[SR-Users] RTP voice failover

[Yufei Tao]

Hi,

RTP FO is possible, e.g. with keepalived+rtpengine+Redis as people
suggested.

Here's the guide for configuring it which I find very useful:
https://github.com/sipwise/rtpengine/wiki/Redis-keyspace-notifications

A possible way is to have a pair of rtpengine instances in master-slave
setup. When master goes down, RTP continues on slave (new master) after a
few seconds gap, when the virtual IP(s) migrate over.

Another useful link:

Good luck!
