Summary:                    chan_mobile pairs, dials, and receives calls, but no
audio
Description: 
I am using Asterisk 1.6.2.0~dfsg~rc1-1 from Debian Squeeze with a custom
compiled chan_mobile.c from the trunk version (svn 209993) supplied as an
attachment to issue https://issues.asterisk.org/view.php?id=16087.

It appears to be a working configuration with no obvious errors, but I get
no audio over the bluetooth link.  (I test by calling my cell phone from
the Asterisk console via an IAX provider, with the incoming call going to
an echo test.)

I've attached the Asterisk debugging output (with some IAX debugging
output removed) as well as hcidump -X -V.

---------------------------------------------------------------------- 
Update:  The bluez version in Debian squeeze was recently updated from 4.42
to 4.57.  I tried chan_mobile again, but the symptoms are the same. 
Everything that I can think to look at appears perfectly normal, with no
errors.  In hcidump -X -V the SCO packets are flying by, with silence and
non-silence clearly visible in the data, in the right places.  This
suggests, to me, that the issue is not with the BT dongle.  And yet, there
is no audio making it into or out of asterisk.

I have verified that the phone works with a regular BT headset.

If an asterisk dev can suggest any experiments to probe further, I'm eager
to assist.  I can't see any reason why this shouldn't be working :|
