Ingredients: IPAQ H4355, Jabra BT200, XTEN XLITE soft-SIP phone.

This nice IPAQ model has no microphone jack, so I have to get the Jabra to play with it in both directions (outgoing with the earphone, incoming with the microphone). I am not too familiar with bluetooth and was really surprised to find that there is no Plug-n-Pray.

The Jabra BT200 works with certain bluetooth phones and Jabra tech support does not want to know anything about anyone trying to connect to another device. So, I have made a change to the registry and I get the outgoing (earphone) to work (sort of... I get test sounds but not an application playing through it yet). This is pretty well documented on the net...

set HKLM\Software\widcomm\BtConfig\Services\0005\Enabled to 1

But, no microphone. So, I have no microphone showing up as a registered bluetooth device and the earpiece is not really working. And I am wondering... is this my beautiful PDA?

Lots of people try this (myself included). I didn't get good results at all, and it seems it's only available for speaker, not for mic. Also you have to change a .dll that is used for sound in some other place in the registry.

Funny thing is that I was playing with X-Ten yesterday. I have a couple of Cisco IP phones in my desk now for some testing, and a SIP gateway (yes with real POTS connection!). I can place calls using SJPhone, but the voice path is not connected. With X-Ten I can't place the calls at all. X-Ten on my laptop works fine though.

If you don't need POTS connectivity at this moment, you have to try PocketSkype. It's superb quality, and works with wi-fi and Bluetooth LAN access.

I can see your desk from here. We have POTS going into our Asterisk SIP gateway, just one Cisco 7960, a few yucky Grandstreams, a Clarisys USB handset working nicely with XTEN Pro. And then a few more of the same out there in our homes.

BUT, I still want to get this IPAQ H4355 working right. It actually works very well with the XTEN all things considered but the sound quality leaves a lot to be desired. That's why I am trying to force the BT200 headset to work with it.... very determined about this. So pls, if you can tip me in the right direction... I will be most grateful.

Hmmm. Very cool.

Anyway. I've change this on my Pocket PC, but got no good results at all:

HKLM\Software\widcomm\BtConfig\Services\0005\Enabled changed to 1

HKLM\Drivers\BuiltIn\WaveDev\Dll changed to to BtCeIf.dll (make sure you write down your current one!)

It appears that some users report very unstable Pocket PC after the change on Wave Device...

I put it aside for a few days and now have the Jabra headset registered as an Incoming & Outgoing BT device. Now, any ideas as to how to get the applications to route to it instead of the internal microphone and speaker? TIA!

Can any of you guys managed to get it work? I tried changed the registry as shown above and I only get hissing sound and that all. Many concern now is to use Jabra for headset like listen to mp3.

I didn't have any success in using a Bluetooth headset with the h4150. First it's not user friendly, since it's not support by the software without some non-standard changes in configuration. Second it'll not give high quality sound. For your MP3 playing needs it'll be not optimal, since it's only a mono connection, not stereo.
