<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'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'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'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><condition field="destination_number" expression="^conf-(\S+)$"><br>
