Hi Daniel and list,
I'm integrating xmpp module to kamailio 3.0.4 with the component mode on my local network.
Kamailio: sip.htk.com
Jabberd: xmpp2.htk.com
With your diagram as the previous mail:
xmmp-user ------- xmpp-server ------ xmpp-to-sip-gateway
------- sip-to-xmpp-gateway -------- sip-server ------- sip-user
