[Freeswitch-users] Fix - IGNORE INFO DTMF(3) (This channel was not configured to use INFO DTMF!)

I am using WebRTC of FreeSWITCH with latest codes to fix some issues. But i am stuck with this annoying WARNING showing:

2014-01-22 10:18:04.869529 [WARNING] sofia.c:7746 IGNORE INFO DTMF(3) (This channel was not configured to use INFO DTMF!)

I changed in the switch settings as mentioned in the doc: http://wiki.freeswitch.org/wiki/Sofia.conf.xml#DTMF , but still i get this same error. <param name="dtmf-type" value="info"/> or <param name="dtmf-type" value="rfc2833"/> or <param name="dtmf-type" value="none"/> or <param name="liberal-dtmf" value="true"/> Can anyone kindly advise how to fix it please? Thank you Best regards IamTrying
