Hi Daniel, Maybe you can share with me full config of your load-balancer? It will be really nice if I can take a look on it. I'm very new in kamailio and for me is very difficult to complile working config from short code snippets. :)
You mentioned that you have 2 load-balancer. Does this 2 load-balancers share one domain-name? I was thinking to use dispatcher module for load balancing. Do you use dispatcher module in your config?
