Good day!

I have problem with dtmf on incoming calls.

Internal dtmf work normal, but on incoming call i have many mistakes 
(111  or 121 instead 110, for example).

siptrace wrong detection attached, Abonent send 110, but freeswitch 
detect 111.

in profile's config i set these options. (Im trying many variants, but 
no find solution)

<param name="dtmf-duration" value="2000"/>
<param name="dtmf-type" value="rfc2833"/>
<param name="rfc2833-pt" value="0"/>
<param name="liberal-dtmf" value="true"/>

Have you any ideas?
