For example, I have four kamailio instance for register, one kamailio instance recv REGISTER, it copy to other three kamailio instance by dmq_usrloc. In this scene, I set notification_address to domain sip:ka.ns.com:5060 which resolve to all four kamailio instance(which recv REGISTER).In this way, **I do not need to build a separate kamailio cluster only for notification server.**
``` modparam("dmq", "server_address", "sip:10.6.1.200:5260") modparam("dmq", "notification_address", "sip:ka.ns.com:5260") # This configuration, ka.ns.com only resolve to 10.6.1.200, kamailio can not normal start. it report : dmq [notification_peer.c:345]: add_server_and_notify(): error adding notification node dmq [dmq.c:299]: child_init(): cannot retrieve initial nodelist from sip:ka.ns.com:5260 ```
