Annoyed with Your Push-to-Talk Button? Re-map it to MS Voice Command.

Not exactly breaking news, but during this flight (Hello again Denver!), I just got around to re-mapping my ATT Tilt's bothersome PTT (Push to Talk) button. You'll need to backup your registry and be enough of a tinkerer to know how to edit the registry in Windows Mobile.

PROCEED AT YOUR OWN RISK. INCORRECTLY EDITING THE REGISTRY CAN KILL YOUR PHONE.

Background:

There is a button on the top left of the HTC Kaiser a.k.a. 8125. With the, "ATT Tilt," branded version of this phone, this button, when depressed, asks something along the lines of, "Are you sure you wish to activate Push-to-Talk? Additional service charges will be incurred."

I'm not a walkie-talkie, "where you at?" kind of guy, so I do not wish to activate and purchase PTT Service. Heck, even if I wanted that capability, I could probably find some freeware IM/Voip app to work just fine, rather than purchase a new "service."

This reminds me- post a comment if you would like me to create a blog post about the Internet Connection Sharing app already built into Windows Mobile. There is no need to purchase a separate "computer" data plan and PC card. With a standard USB cable and Windows Mobile, the functionality is already available.

Here is the good stuff:

Worked for me. You have to read the whole post.
For my own purposes as well, here are the consolidated steps to take. Until someone improves on this, I keep all this stuff in a directory so I can reconfigure my device as necessary. Here goes...

I think the trick is the PTT settings take precedence when the device boots up so delete the PTT registry settings under HKLM/Services/PTT.

Delete the whole sub tree, then
From HKLM\Software\Microsoft\Shell\Keys
Add a new key called "40C6"Add a string under the key called "Name" with the value "Button 6"

Add a new key called "40C7"Add a string under this key called "Name" with the value "Button 6 (hold)"
(Note, do not enter the quotes, thare are to delimit what belongs in the registry entry)

Go to the Buttons settings and assign a program to the new entries. [Crockett note: I use MS Voice Command].

Do a soft reset [Crockett note: use a paperclip or pen to hit the reset button in the tiny pinhole on the bottom of the phone, or take the battery out] which will remove the PTT settings from the buffer and enable your key changes.

Thanks for all the help.

I'd say the only caveat is if you some day want to use the PTT features, it would be a good idea to take an inventory of what is under the PTT node in the registry.
