&gt; Hello !<br>
&gt;<br>
&gt; I am a new in Freeswitch..<br>
&gt; I need a help with start_dtmf parameter<br>
&gt;<br>
&gt; We have IVR system (Telephone Reporting System)<br>
&gt; Some times in incoming calls Freeswitch misses some key presses (DTMF)<br>
&gt; I guess that the problem is the detection of DTMF...<br>
&gt; I use in (external.xml)<br>
&gt; &lt;param name="dtmf-type" value="rfc2833"/&gt;<br>
&gt;<br>
&gt; Where I need to add start_dtmf parameter for detecting in-band DTMF ?<br>
&gt; We are using &nbsp;dialplan.xml file located in root of conf folder<br>
&gt; &lt;?xml version="1.0" encoding="utf-8"?&gt;<br>
&gt; &lt;include&gt;<br>
&gt; &nbsp; &lt;context name="public"&gt;<br>
&gt; &nbsp; &lt;extension name="SYFreeSwitch"&gt;<br>
&gt; &nbsp; &lt;condition field="destination_number" expression=".*"&gt;<br>
&gt; &lt;action application="start_dtmf" /&gt;<br>
&gt; &nbsp; &lt;action application="managed" data="SYFreeSwitch"/&gt;<br>
&gt; &nbsp; &lt;/condition&gt;<br>
&gt; &nbsp; &lt;/extension&gt;<br>
&gt; &nbsp; &lt;/context&gt;<br>
&gt; &lt;/include&gt;<br>
&gt;<br>
&gt; It's right place for it ?<br>
&gt;<br>
&gt;<br>
&gt; Thank you in advance,<br>
&gt;<br>
