My modules.conf.xml config part looks like following:<BR>
<!-- Codec Interfaces --><BR>

<!--<load module="mod_isac"/>--><BR>
<!--<load module="mod_celt"/>--><BR>
<!--load module="mod_opus"/--><BR>
<BR>
Is it a problem with CN definition?<BR>
Could you please lead me where the problem is located?<BR>
<BR>
Thanks in advance.<BR>
