I have configured a conference on new installation of freeswitch, every
thing works fine voice quality is good when lady says that "You are the only
one in this conference" and music but as soon as other party get connected
and started to talk voice get choppy/noisy nothing can be understood, like
if someone says "HELLO" other party listen jerking noisy
voice  like "---$H^----#E at ----%LL^----*O&"

I am new to Freeswitch please guide me that how I can fix
/ troubleshoot this issue or let me know if need some debugging etc...
