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:

Hi guys, I have tested the latest trunk version of addons (r823) and there
are some relevant issues:

- chan_mobile.so can't be loaded, there is an error on
ast_string_copy(chan->exten, "s", AST_MAX_EXTENSION);  should be
ast_copy_string...

- There is a synchronization problem (I think) with write/read of AT
commands : randomly asterisk 1.6.1-branch-r184387 crashes with a
segmetation fault sending ATD or Hangup. I have also tried with other
asterisk versions.


Now the audio connection quality is very good and dtmf recognition works
well.
Soon I'll give you all details of my tests.
