We have Softswitches behind NAT. You need to setup Kamailio with Mediaproxy just to forward the SIP traffic to my softswitches and balance the Load. No authentication or whatsoever needed. Just routing SIP Traffic properly through the NAT in balanced mode. You might also need to reconfig [url removed, login to view] , iptables etc to synchronize the whole thing.
You should discuss with us what you did with Kamailio for our future addition/change to new sip servers.
At the end of project sip connections with real sip trunk will be tested.
Before you begin you will get our network schematic which is pretty simple and you should provide us with tipps about where to add the Kamailio server.
I Appreciate your response!
in short your tasks:
1. we have server A & Server B loaded with Asterisk and Billing software. You install Kamailio and Mediaproxy to a Third server.
2. You configure Kamailio+ mediaproxy to spread traffic in 50%-50% basis and solve NAT related problems.
[url removed, login to view] need to edit our SRV records for Load Balancing for Mediaproxy and Kamailio
4. you might have to tweak [url removed, login to view] / iptables
5. at the end of the project you explain us the whole stuff as we will be adding a second kamailio/mediaproxy server in Ative/Passive with Heartbeat to the Server you will configure.
