<HTML><BODY><P>I'm trying to use codec2 in FS. But it only generates a noise. There is a comparasion of speex and codec2 in attached files. The source is the demo_ivr in default configuration [\conf\lang\en\demo\demo-ivr.xml :: <macro name="demo_ivr_main_menu" pause="100">].<BR>FS version = 1.2.11. OS = CentOS 2.6.32-358.18.1.el6.x86_64.<BR>As I understand there is no configuration of codec2 in FS?<BR>So, what it can be? Why it does not work?</P></BODY></HTML>
