We have Softswitches behind NAT. You need to setup Kamailio with RTPPROXY/Mediaproxy just to forward the SIP traffic to my softswitches. No authentication or whatsoever needed. Just routing SIP Trafficproperly through the NAT. 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.
Someone who knows about Kamailio, can finish it in 15 mins.
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!
