[Kamailio-Users] Kamailio as proxy and Asterisk as registrar

Hi all! Kamailio newbie here. Well my setup is like this Kamailio as load balancer and proxy -> Multiple clustered asterisk as registrars What I wanted to do was have all clients registered to asterisk so that most of the pbx stuff will be done thru it and I'm using Asterisk Realtime as well and doing A2billing at the same time so I was thinking if my setup will actually work. I have already configured kamailio to do load balancing and send to my asterisk servers and my xlite is able to register to my asterisk server, the problem I have right now is when I try to call, the call gets dropped. I believe it's something about asterisk not being able to send the correct INVITE or not being able to receive the ACK or something to that effect. Please help me, as I've said I'm just a newbie with kamailio. TIA!
