We currently have 2 Kamailios servers at different locations both share same Db with A2billing. We need registered users on one Kamalio Servers to be able to call registered users in the other Kamalio Server. OpenVpn seemed to be the best way to send traffic between servers. But if you have better solution we will use that.
Kamalio Servers are currently working perfect users can call each other within same server but cannot call registered users on the other server THERE IS NO ROUTE So we need the best way to make a route
