[SR-Users] implementing Kamailio with FreeSwitch.

Hello and thanks for your helping,excuse me I'm newbie in mailing list. I have a question about implementing Kamailio with FreeSwitch. Our plan is a configuration like this at the follow: 1.Kamailio as registering and LoadBalancer ,response to chat and call(voice/video) in p2p 2.we have 2 FreeSwitch media engine just for Conference case(Voice/Video) . How we can implementing above kamailio as loadBalancer for 2 FreeSwitchs in conference case , And at the same time,It answer as voip/chat server for p2p case ? we have success by implementing Kamailio with one FreeSwitch, (FreeSwitch as media Engine just for conference and Kamailio for p2p call) But if we have 2 FreeSwitch with same activity,How we can implementing... And So I had Efforts with dispatcher module, but it was good only for route/Loadbalancer not for answering p2p call. Thanks a lot Mehdi Badiezadegan
