I want to do a simple call server

Could anyone direct me to some config help? I’m using Mandriva 2007 and urpmi installed asterisk. I have a bunch of avaya ip phones (46xx) and want to make a lab setup where they just communicate with each other (no dialing out, just each other). Is there an easy way to do this? Or could I be pointed to a sample config. I added the extensions and attempted to use the h323 conf file. Should I be using sip instead? (I tried h323 because i noticed the ip phones would try to contact the linux server with asterisk referencing an h323gate)

thanks kindly.
