Hi,
for balancing between kamailia you have to run certain DMQs for state
exchange (registration, hash tables,...). Regarding RTPEngine - you have to
have a failover cluster with Redis, where each RTPEngine will write keys
and at the same time receive the Subscription keyspace of the other
RTPEngines.

Hi Dear Community,
Would appreciate your input into where to look further to explore my
options and would be good to learn your experience with the following.
There are many active-active kamailio nodes behind tcp load balancer. On
the same VM with each Kamailio there is an instance of RTPEngine to manage
Media/Transcoding/Etc for that Kamailio. This scales UP easily - new nodes
just added behind tcp load balancer. To be able to scale down and/or update
node configuration - I'd like to be able to drain sessions/calls properly
and pass any active calls from current Kamailio and RTPEngine to other
nodes.
DMQ is not yet in place, although it's planned.
What would be proper ways of migrating RTP sessions to other RTPEngines?
Caveats?
Also wonder how properly a tcp/tls based SIP session can be passed to
another Kamailio?
Thank you in advance for your input.
Evgenii Buchnev
