Hi all,

I started to work on bluetooth audio stuff a while ago, and wrote the 
original headsetd implementation that ended up its life in the plugz 
repository. :-)

These days i work on the official audio service on the bluez project. 
The good news is that the Bluez project is starting to have good support 
for headsets, bad news is the focus is really on A2DP (multimedia 
streaming), not on voice support. :-(

If you wish to play with a headset for ekiga, you have to go to plugz, 
as the Bluez audio service is not as advanced as plugz is regarding 
voice headsets.

In the long run it might end up that audio service works with ekiga, but 
that will typically take some time as nobody's pushing for it :-(

Having sayd that, there are a number of issues, that makes Ekiga 
integration with wireless quite painfull:
  - device enumeration with ALSA does not work with pcm plugins, which 
means the headset does not appear in the devices list. I wrote a patch 
for pwlib to fix that, but this is really a hack, as it hardcodes the 
device string with no knowledge of its presence whatsoever :-(
  - Ekiga has the bad habit to close/open the multimedia stream quite 
often : e.g. it would close the alsa device after each ringtone. This 
does not work with BT headsets as they make a special very noisy "bip" 
after the multimedia stream is closed
  - Ekiga does not support when an ALSA device disappears from the 
scene, this ends up with an Ekiga crash :-(

So the path to proper bluetooth support in Ekiga is still a long ride,
however i think this will greatly improve when the audio service 
supports Pulseaudio: it could possibly solve all of the above issues :-)

I hope it brings some lights to the discussion,
