[BeenTouched]

It does with the exception of the sound coming out of the rear speakers rather than the front rear ...I guess you should be alright with a BT headset.

Search here or over @ xda forums for WM6Voip for the cab files to get going.

[Personal experience] If you receive poor to little sound on your speakers, you may want to add the following reg key

[HKEY_LOCAL_MACHINE\Security\Phone\VoIP]
"AttenuationClassForRTC"=dword:00000005

HTH,
