Hi Yufei, 

I've tried to do that but unfortunately i'm facing a weird issue.

I have nodes on probing mode, but dispatcher only sends probing via one of the sockets and then, in some cases, wrongfully updates the status of the elements of the pair.

I've even tried to manually disable one of the Dipsatcher destinations, first the one with the VIP and then the other, and Kamailio still sends requests via one of the sockets, usually the second in the list. 
This only happens if i have two destinations with same IP but different sockets. In scenarios with different IP and different sockets it all works correctly.

I'm currently on Kamailio v5.4.1. What version are you on? Any special parameter to make that work? 

Best Regards,

Greetings, 

I have two machines with Kamailio in a HA setup with replicated DB. For simplicity let's say each machine has one HA IP and that IP can jump to the other machine in case something happens (kamailio stopping, etc).

I'm using Dispatcher with load balance configuration. I have Dispatcher configured so that each peer has one instance for socket with HA IP 1 and HA IP 2.

In order for this to work correctly on the load balance scenario I must disable via RPC command the peer which has the socket that doesn't belong to the machine. I also must do it every time the IP jumps back and forth, which adds complexety to my system.

Does Dispatcher has any sort of help on this? It could not include peers with sockets IPs that don't belong to the machine in the destination set, for example. Is this possible?

I could also work with failover support but i would rather avoid having so many failovers.

Best Regards,A
