Can you confirm if the TALK/NOTALK events are even firing? Try listening to all events and then sifting through the barrage of data to see if those events are present. If they are then you know you just have a filtering issue. If they are not present then you know there&#39;s an issue with VAD or something like that.<br>

Hi, I&#39;m having some issues getting TALK / NOTALK events to fire on an incoming stream to Freeswitch. In my ESL application I am subscribing to RECORD_START RECORD_STOP TALK NOTALK, Below is the dial plan I am using:<br>

<br>
&lt;extension name=&quot;teliax-in&quot;&gt;<br>
&lt;condition field=&quot;destination_number&quot; expression=&quot;^(5555551212)$&quot;&gt;<br>
&lt;action application=&quot;set&quot; data=&quot;rtp_enable_vad_in=true&quot;/&gt;<br>
&lt;action application=&quot;set&quot; data=&quot;rtp_enable_vad_out=true&quot;/&gt;<br>
&lt;action application=&quot;set&quot; data=&quot;fire_talk_events=true&quot;/&gt;<br>
&lt;action application=&quot;set&quot; data=&quot;fire_not_talk_events=true&quot;/&gt;<br>
&lt;action application=&quot;playback&quot; data=&quot;ivr/ivr-hello.wav&quot;/&gt;<br>
&lt;action application=&quot;record&quot; data=&quot;/tmp/data.wav&quot;/&gt;<br>
&lt;/condition&gt;<br>
&lt;/extension&gt;<br>
<br>
I can see that VAD is enabled:<br>
<br>

<br>
<br>
In my ESL app I get the RECORD_START and RECORD_STOP but not the talk events.  I&#39;m on git  version &quot;2c52f23 2012-02-18 08:37:47 -0600&quot;, Any ideas?  Thanks.<br>
