[SR-Users] Re: Kamailio behind TLS-TCP load balancer

Hi Karsten, interesting scenario, thanks. Regarding TLS off-loading its of course less useful then.

Jonas Swiatek gave that as tipp to me. He simple setup self-signed certs on the Kamailio behind the NLB loadbalancer. So it's Internet -> TLS NLB/AWS loadbalancer -> TLS self-signed Kamailio. Should solve your problems. Kind regards Karsten Horsmann Henning Westerholt <hw@gilawa.com<mailto:hw@gilawa.com>> schrieb am Sa., 12.

As you probably know, SIP as a protocol is not really suited for this kind of cloud balancing infrastructure, which targets more HTTP and other protocols. And Kamailio in a load-balancer scenario is usually the first TLS/TCP/UDP endpoint to reach from the client point of view.

Everything else inside is UDP. I found I need to manually add record-route presets every time and invite comes in. And when trying to forward an ACK to the client via tls/tcp load balancer Kamailio complaint the socket is not TLS so it fails. Is there a simpler way of doing this via some parameters I don’t know? Thanks for helping me with this!
