WLM & Philips 433 VOIP Phone

Hi,
I have the following setup:

Vista 64 Ultimate
WLM 8.5
Philips 433 WLM Voip Phone

I plug in the phone, the pc detects it OK.
The phone functions, I can see contact list, get alerts etc.
I can make a call - it starts, and then either hangs up immediatly, or says
connected but no sound either way. (Trying this with a friend with one doing
exactly them same)

I've checked device manager - exclamation next to 433 phone. Cannot start
Driver - Code 10 - is the error it gives. I'v tried updating but it says
best driver is aready installed.

Anybody any clue? Aparantly this phone is supposed to just work - but
here's 2 that don't!

Thanks
Chris

while ago and they said something about a new driver for the phone, which
they will develop. but this was month ago
