Hi Aidar,

Your approach should work. So basically calls from Asterisk should be routed to destination what is found in location table and calls not from Asterisk to Asterisk servers.

Try update your config following way:

change "route(DISPATCH);" line with flowing code:

if(!ds_is_from_list()) {

        route(DISPATCH);
}

Additionally you can save registrations on Asterisk side using path.

My sample config using path:

With kind regards,

Jurijs

This seems to be an Asterisk issue and not Kamailio issue.


In particular, it seems that you haven't set up your peer configuration in Asterisk in such a way that it matches towards the Kamailio context.


I would suggest that you do a verbose console connection to the Asterisk and check which context the INVITE ends up in.


Most likely you will need to change the peer type and perhaps identify it by IP so it doesn't have to register.

Subject: [SR-Users] kamailio 5.0 with asterisks
 
Hello!

I'm new with kamailio, so may be don't understand some basic.
I'm tryin to load balance asterisk servers with kamailio and dispatcher module. My ip phones registered at kamailio, for example:

[root@sipchel ~]# kamctl ul show 101
{
  "jsonrpc":  "2.0",
  "result": {
    "AoR":  "101",
    "Contacts": [{
        "Contact":  {
          "Address":  "sip:101@192.168.2.62;line=4733c4bfa459eea",
          "Expires":  2953,
          "Q":  -1,
          "Call-ID":  "1361221648",
          "CSeq": 136,
          "User-Agent": "Linphone/3.6.1 (eXosip2/3.6.0)",
          "Received": "[not set]",
          "Path": "[not set]",
          "State":  "CS_SYNC",
          "Flags":  0,
          "CFlags": 0,
          "Socket": "udp:192.168.10.54:5060",
          "Methods":  -1,
          "Ruid": "uloc-596f5abc-2ce5-2",
          "Instance": "[not set]",
          "Reg-Id": 0,
          "Last-Keepalive": 1500530337,
          "Last-Modified":  1500530337
        }
      }]
  },
  "id": 15024
}


I have realtime asterisk server.
[root@sipchel ~]# kamctl dispatcher dump
{
  "jsonrpc":  "2.0",
  "result": {
    "NRSETS": 1,
    "RECORDS":  [{
        "SET":  {
          "ID": 1,
          "TARGETS":  [{
              "DEST": {
                "URI":  "sip:192.168.4.16",
                "FLAGS":  "IX",
                "PRIORITY": 0
              }
            }, {
              "DEST": {
                "URI":  "sip:192.168.10.47",
                "FLAGS":  "AX",
                "PRIORITY": 0
              }
            }]
        }
      }]
  },
  "id": 15087
}


So I want if 101 call to 102 it will process by asterisk(for call recording and other features). Now if I call from 101 to 102 kamailio will forward to asterisk and asterisk dialplan cannot find that extesion(as expected, because it is not registed on asterisk)
[kamailio]
exten => _1XX,1,Dial(SIP/${EXTEN})
exten => _1XX,n,Hangup
If I change dialplan to Dial(SIP/KAMAILIO/${EXTEN}) call wil return to kamailio, but kamailio send it back to asterisk...

I hope I explained correctly, my English is terrible.
Is my screnario proper? How this usually done? Should I forward sip registrations to asterisks?
