<div dir="ltr">Hi guys,<div><br></div><div>I am connecting to FreeSWITCH using WebRTC and after a user calls in, I play a beep and put them into a conference.  Two strange things happen after that:</div><div><br></div><div>


1. There is a noise in the user&#39;s leg that someone described like a wind in the tunnel.  The noise lasts for several seconds, then the user can hear the hold music.  The noise does not seem to happen if I don&#39;t play the beep before the conference.</div>


<div><br></div><div>2. About 3 seconds into the call, there is another very short beep - like a small portion of the original beep that the user hears.</div><div><br></div><div>This absolutely does not happen with softphones - only with WebRTC.  I tried it with Chrome and Opera - same thing is happening on both.</div>


<div><br></div><div>I tried increasing the answer delay from 2 seconds to 3 and the noise now happens more rarely but the extra beep is still there almost every time.  I am using JsSIP 3.0 but since it only handles signalling I don&#39;t think the problem is with the JS library.</div>


<div><br></div><div>Has anyone run into this?  Any advice?</div><div><br></div><div>Here is the relevant excerpt from my dialplan.</div><div><br></div><div>&lt;condition field=&quot;destination_number&quot; expression=&quot;^conf-(\S+)$&quot;&gt;<br>


</div><div>        &lt;action application=&quot;set&quot; data=&quot;answer_delay=3000&quot;/&gt;<br></div><div><div>      <span style="white-space:pre-wrap">        </span>&lt;action application=&quot;answer&quot;/&gt;</div>
<div>        &lt;action application=&quot;playback&quot; data=&quot;tone_stream://%(1000,0,600)&quot; /&gt;</div><div>        &lt;action application=&quot;conference&quot; data=&quot;$1@default&quot;/&gt;</div><div>&lt;/condition&gt;</div>
