Hello List,

and also an happy new year to everyone.

I use CentOS 7.4.x with kamailio 5.0.5 and rtpengine on a pacemaker/corosync cluster

in front of an internal kamailio siprouter and media-services.

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:

1) Plain RTP: just stocks a few seconds and flows. Everything fine.

2) SDES/RTP: silence - but REINVITE manually in my client brings audio back. Need improvement.

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.

So i thought - for scenario1) i dont need anything to do. Works nice.

For scenario2) i need something to "remember its SDES/RTP calls and send them an REINVITE"

And for scenario3) i should just hangup all WebRTC calls - IMHO the best for that.

How can i fire-up these tasks to get an "clean-up" or "reinvite" after an failover?

scenario legend:

1) unencrypted call

2) TLS/SDES encrypted call

3) DTÖS WebRTC encrypted call
