problem with full duplex voicce Tx on freerunner

[TARUN CHAPLOT]

Hi,
Wanted to add some more details to my previous post.  We are having a
problem with running PJSIP on the neo freerunner, and have tried a
variety of solutions to fix this but still not successful.   The setup
that we are using is PJSIP on a Mac with OSX, and PJSIP compiled for
openmoko.I compiled PJSIP for openmoko by setting the env using command
source /usr/local/openmoko/arm/setup-env
and ./configure --host=arm-angstrom-linux-gnueabi.

When we run PJSIP between the Mac and Openmoko, we are encountering two
problems.  

The first is that only sound from the Mac goes to the Openmoko, when we
speak into the Openmoko, there is no sound output from the Mac.   I have tried 
already to fix this - such as incorporating the
state (1)voip-handset.state  (2) voip-headset.state 
files in /usr/share/openmoko/scenarios/ for full duplex.
I have also tried with different settings in alsamixer as well. 



The second problem is that the sound quality is very bad. When we speak
into the Mac, the sound coming from the Openmoko comes out in stutters
(on and off every half second). It is also full of static.  When we try
a VOIP call directly from mac to mac, it works and sounds fine.  
Further, I recorded a .wav file on Mac OS X and freerunner to auto answer the sip call. 
 The recorded .wav file on Mac sounds good enough  while the file of freerunner   stutters a 
lot and sounds like its missing some packets in between at some interval.
For reference I am providing the link to get that recorded wav file of freerunner.

So far nothing works well.
Thanks in advance for any kind of help.

 Hello
I am using neo freerunner and have problem with the sound . The voice quality is very bad and its not full duplex.
Please advise me on that so that I can make some  proper changes to my phone to get better sound quality.

What kind of tests I can do for checking that my mic and speakers working properly.

Any help would be greatly appreciated.

Thanks a lot.

Tarun
