Summary:                    Poor audio quality and sometimes disconnection after
hangup
Description: 
Some information about my system:
OS Ubuntu 7.04
Bluez: 3.9-0ubuntu1
Bluetooth: Internal Bluetooth from Acer C110 Notebook
Asterisk: SVN-trunk-r83834
chan_mobile: Revision 451
Cellphone: Nokia 6230i

These things are working:
1. Notebook and Nokia are paired
2. Outgoing call from iax phone -> asterisk -> pstn works
3. Incoming call not tested
4. Incoming/outgoing SMS are working

The problem:
At the time the pstn phone picks up the call from the cellphone, you can
hear the person sitting behind the iax softphone very quiet and with a
really poor audio quality. It sounds like a robot is speaking to you. 

My tries to solve the problem:
In mobile.conf:
forcemaster set to no and yes
alignmentdetection set to no and yes
Set the iax softphone to gsm and ulaw

Another problem:
Sometimes after hangup the call the connection between asterisk and the
cellphone breaks up. I don't know why? See this for more information:

Hello,
I retested the disconnect after hangup issue with latest trunk of both
asterisk and chan_mobile. The issue is still there. Can this be connected
with
http://bugs.digium.com/view.php?id=11566 ?

With this line commented out it works:

                               if (strstr(buf, "OK") || strstr(buf,
pvt->ciev_call_0)) {
                                        /* close(pvt->sco_socket); */
                                        pvt->sco_socket = -1;
                                        pvt->state = MBL_STATE_IDLE;
                                }

If some other thread used pvt->sco_socket and it was closed, but not yet
set to -1, it could possibly do something unintended.
