Chrome collects ICE candidates (from two net interfaces: ethernet and wifi), sends them to Freeswitch and Freeswitch accepts one of this candidates. After that Freeswitch tries to make DTLS handshake, but Chrome ignores it and sends STUN pings over and over again. But if I disable one of this network interfaces, then everything works fine. From my point of view the problem is that Freeswitch uses wrong ICE candidate (it takes this candidate from STUN pings, but there is no exactly such candidate in SDP). I also admit that may be the root of the problem is inside Chrome (because Firefox works properly in this case), but I interested in possible explanations an may be solutions from the Freeswitch side. <u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><p class="MsoNormal"><b>Versions</b><br>Freeswitch 1.6.9, 1.6.10<br>Chrome 52, 53, 54<u></u><u></u></p><div><p class="MsoNormal">Server OS: CentOS 7.2.1511<br>Client OS: Ubuntu 16.04<u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal"><b>IP addresses</b><u></u><u></u></p></div><div><p class="MsoNormal">1) 172.15.1.1 -
