[SR-Users] IMS server with a core network

hello, I posted a message in the kamailio forum but it wasn't in the good place, so I rebroadcast at this e-mail as it was say. Hello, I have installed Kamailio 4.2 and I would like to use it as IMS server but I don't have any ideas how to do this. I have a LTE core network which includes HSS ans PCRF. I saw on this page ( http://www.kamailio.org/w/2013/05/ims-kamailio/ ) that is apparently easy, just need to take the P-CSCF, S-CSCF and I-CSCF Kamailio and Diameter config files in the examples folder and run kamailio but I don't know how to use them and I didn't find any tutorials about it. Could you help me please ?
