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:

phokz,
when I tested Nokia 6230i, there was a problem with incoming calls: sound
always goes to mobile speaker, not to Asterisk. Have you noticed such a
behavior?
If not, I guess something was wrong with mobile firmware or my version of
bluez-lib.
By the way, the only model (of http://bugs.digium.com/view.php?id=14#20 tested)
I've found which supported all
features of chan_mobile was Nokia 6021 (( Mostly, they don't support sms.
