Abstract

In a Computer Telephony Integration environment, a method of, and system for, registering the identity of a telephone terminal in association with the identity of a computer terminal, in which a host computer requests a user, via a screen display on the computer of his workstation, to declare the number of the telephone which he wishes to be registered in association with his computer. When the user answers a call made to that telephone from the CTI-enabled PBX by command of the host computer (the CTI server of the registration system) and dials or speaks a codeword, this is received at the PBX and reported to the host computer, and the telephone is registered as associated with the computer terminal provided that the reported codeword matches the codeword provided to the user. By calling the telephone presumed to be associated with the computer and verifying the association upon successful comparison of the codewords, the registration process is independent of the telephone identifying itself via CLI to the registration system and thus the user can be situated in a remote country, or connected to a PSTN which does not support the transmission of CLI.

Claims

1. A method of registering the identity of a telephone terminal in association with the identity of a computer terminal, the method comprising the steps of:

receiving from a user of a computer terminal a telephone number of a telephone terminal which that user wishes to have registered in association with the identity of that computer terminal;

making a call to that received telephone number;

providing to the user, via that computer terminal, a codeword;

answering by the user the call made to that received telephone number;

receiving data via that telephone terminal after that call has been answered;

comparing the received data with the provided codeword; and

if there is a match, registering that received telephone number in association with the identity of that computer terminal.

2. A method as claimed in claim 1, including the steps of starting a timeout when the call is made, and sending a termination message to that computer terminal in the event that the timeout expires before the call is answered.

3. A method as claimed in either claim 1 or claim 2, including the step of checking whether the received telephone number is a member of a list of authorised telephone numbers for that user.

4. A method as claimed in any one of claims 1 to 3, wherein the user provides said telephone number via his computer terminal in response to an invitation sent to that computer terminal.

5. A method as claimed in claim 4, wherein the codeword is provided in combination with the invitation.

6. A method as claimed in either claim 4 or claim 5, wherein the invitation is sent in response to a failure to receive at a predetermined destination number a calling line identity in respect of that telephone terminal when the user had dialled that predetermined destination number.

7. A system for registering the identity of a telephone terminal in association with the identity of a computer terminal, the system comprising:

means to receive from a user a telephone number of a telephone terminal which that user wishes to have registered in association with the identity of that computer terminal;

means responsive to receipt by the receiving means of that telephone number to make a call to that received telephone number;

means to provide to the user, via that computer terminal, a codeword;

means to receive data provided via that telephone terminal;

means to compare the received data with the provided codeword; and

means responsive to a match between the received data and the provided codeword to register that received telephone number in association with the identity of that computer terminal.

8. A system as claimed in claim 7, including means responsive to the making of the call to start a timeout, and means responsive to the expiration of the timeout to send a termination message to that computer terminal.

9. A system as claimed in either claim 7 or claim 8, including means for checking whether the received telephone number is a member of a list of authorised telephone numbers for that user.

10. A system as claimed in any one of claims 7 to 9, including means for sending to that computer terminal an invitation for the user to provide said telephone number via his computer terminal, and wherein said means to receive from a user a telephone number is arranged to receive said telephone number provided via that computer terminal.

11. A system as claimed in claim 10, wherein the means for providing the codeword is arranged to provide the codeword in combination with the invitation.

12. A system as claimed in either claim 10 or claim 11, wherein the means for sending an invitation is responsive to a failure to receive at a predetermined destination number a calling line identity in respect of that telephone terminal when the user had dialled that predetermined destination number.

13. A method of registering the identity of a telephone terminal in association with the identity of a computer terminal, the method being substantially as herein described with reference to the drawing.

14. A system for registering the identity of a telephone terminal in association with the identity of a computer terminal, the system being substantially as herein described with reference to and as shown in the drawing.
