Charles,

I have the follwing parameters configured:

# ----- dmq params -----
modparam("dmq", "server_address", "sip:10.10.10.1:5060")
modparam("dmq", "num_workers", 4)
modparam("dmq", "ping_interval", 90)
modparam("dmq", "notification_address", 
"sip:sip04.voip.domain.test:5060")

And the output of dmq.list_nodes is:

{
         host: 10.10.10.2
         port: 5060
         resolved_ip: 10.10.10.2
         status: active
         last_notification: 0
         local: 0
}
{
         host: sip03.voip.domain.test
         port: 5060
         resolved_ip: 10.10.10.1
         status: active
         last_notification: 0
         local: 0
}
{
         host: sip04.voip.domain.test
         port: 5060
         resolved_ip: 10.10.10.2
         status: active
         last_notification: 0
         local: 0
}
{
         host: 10.10.10.1
         port: 5060
         resolved_ip: 10.10.10.1
         status: active
         last_notification: 0
         local: 1
}


As you can see the nodes are listed twice, one time with the ip and one 
time with the hostname. If i change the notification_address to a ip 
address the duplicate entry's are gone.

Thanks,

Jan
