I have been investigating distributing incoming/outgoing SIP traffic to behind Kamailio SIP  servers in order to scale and other advantages too!.

SRV type distribution is not a good option, it is already tested.

So,  I am trying to deploy Kamailio as a LoadBalancer in Tier1 , so it distributes traffic backbone Kamilio servers in Tier 2. There is a good presentation as follows, actually I want to implement it.

However, I could not find sample configurations and sample study ! Would you show me sample configurations that Kamailio uses as a Load Balancer if you have it.

Current Kamailio responsibilities in my system are:

 1. Registar Server  
 2. Presence Server
 3. Sip proxy server  
 4. WebSocket 

Maybe it will be very good to separate  Registar Server &  Presence Server, but could not find sample configurations too. 

Best Regards

P.S.  If we could collect such configurations, I would share them for community on Github.
