<p class="MsoNormal">Hello,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal"><span lang="EN-US">We are testing webrtc via mod_verto with the verto_communicator demo. After some initial troubles with certificates, we have it running from Chrome and Firefox. Very nice!<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US"><u></u> <u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">But, when we leave the connection on for some time, the audio in the direction from the browser to a phone becomes increasingly longer. We have clocked ~11 seconds, if we leave it on long enough. The audio in the other
direction has a normal IP telephony delay. We have not found any browser dependencies.<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US"><u></u> <u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">The FreeSWITCH version is 1.10.1 (latest stable release). The phone end has been a Blink softphone, or a trunk from a Cisco UCM. The latter negotiated mulaw PCM with a 20 ms packet size.<u></u><u></u></span></p>

</span></span></span><u></u><span lang="EN-US">CentOS virtualized in VMWare doesn’t have any buildup of delay, and the delay is a normal IP telephony delay.<u></u><u></u></span></p>

</span></span></span><u></u><span lang="EN-US">So, the more Windows, the worse…<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US"><u></u> <u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">I have a Wireshark trace, and I can get a TLS stream from it. I can install a key file to decode the stream, but the configuration wants a protocol, and I don’t know what to enter there. There are no dissectors for Websocket.
So I’m at a bit of a loss, as to how to debug this. I don’t see anything obvious in the freeswitch.log.<u></u><u></u></span></p>

<p class="MsoNormal"><span lang="EN-US"><u></u> <u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">We could package a Linux machine to our customers, but as everything else is on Windows, it would be nice to make it work.<u></u><u></u></span></p>
