<br>
      &lt;condition field=&quot;${switch_r_sdp}&quot; expression=&quot;a=rtpmap:(\d+)\stelephone-event/8000&quot; break=&quot;never&quot;&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;rtp_payload_number=$1&quot;/&gt;<br>
        &lt;anti-action application=&quot;start_dtmf&quot;/&gt;<br>
      &lt;/condition&gt;<br>
<br>
This will look at the SDP and toggle on start_dtmf if no telephony-event is present in the inbound invite.<br>

&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=&quot;dtmf-type&quot; value=&quot;rfc2833&quot;/&gt;<br>
&gt;<br>
&gt; Where I need to add start_dtmf parameter for detecting in-band DTMF ?<br>
&gt; We are using  dialplan.xml file located in root of conf folder<br>
&gt; &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;<br>
&gt; &lt;include&gt;<br>
&gt;   &lt;context name=&quot;public&quot;&gt;<br>
&gt;   &lt;extension name=&quot;SYFreeSwitch&quot;&gt;<br>
&gt;   &lt;condition field=&quot;destination_number&quot; expression=&quot;.*&quot;&gt;<br>
&gt; &lt;action application=&quot;start_dtmf&quot; /&gt;<br>
&gt;   &lt;action application=&quot;managed&quot; data=&quot;SYFreeSwitch&quot;/&gt;<br>
&gt;   &lt;/condition&gt;<br>
&gt;   &lt;/extension&gt;<br>
&gt;   &lt;/context&gt;<br>
&gt; &lt;/include&gt;<br>
&gt;<br>
&gt; It&#39;s right place for it ?<br>
&gt;<br>
&gt;<br>
&gt; Thank you in advance,<br>
&gt;<br>
