Hello, seems you use round robin algorithm. You can use hash over call id if you want that same path is preserved for same Call-ID value. If you want to use round robin, you have to use htable to store where the INVITE was sent first time, and when it comes second time with auth credentials, use the address from htable instead of dispatcher.

Below is how the call is being process. user kamailio 1proxy 2proxy user2 invite |----------> | 100 | <---------- | invite | | ---------> | 100 |<--------- | auth |<-----------| auth | <------------------------| ack |------------->| ---------->| Invite |-------------->| --------------------------> | then process Is there any I can limit this? or it is realy the behavior?
