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:

I used kiax as the softphone on the same machine asterisk is running. 

Now I tried it with a eyebeam softphone (sip). But the problem that the
bluetooth connection breaks up still appears. I dialed my pstn number and
hung up before we were connected. Then asterisk throws out reason "104"
disconnects and reconnects again. I added again a dump file (hcidebug_sip)
to give you some information. 

My tries with eyebeam showed up the same audio problems. But this time you
can't hear the other person sitting behind the sip phone even the volume
was set to a maximum. 

With kind regards,

Martin
