Re: [SR-Users] SIP-XMPP problem, please help

8 Apr 2011


      Hello,
you can allow traffic sent by kamailio to itself, in the auth route, 
just add in the first position:
if(src_ip==myself)
    return;
Cheers,
Daniel

So this way Kamailio will forward incoming XMPP messages after 
translation to SIP and they dont have to be authenticated. The 
authentication of the SIP MESSAGE was the problem. All other types of 
SIP requests will have to be authenticated, except for MESSAGE request.
I fear this is not so corrent solution, but it is working. IM msgs 
flow both directions (SIP->XMPP, XMPP->SIP) now.
If anyone knows how to get kamailio authenticate messages from XMPP, 
please, let me know. I would be very gratefull.
Good luck to you all.

By the way ... I forgot to change my real domains in the logs ....
"p2b.sip.uniza.sk <http://p2b.sip.uniza.sk>" is "sip.uniza.sk
<http://sip.uniza.sk>" and user "katka" is "SIP_client"

    Why is Kamailio doing a DNS SRV query for himself after he has
    recieved a message from XMPP and translated it to SIP ??

        Hello,

        if you run kamailio with debug=3, what log messages are
        printed when the xmpp message arrives to kamailio?

        Cheers,
        Daniel

        Hello everyone.
        I am a student at University of Žilina (Faculty of
        Management Science and Informatics), which has been
        recently awarded Kamailio 2010 Awards for various
        articles about SIP and KAMAILIO on portal nil.uniza.sk
        <http://nil.uniza.sk>.
        I am doing a bachelor thesis on topic SIP/SIMPLE - XMPP
        traversal, but I am experiencing some problems.
        I have a working Kamailio server serving domain
        sip.uniza.sk <http://sip.uniza.sk> and a working Jabberd2
        server serving domain xmpp.uniza.sk <http://xmpp.uniza.sk>.
        I am running Kamailio 3.1 with XMPP module with following
        configuration:

        fork=yes
        children=4
        log_stderror=yes
        alias="sip.uniza.sk <http://sip.uniza.sk>"
        ...
        loadmodule "XMPP.so"
        ...
        modparam("xmpp", "backend", "component")
        modparam("xmpp", "domain_separator", "*")
        modparam("xmpp", "gateway_domain", "sip.uniza.sk
        <http://sip.uniza.sk>")
        modparam("xmpp", "xmpp_domain", "xmpp-sip.uniza.sk
        <http://xmpp-sip.uniza.sk>")
        modparam("xmpp", "xmpp_host", "server.xmpp.uniza.sk
        <http://server.xmpp.uniza.sk>")
        modparam("xmpp", "xmpp_password", "secret")
        ...
        #main routing logic
        route {
        ...
         if( uri=~"sip:.+[*].+@sip.uniza.sk <http://sip.uniza.sk>")
                {
                        # absorb retransmissions ###
                        if (!t_newtran())
                        {
                                sl_reply_error();
                                return;
                        }
                        if (method == "MESSAGE")
                        {
                                log("*** xmpp-handled MESSAGE
        message.\n");
                                if (xmpp_send_message())
                                {
                                        t_reply("200", "Accepted");
                                } else
                                {
                                        t_reply("404", "Not found");
                                }
                                return;
                        } else
                        {
                                t_reply("403","not supported");
                                exit;
                        }
                }
        ...
        }

        To my knowledge there is no configuration required on the
        Jabberd2 server (except the password, that the XMPP
        component authenticates with).
        I am trying to enable SIP clients to chat with the XMPP
        clients and vice versa.
        SIP clients can send messages to XMPP clients. XMPP
        modules translates SIP to XMPP and forwards the massage
        to Jabberd2 server.
        URIs look like:
        XMPP client from SIP view: xmpp_client*xmpp.uniza.sk
        <http://xmpp.uniza.sk>@sip.uniza.sk <http://sip.uniza.sk>
        SIP client from XMPP view: sip_client*sip.uniza.sk
        <http://sip.uniza.sk>@xmpp-sip.uniza.sk
        <http://xmpp-sip.uniza.sk>
        The message arrives to XMPP client, but he can not reply.
        I have sniffed the traffic on the Kamailio server. The
        XMPP message arrives to kamailio XMPP module (correct
        port and everything), but the module somehow ignores it,
        doesn't translate XMPP to SIP and doesn't send it to the
        SIP recipient.
        The sniffed message looks like:

        <message xmlns='jabber:client' type='chat'
        to='SIP_client*sip.uniza.sk
        <http://sip.uniza.sk>@xmpp-sip.uniza.sk
        <http://xmpp-sip.uniza.sk>' id='mir_47'
        from='XMPP_client@xmpp.uniza.sk/Miranda
        <http://XMPP_client@xmpp.uniza.sk/Miranda>'><body>hello</body></message>

        Any suggestions on where can the problem be ??
        Do I have to add some lines to routing logic for XMPP
        module to process the XMPP message (from Jabberd2) for
        SIP_client ??

        Thanks
        Martin
