this is great. i'm glad that at least some manufacturers think "out of
the box" :)

well, it somewhat different scenario. your _phone_ is still connected to
the gsm network and can route audio to either headset or windows pc. its
great that your phone can do that.
what i had in mind is that you have voip hardware/software running on
the pc. so, you can make a voip calls from your pc, just like regular
phone. the scenario i tried to describe is that the cellphone becomes a
headset-like device, i.e. using bluetooth it connects to the pc and
using headset-like protocol request a call (from pc via voip).
now bluetooth headset could either be connected to the cellphone or you
could just connect it directly to the pc, i.e.
<--> IP <--> [voip pc] <-- bt --> [cellphone] <-- bt --> [headset]
^

+-------- bt --> [another headset]
so, the cellphone is acting like proxy giving access to your phone book,
voice commands etc. but making all the calls via voip pc and not gsm.
> Now as far as using voip, I don't know if my cellphone could do that.
the phone does hot have to support voip.
thanks,
max
