[SR-Users] blf in kamailio dmq cluster

[Aidar Kamalov]

I have some kamailio servers in each city: city1.example.com,
city2.example.com, city3.example.com.
Users in city1 connects to city1.example.com.

each kamailio has in config:
alias="city1.example.com"
alias="city2.example.com"
alias="city3.example.com"

modparam("dmq", "server_address", "sip:LOCALIP:5050")
modparam("dmq", "notification_address", "sip:city1.example.com:5050")
modparam("dmq", "notification_address", "sip:city2.example.com:5050")
modparam("dmq", "notification_address", "sip:city3.example.com:5050")
modparam("dmq", "num_workers", 6)
modparam("dmq_usrloc", "enable", 1)
modparam("dmq_usrloc", "sync", 1)

        if(is_method("PUBLISH")) {
                handle_publish();
                if(!dmq_is_from_node()) dmq_t_replicate();
                t_release();
        } else if(is_method("SUBSCRIBE")) {
                handle_subscribe();
                if(!dmq_is_from_node()) dmq_t_replicate();
                t_release();
        }


When publish from city1.example.com replicated to city2.example.com, PUBLISH
sip:34200 at city1.example.com SIP/2.0 but there is no 34200 at city1.example.com
in active_watchers table there is  34200 at city2.example.com. So when publish
is coming to city2.example.com handle_publish can not found it, and doesn't
send NOTIFY.

Is it any way to ignore domain part in handle_publish()?
