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 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.

2. The system of claim 1, 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.

3. The system of claim 1, wherein the key press event comprises a key identifier.

4. The system of claim 3, further comprising a storage device containing an association between the key identifier and the call control function.

5. The system of claim 3, 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.

6. The system of claim 3, 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.
