Re: [SR-Users] Problem implementing usrloc via dmq

[Aleksandar Sosic]

Hi,

still haven't managed to solve this problem.
Kamailio crashes on call hangup so I do think this is a serious problem.

Kind regards,

Hi,

Glad you solved it - omitting the call to dmq_handle_message() appears to
be a common mistake. I may try to make it clearer in the docs that things
will not work as expected if this is not included.

As for the dialog/dmq integration, I've not had a chance to test it myself.
I will try to take a look later this week!

Cheers,

Charles

Re: [SR-Users] Problem implementing usrloc via dmq

[Aleksandar Sosic]

Hi Charles,

I did solve the problem with

if(is_method("KDMQ")) {
dmq_handle_message();
}

in the main route and the dmq_usrloc is working now.

I enabled dmq for the dialog also:
modparam("dialog", "enable_dmq", 1)

and the dmq is working between kamailio instances but the call does
not end and the kamailio instance where the call was made crashes.

Hello,

Which version of Kamailio?

What is the output of 'kamcmd dmq.list_nodes'?

Cheers,

Charles

[SR-Users] Problem implementing usrloc via dmq

[Aleksandar Sosic]

Hi everyone,

we're trying to make work usrloc over dmq without a db on our nodes.

Our `kamailio.cfg` code to make it work on the nodes is like this:
```
...
loadmodule "usrloc.so"
...
loadmodule "dmq.so"
loadmodule "dmq_usrloc.so"
...
modparam("dmq", "server_address", DMQ_ADDRESS)
modparam("dmq", "notification_address", "sip:routers.ourcloud.com:5060")
modparam("dmq", "multi_notify", 1)
modparam("dmq", "num_workers", 4)
modparam("dmq_usrloc", "enable", 1)
modparam("dmq_usrloc", "sync", 1)
```

Where `DMQ_ADDRESS="sip::5060"` is the public IP address
of the running node.

`nslookup` of  `routers.ourcloud.com`:
```➜  ~ nslookup routers.ourcloud.com
Server:8.8.8.8
Address:8.8.8.8#53

Non-authoritative answer:
Name:rrouters.ourcloud.com
Address: 
Name:routers.ourcloud.com
Address: 
```
and obviously IP1 and IP2 are pubblic IPs of kamailio nodes that
respond to my pings.

When i register a client to node IP1 it's ul dump is:
```
{
   "jsonrpc": "2.0",
   "result": {
  "Domain": "location",
  "Size": 1024,
  "AoRs": [{
 "Info": {
"AoR": "0409828030",
"HashID": 1970914268,
"Contacts": [{
   "Contact": {
  "Address": "sip:0409828030@172.19.0.255:56328;ob",
  "Expires": 289,
  "Q": -1,
  "Call-ID": "5mclwiX4oYAVK0z-iT7M0p9RBX5-02g6",
  "CSeq": 59427,
  "User-Agent": "Telephone 1.2.6",
  "Received": "sip::5060",
  "Path": "[not set]",
  "State": "CS_NEW",
  "Flags": 0,
  "CFlags": 192,
  "Socket": "udp::5060",
  "Methods": 8159,
  "Ruid": "uloc-599d8fa8-f-1",
  "Instance": "[not set]",
  "Reg-Id": 0,
  "Last-Keepalive": 1503498176,
  "Last-Modified": 1503498176
   }
 }]
  }
   }],
   "Stats": {
  "Records": 1,
  "Max-Slots": 1
   }
},
"id": 1
}
```

On node with IP2 the ul dump is:
```
{
   "jsonrpc": "2.0",
   "result": {
  "Domain": "location",
  "Size": 1024,
  "AoRs": [],
  "Stats": {
 "Records": 0,
