[Freeswitch-users] how is codec selected

[Zohair Raza]

Hi,

You can find it in sofia.conf.xml

For ngrep, you need to have ngrep installed in your system

try "yum install ngrep" if you are using CentOS/RedHat and "apt-get install
ngrep" if Ubuntu

Yes, you need to make a call, as you want to know which codecs are being
carried from leg A to FS and FS to Log B

Regards,
Zohair Raza
