Yes, but...

For Bluetooth devices, the appropriate gremium defined profiles,
specifying capabilities for certain device types and how those shall
interact. Most mobile phones seem to implement the phone profile
allowing to connect a headset profile device. Obviously those are
different specs! And I did not yet find a mobile phone that implements
the headset profile correctly.

A possible alternative could be running a full blown SIP client on those
phones that support it. There is SIP client software for at least
Windows CE, I do not know wether Palm, Java phones or whatever will
work. Of course this is only reasonable if your phone supports wireless
802.11 or another means of over-the-air networking (leaving bluetooth,
GPRS is not interesting for SIP transport).

A pity that Windows CE seems to NOT support Bluetooth TCP/IP networking,
at least in those two incarnations that I ran into. It seems mobile
network providers do not like their customers to have an alternative
choice besides GPRS data transfer :-/

I would love to hear if there are phones that actually implement the
headset part.

Regards,
Anselm
