Yeah, that's what I did, but even with the patch you reference below for
pwlib, ekiga still barfs trying to open the audio device.  More on that
below, but for now, following your procedure...

I tried your configuration but ekiga complains, on trying to open the
audio devices:

ALSA lib pcm.c:2105:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_sco.so
ALSA lib pcm.c:2105:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_sco.so
ALSA lib pcm.c:2105:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_sco.so

So obviously you have something providing that "sco" pcm module.

Ubuntu Gutsy in fact.

When I use instead:

pcm.headset {
   type bluetooth
   device 00:1A:45:1B:19:89
   profile "auto" #optional, supported profiles are: auto, hifi and voice
}

I can use arecord ... | aplay and I hear myself just fine, but ekiga
pukes out:

ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL headset
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL headset

and I do eventually get a connection and can hear on the headset but the
UI ends up hanging -- doesn't paint.

On a second invocation I get connected to a phone I have dialed but the
connection dies quite quickly and ekiga says:

(ekiga:24243): GLib-GObject-WARNING **: /build/buildd/glib2.0-2.14.1/gobject/gsignal.c:1715: handler `2996' of instance `0x8466978' is not blocked
ALSA lib pcm_bluetooth.c:1179:(bluetooth_cfg) Error 22 while configuring device
ALSA lib pcm_bluetooth.c:1179:(bluetooth_cfg) Error 22 while configuring device
ALSA lib pcm_bluetooth.c:1179:(bluetooth_cfg) Error 22 while configuring device

and I get the warning dialogs about not being able to play or record
from the soundcard.
