<p>Hello,</p>
<p>maybe not directly related to the issue, but could be better to
separate rtpengine on its own system, likely it requires less
failover scenarios, so active calls are not affected at all if you
have to do a failover for the signaling server...</p>
<p>Anyhow, as you trigger a failover and you know it is not going to
recover the active calls, you can close them via dialog module.</p>
<p>Cheers,<br>

<div>I use CentOS 7.4.x with kamailio 5.0.5 and
rtpengine on a pacemaker/corosync cluster</div>
<div>in front of an internal kamailio siprouter and
media-services.</div>
<div><br>
</div>
<div>If i did an "pcs node standby" to failover my
frontend-kamailio (udp/tcp 5060, udp/tcp 5061-tls
and tcp websocket-secure) i noticed the following
scenarios:</div>
<div><br>
</div>
<div>1) Plain RTP: just stocks a few seconds and
flows. Everything fine.</div>
<div>2) SDES/RTP: silence - but REINVITE manually in
my client brings audio back. Need improvement.</div>
<div>3) DTLS/RTP WebRTC: silence - all clients shows
an active call. I know that there is NO way to
recover this call - because of the temporay DTLS
certificate due the rtpengine start-up.</div>
<div><br>
</div>
<div><br>
</div>
<div>So i thought - for scenario1) i dont need
anything to do. Works nice.</div>
<div>For scenario2) i need something to "remember its
SDES/RTP calls and send them an REINVITE"</div>
<div>And for scenario3) i should just hangup all
WebRTC calls - IMHO the best for that.</div>
<div><br>
</div>
<div>How can i fire-up these tasks to get an
"clean-up" or "reinvite" after an failover?</div>
<div><br>
</div>
<div>
<div><br>
</div>
<div>scenario legend:</div>
<div>
<div>1) unencrypted call</div>
<div>2) TLS/SDES encrypted call</div>
<div>3) DTÖS WebRTC encrypted call</div>
