of completing a voice connection between first and second voice terminals as claimed in claim 1 wherein the first predetermined termination is with voice connection switching circuits controlled by a server.

4. A method of completing a voice connection between first and second voice terminals as claimed in claim 3 wherein the server determines the identification of the first voice terminal using calling line identification to obtain a telephone number associated with the first voice terminal.

5. A method of completing a voice connection between first and second voice terminals as claimed in claim 4 wherein the server uses the telephone number associated with the first voice terminal in a table look-up to determine the data address associated with the first voice terminal.

6. A method of completing voice connection between first and second voice terminals as claimed in claim 5 wherein the data address is an Internet Protocol IP address of the computing machine and the computing machine is connected to an IP network which may be accessed by the server.

7. A method of completing a voice connection between first and second voice terminals as claimed in claim 6 wherein software active on the computing machine receives the data message from the server and searches a current page of the open application for the information.

8. A method of completing a voice connection between first and second voice terminals as claimed in claim 7 wherein the information retrieved from the current page is an e-mail address which is sent in the return message to the server.

9. A method of completing a voice connection between first and second voice terminals as claimed in claim 8 wherein the e-mail address is used by the server to retrieve a telephone number from a directory service to permit the server to complete the voice connection with the second voice terminal.

10. A method of completing a voice connection between first and second voice terminals as claimed in claim 8 wherein the e-mail address is used by the server to retrieve an Internet Protocol (IP) address from a directory service to permit the server to complete a Voice over Internet Protocol (VoIP) connection with the second voice terminal.

11. A method of completing a voice connection between first and second voice terminals as claimed in claim 1 wherein the first voice connection between the first voice terminal and a predetermined terminating end is initiated with a speed-dial key on the first voice terminal.

12. System for completing a voice connection between first and second voice terminals, comprising in combination:

computer-controlled telephony hardware adapted to receive and to originate calls;

a server adapted to control the telephony hardware and determine an identification of the first voice terminal on receipt of a call from the first voice terminal, to determine a data address of a computing machine associated with the first voice terminal, and to send a message to request that information be retrieved from an application open on the computing machine;

means on the computing machine for receiving the message, retrieving the information from the open application and returning the information in a reply message to the server; and

means for receiving the reply message, completing a voice connection with the second voice terminal from the telephony hardware using the information, and bridging together the first and second voice connections.

13. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 12 wherein the first voice terminal is connected to a private branch exchange and the private branch exchange is programmed to dial the computer-controlled telephony hardware if a digit is not dialled within a predetermined time period after the first voice terminal is changed from an on-hook to an off-hook condition.

14. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 12 wherein the first voice terminal is connected to a switching node in a switched telephone network and the switching node is programmed to dial the computer-controlled telephony hardware if a digit is not dialled within a predetermined time period after the first voice terminal is changed from an on-hook to an off-hook condition.

15. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 12 wherein the first voice terminal has a speed-dial feature and a one of the speed-dial numbers dials the computer-controlled telephony hardware.

16. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 12 wherein the server determines the identification of the first voice terminal using a calling line identification feature provided by a switched telephone network service provider.

17. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 12 wherein the server is adapted to determine whether the first voice terminal is associated with a subscriber and to disconnect the first voice terminal if the first voice terminal is not associated with a subscriber recognized by the server.

18. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 12 wherein the data address associated with the first voice terminal is determined in a table lookup in which the identification of the first voice terminal is associated with the data address.

19. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 12 wherein the server uses a directory service to convert the information received in the reply message to an address for completing the voice connection with the second voice terminal.

20. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 19 wherein the information comprises an e-mail address.

21. Apparatus for completing a voice connection between first and second voice terminals as claimed in claim 20 wherein the e-mail address is converted to a telephone number retrieved from the directory service.
