[Freeswitch-users] wrong detection dtmf rfc2833

[Yuriy Nasida]

it depend from your  incoming sip provider as well.did you try to detect dtmf  for incoming calls  in media stream (inband)  instead of using rfc2833 ? <param name="dtmf-type" value="none"/>  - on  incoming  sip profile<action application="start_dtmf" /> - in dialplan before bridge

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?
