Abstract

A method for collecting information from a user of a telephone includes receiving a request at a switch in a telephone network to open a voice call from the telephone to a specified telephone number. Responsively to the request, a voice call is initiated by opening a first leg of a connection from the switch to the telephone, and a second leg of the connection from the switch to a peripheral device. The second leg is disconnected after initiating the voice call, while leaving the first leg of the connection open. After disconnecting the second leg, signals are received over the first leg of the connection responsively to one or more keystrokes made by the user on the keypad of the telephone.

3. The method according to claim 1, wherein the telephone network comprises a circuit-switched telephone network, operating in accordance with a Signaling System 7 (SS7) protocol.

4. The method according to claim 1, wherein receiving the signals comprises reporting the keystrokes to a service control point (SCP).

5. The method according to claim 4, wherein reporting the keystrokes to the SCP comprises generating mid-call events at the switch in response to the keystrokes, and conveying the mid-call events over the telephone network to the SCP.

6. The method according to claim 4, wherein receiving the request comprises, responsively to the specified telephone number, reporting the request to the SCP, and wherein initiating the voice call and disconnecting the second leg comprise controlling functions of the switch responsively to instructions from the SCP.

7. The method according to claim 4, and comprising conveying data from the SCP to a server indicative of the keystrokes made by the user, and tabulating the data at the server.

8. The method according to claim 1, wherein receiving the request comprises presenting the user with a prompt on a medium unconnected with the telephone, the prompt soliciting a reply from the user by means of a telephone call to the specified telephone number, and wherein the signals are indicative of at least one keystroke made by the user in response to the prompt.

9. A method for collecting information from a user of a telephone having a keypad, the method comprising:

presenting the user with a prompt on a medium unconnected with the telephone, the prompt soliciting a reply from the user by means of a telephone call to a specified telephone number;

receiving a request at a switch in the telephone network to open a voice call from the telephone to the specified telephone number;

responsively to the request, opening a connection with the telephone over the telephone network; and

receiving signals over the connection responsively to one or more keystrokes made by the user on the keypad of the telephone, indicating the reply to the prompt presented on the medium.

10. The method according to claim 9, wherein opening the connection comprises opening a second leg of the connection from the switch to a peripheral device, and disconnecting the second leg after initiating the voice call, while leaving the first leg of the connection open for receiving the signals responsively to the one or more keystrokes.

11. The method according to claim 10, wherein the peripheral device comprises an audio response device, and wherein initiating the voice call comprises receiving an audio reply from the audio response device in response to opening the second leg of the connection.

12. The method according to claim 9, wherein the telephone network comprises a circuit-switched telephone network, operating in accordance with a Signaling System 7 (SS7) protocol.

13. The method according to claim 9, wherein receiving the signals comprises reporting the keystrokes to a service control point (SCP).

14. The method according to claim 13, wherein reporting the keystrokes to the SCP comprises generating mid-call events at the switch in response to the keystrokes, and conveying the mid-call events over the telephone network to the SCP.

15. The method according to claim 13, and comprising conveying data from the SCP to a server indicative of the keystrokes made by the user, and tabulating the data at the server.

16. The method according to claim 15, wherein tabulating the data comprises computing an output value based on the data, and comprising displaying the output value on the medium.

17. The method according to claim 16, wherein receiving the request comprises receiving multiple, respective requests from multiple users to open simultaneous voice calls to the specified telephone number, and wherein opening the connection comprises opening multiple simultaneous connections responsively to the requests, and wherein receiving the signals comprises receiving keystroke inputs from the multiple users over the simultaneous connections, and wherein computing the output value comprises tabulating selections made by the multiple users in response to the prompt, as indicated by the keystroke inputs.

18. The method according to claim 17, wherein the medium comprises a television medium, and wherein presenting the user with the prompt comprises providing the prompt in a television program, and wherein displaying the output value comprises presenting the output value on the television program following the prompt.

19. Apparatus for collecting information from a user of a telephone having a keypad, the apparatus comprising a service control point (SCP), which is adapted to receive a first message from a switch in a telephone network, indicative of a request received by the switch to open a voice call from the telephone to a specified telephone number, and responsively to the first message, to initiate a voice call by causing the switch to open a first leg of a connection from the switch to the telephone and to open a second leg of the connection from the switch to a peripheral device,

wherein the SCP is further adapted to instruct the switch to disconnect the second leg after initiating the voice call, while leaving the first leg of the connection open, and to receive a second message from the switch indicative of signals received at the switch over the first leg of the connection responsively to one or more keystrokes made by the user on the keypad of the telephone after disconnecting the second leg of the connection.

20. The apparatus according to claim 19, wherein the peripheral device comprises an audio response device, and wherein initiating the voice call causes the audio response device to issue an audio reply in response to opening the second leg of the connection.
