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.

Could you describe for me what is happening in line 5 of the excerpt
above,

[Nov 27 14:29:45] DEBUG[12247]: chan_mobile.c:1357 rfcomm_connect:
connect() failed (4).

?  I.e. what is this connection used for?  I thought the rfcomm channel
would be for the AT command dialog with the phone.  But that dialog is
going just fine even with this rfcomm failed connection.  Is this rfcomm
connection failure somehow related to the next error, in do_sco_listen?

I realize you may not have any idea how to fix this in chan_mobile (if
indeed that is possible), but I do need to understand the sequence of
events better in order to pursue this further.  It could be a problem in
bluez, but I can't expect the bluez folks to dive in until I can explain
exactly what is happening and how it deviates from the expected behavior.

Thanks,

Mark
