Seg fault on opening the config window

Use instead the standard library gsm (libgsm1, libgsm1-dev).
cf www.sflphone.org/index.php?file=Dependencies.txt

After intalling the libraries libgsm1 and libgsm1-dev, you can create the shared library codec_gsm.so with:
gcc -shared -o codec_gsm.so gsmcodec.cpp -lgsm

Audio calls with ilbc codecs still not tested.

You have to copy the codec_ilbc.so in /usr/lib and make ldconfig

Note: Manually copy the .so library in /usr/lib , then ldconfig

Copier les librairies dynamiques (codec_*.so) dans le répertoire /usr/lib et upda
faire ldconfig

Add a class codec on client side to manipulate codec-related data.
Add a screen that displays on call the number called and the codec used.

note: the screen doesn't display when a call is made with the keypad. TODO

The combo box displays the default or the selected codec

The user can select a codec among the supported one's in the audio settings tab of the config window.
The call is made with only this codec.

TODO: use the other supported codecs to place a call, if the selected one doesn't work
