[Bluez-users] Telephony with BT headset?

Hi everyone,

I have a BT headset lying around which came with my mobile
phone. However, I don't use it with my mobile, so the idea
crossed my mind that it could be possible to use the
headset with my linux server to make phone calls using
the ISDN system.

I'm quite sure that this _is_ possible, as I can receive
and send an audio stream via ISDN4Linux, and the same
applies (more or less) to the headset via BlueZ.

The question is now whether there is already some soft-
ware to achieve this, or whether I'll have to start
from scratch (BTW: is there any FAQ on how to send and
receive audio streams from a BT headset?)

Yours, Florian

There is a telephone application http://www.antcom.de/ant-phone/ which I
have tried with a cable headset.

There is also some BT headset driver for ALSA
http://www.dcs.gla.ac.uk/~jp/snd-bluez-sco/ which I haven't tried (yet).

Regards.
Matthias

has anyone tried this application with the capidrv? For example with a
AVM B1. I own one, but mine is build into the wrong machine for such
tests and I need it there. I run some tests with a BlueFRITZ! AP-ISDN
and call management stuff seems to work, but I don't hear anything on my
soundcard.

Is there anyone who will spend some time in adding native CAPI support
to this application?

Regards

Marcel

In my setup, I used capidrv and a BlueZ cmtp connection to a BlueFritz! 
AP-X (and a cable-headset), and it worked although I got large 
latencies. Also see my post(s) at the ant-phone mailing list:

I guess Roland has to be asked this :) I cross-post this to his mailing 
list as well.

Regards.

This is definitely on the TODO list. I hope to get more time for this
soon.

Feel free to contribute. Unfortunately, ant-phone is currently quite
/dev/ttyI* based.

bye,
  Roland
