[SR-Users] Building Up a Kamailio Server

Hi Everyone, I am totally new to Kamailio & going to build up Kamailio server as an XMPP server with the following wanted functionalities:  -Have XMPP client to register to my kamailio server - The XMPP clients should all be able to see each others presence - The XMPP clients should be able to IM other XMPP clients - The registered sip client will be able to just dial any other sip client. No need for any gateway or trunk for now  I have a good previous background with SIP but its my first time to work with XMPP & Kamailio & that's why I am in need of a bit help & assistance. I have installed Kamailio on my CentOS box & now going to start to configure it in order to complete the above requirements, so any links or any refferals will be highly appreciated.   Regards, Faisal Rehman
