Abstract

A button box provides additional keys that can be used in conjunction with a telephone. In one embodiment, a button box is configured by associating it with a telephone and by programming its keys. When a key on the button box is activated, a key press event is sent from the button box to the associated phone. The phone treats the key press event as if a key on the phone itself had been activated and forwards the event to the voice switch appliance associated with the phone. (Alternatively, the key press event is sent from the button box directly to a voice switch appliance.) The button box'"'"'s user interface is controlled by a voice switch appliance.

Claims

1. A button box device configured to enable a user to invoke a call control function, comprising:

a key to which the call control function has been assigned;

a display; and

a key press event module configured to send a key press event via a packet-switched network

wherein the button box device does not comprise an audio input device.

2. The device of claim 1, further comprising a user interface module configured to receive user interface instructions via the packet-switched network.

3. The device of claim 1, wherein the key press event module is further configured to send the key press event to a switch via the packet-switched network.

4. The device of claim 3, wherein the key press event module is further configured to send the key press event to the switch via a telephone.

5. The device of claim 1, wherein the display is configured to indicate the call control function assigned to the key.

6. The device of claim 1, wherein the key is programmable.

7. A button box device configured to enable a user to invoke a call control function, comprising:

a key to which the call control function has been assigned;

a display;

a key press event module configured to send a key press event to a first switch; and

a user interface module configured to receive user interface instructions from a second switch.

8. A system configured to enable a user to invoke a call control function using a button box device, comprising:

a switch configured to receive a key press event via a packet-switched network and to determine a call control function associated with the key press event; and

a button box device configured to send the key press event via the packet-switched network.

9. The system of claim 8, further comprising a telephone, wherein the telephone is configured to receive the key press event via the packet-switched network and to send the key press event to the switch, and wherein the button box device is configured to send the key press event to the telephone.

10. The system of claim 8, wherein the key press event comprises a key identifier.

11. The system of claim 10, further comprising a storage device containing an association between the key identifier and the call control function.

12. The system of claim 10, further comprising a storage device containing multiple associations between the key identifier and a call control function, wherein the key press event further comprises a button box identifier, and wherein the button box identifier indicates one association of the multiple associations.

13. The system of claim 10, further comprising a storage device containing multiple associations between the key identifier and a call control function, wherein the button box device is associated with a telephone, and wherein the telephone is associated with the user, and wherein an identity of the user indicates one association of the multiple associations.

14. A method for configuring a button box device, comprising:

storing a first association between the button box device and a switch, the switch configured to control a user interface of the button box device;

storing a second association between the button box device and a telephone, the telephone configured to receive a key press event from the button box device; and

storing a third association between a key of the button box device and a call control function, the call control function being invoked when the key is activated.

15. A method for enabling a user to invoke a call control function using a button box device, comprising:

receiving a key press event from the button box device;

determining a call control function associated with the key press event; and

executing the call control function.

16. The method of claim 15, wherein receiving the key press event from the button box device comprises receiving the key press event from the button box device via a telephone.

17. The method of claim 15, wherein the key press event comprises a key identifier.

18. The method of claim 17, wherein determining the call control function associated with the key press event comprises identifying an association between the key identifier and the call control function.

19. The method of claim 18, wherein the key press event further comprises a button box identifier, and wherein identifying the association between the key identifier and the call control function comprises identifying the association between the key identifier and the call control function based on the button box identifier.

20. The method of claim 18, wherein the key press event further comprises a button box identifier, and wherein the button box device is associated with a telephone, and wherein the telephone is associated with the user, and wherein identifying the association between the key identifier and the call control function comprises identifying the association between the key identifier and the call control function based on an identity of the user.
