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?
