you're right, thx. And the link has this! It needs CVS sdp and stuff, 
and I have no clue how to use it, but it seems to work.

IIUC, not true. C link.

Guess what. Think about it. Doom - for them. Goodbye to insane 
telecommunication costs. KILLER linux feature. Wooooooooow, awesome ;==)
For that, please someone who can actually code talk to them, merge it 
into bluez and so. As said, I have absolutely no clue how to just use 
it, so I won't be even taking the time to compile it. I'll wait till 
it's covered by the bluez-utils ebuild + deps. :==P

Oh yeah, stop.. all the euphory - but still the audio stream needs to be 
grabbed without the /phone/ actually opening a connection. Hope this is 
hackable.
so long guys.

Hi Marcel,
Maybe I haven't explain myself... I don't know what you have found at 
the link Lars gave, I only see that there is a implementation of the 
headset profile in BlueZ (so you could speak to the laptop and the 
laptop would make a bluetooth link to the phone, which is connected to 
the GSM network)... but what we need in order to use a phone as a 
headset is not found in this link, at least I can't find it! :c)

Re: [Bluez-devel] Re: possible to use phone itself as headset?

[Brad Midgley]

Hi

There is a profile (I forget the name) that allows for the phone to use 
a sort of bluetooth access point for its connection to the phone 
network. No one implements it however. And it is voice-quality mono.

I don't think any handset will do what you want out of the box, but if 
you're good at programming inside symbian maybe you could make one of 
the symbian phones do it. I suppose that's beyond the level of effort 
you were hoping for.

I think you mean CTP (cordless telephony profile)

As I said in previous thread, I think NONE actual mobile phone would let 
us hook the audio streaming from/to the microphone/speaker to/into a SCO 
channel. Telephone Companies have some power at phones market.

so everybody and his brother believes this to be impossible then? Well, 
in that I'll get myself another headset. Thx everybody for answers.
