[SR-Users] DMQ problems

[Aleksandar Sosic]

Hi,

I've set up a dmq server for other kamailio nodes with this parameters:
```
modparam("dmq", "server_address","sip:10.0.0.101:5060")
modparam("dmq", "notification_address", "sip:127.0.0.1:5060")
modparam("dmq", "multi_notify", 1)
modparam("dmq", "num_workers", 4)
modparam("dmq", "ping_interval", 15)
```

On the kamailio nodes the config is the following:
```
modparam("dmq", "server_address", "sip:10.0.0.x:5060")
modparam("dmq", "notification_address", "sip:10.0.0.101:5060")
modparam("dmq", "multi_notify", 1)
modparam("dmq", "num_workers", 4)
modparam("dmq", "ping_interval", 15)
```

On the kamailio dmq server I've got this in the logs:
```
25(41) ERROR: dmq [notification_peer.c:596]:
notification_resp_callback_f(): deleting server sip:127.0.0.1:5060
because of failed request
25(41) ERROR: dmq [notification_peer.c:599]:
notification_resp_callback_f(): not deleting notification_peer
```

On the kamailio nodes the same thing with the ip of the dmq server:
```
25(112) ERROR: dmq [notification_peer.c:596]:
notification_resp_callback_f(): deleting server sip:10.0.0.101:5060
because of failed request
25(112) ERROR: dmq [notification_peer.c:599]:
notification_resp_callback_f(): not deleting notification_peer
```

The request route on the dmq server is simple as this:
```
request_route {
if(is_method("KDMQ")){
dmq_handle_message();
}
}#end request_route
```

I've tried with some xlog-s inside the if(is_method("KDMQ")) but they
don't show up so the dmq_handle_message() is not even executed.

I've also tried to bind the dmq server to a different port but with no
success on making it work.

The dmq.list_nodes shows only the dmq server IP and the current node
IP, the IPs of other nodes are not shown:
```
root at proxy-94b6ccf46-t8fx2:/# kamcmd dmq.list_nodes
{
host: 10.0.0.101
port: 5060
resolved_ip: 10.0.0.101
status: active
last_notification: 0
local: 0
}
{
host: 10.0.0.45
port: 5060
resolved_ip: 10.0.0.45
status: active
last_notification: 0
local: 1
}
```
And it's the same on all other kamailio nodes: dmq server ip and local ip.

The kamailio version on all the nodes is:
5.2.0~dev6+0~20180616010152.1138+xenial
