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.
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 and a working Jabberd2 server serving domain 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"
...
loadmodule "XMPP.so"
...
modparam("xmpp", "backend", "component")
modparam("xmpp", "domain_separator", "*")
modparam("xmpp", "gateway_domain", "sip.uniza.sk")
modparam("xmpp", "xmpp_domain", "xmpp-sip.uniza.sk")
modparam("xmpp", "xmpp_host", "server.xmpp.uniza.sk")
modparam("xmpp", "xmpp_password", "secret")
...
#main routing logic
route {
...
 if( uri=~"sip:.+[*].+@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@sip.uniza.sk
SIP client from XMPP view: sip_client*sip.uniza.sk@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@xmpp-sip.uniza.sk' id='mir_47' from='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
