In case it was not clear from the previous email - this only happens with conferences. If after the beep, instead of placing the call into a conference, I just play some music, there are no problems. On Sat, May 31, 2014 at 5:46 PM, Oleg Stolyar <olegstolyar@gmail.com> wrote:
Hi guys,
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:
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.
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.
This absolutely does not happen with softphones - only with WebRTC. I tried it with Chrome and Opera - same thing is happening on both.
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.
Has anyone run into this? Any advice?
Here is the relevant excerpt from my dialplan.
<condition field="destination_number" expression="^conf-(\S+)$"> <action application="set" data="answer_delay=3000"/> <action application="answer"/> <action application="playback" data="tone_stream://%(1000,0,600)" /> <action application="conference" data="$1@default"/> </condition>
