Hi: I have followed wiki: http://wiki.freeswitch.org/wiki/Enterprise_deployment_OpenSIPS To deploy OpenSIPS in front of FreeSWITCH. I have played with the load balancer part before, so I know how that works. I have now been able to register through the OpenSIPS to FreeSWITCH box via the dispatcher module of OpenSIPS. But what happened is that the registration IP is the IP of the OpenSIPS server, not the end user's IP address. I am wondering how would we process incoming call for the registered user? Obviously the call will be routed back to the OpenSIPS server with an invite, which gets processed by the load balance module according to the script. So what I am asking is that is this a logic flaw in the original script? or did I misunderstood it? If it is a flaw, does any one know how to fix the senario? Because I am not that good with OpenSIPS to fix it.
