Hello, I was looking to implement HA with 2 Kamailio machines. I am aware of the dmq module and I thought that would be a great place to start. The problem I see is that dmq module does not have any "failure" callback mechanism. For instance, if KamA sends dmq ping to KamB, and KamB does not respond (perhaps because it's down), then nothing happens. I looked into using the dmq API and checked the dmq code to see how send_message() function works, and I dont see any indication that there is a failure callback. I would be a great improvement to add this sort of functionality to dmq and then other modules or code can be written to use the API to detect when another Kam box is up or down. This could lead to another module like dmq_ha (I'm open to writing this)
Thanks, V
