Try to install SNGREP command line application. It greatly helped me to understand what was going on in kamailio.Install it in your Kamailio server, and run it. You will then be able to see and understand all SIP requests and responses.Also, as Daniel said, the SIP requests between client->kamailio->asterisk must be kept the same at all times when trying to register. Additionally, install Asterisk with Realtime module, and share the same SIP users across your asterisk boxes, by the means of a DB. This is the best approach.Hope this helps,Sérgio Charrua

In your configuration there are couple of things to have in mind: need to set correct flag param
https://kamailio.org/docs/modules/5.5.x/modules/dispatcher.html#dispatcher.p.flags
select the algorithm used to select the destination (ds_select_dst) and have a faulure_route where the next destination will be tried in case first is down.You can find the examples in the module doc.

All users are created in both of the asterisk servers. I am forwarding the registration to asterisk. The problem is that it is always used on only one server from the list. Even if one goes to shutdown, then there is not any registration sent to the available server. Even if some of the extensions can be seen registered in both of the asterisk's, if the secondary goes down, then there are no services for the phones.I am attaching the kamailio.cfg. My dispatch list is:In both of the asterisk servers i am using sip.conf to create users and s sip trunk for the Kamailio. Nothing special about it.I am looking to find what is wrong with my config and i cannot loadbalance/failover to the asterisk servers.
