Speed Dial with Side button?

[MPDamon]

Well I have tried searching everywhere. My problem is the lack of voice dialing through the Bluetooth on the Treo. Sprint has a service that lets you dial * Send and the voice dialing is stored on their server. This would work. What I would like to do is have the side button on the treo dial that speed dial. This would call the voice dialing service and a compatable headset would pick up the call. Allowing you to be hands free.

I can't find an application that will allow me to do a speed dial with this button.

Any help would be great. Thanks.
