[SR-Users] Kamailio with dispatcher and asterisks real time

Hi all folks, Hello people, I'm new and I've been reading, so I have some but not much knowledge. I must integrate as work, two asterisk to the kamailio, a month ago I started with the real time guide [1] with only one kamailio, register, start the call, etc.. I am with the basics and it works. Now I must put two asterisk and using dispatcher, but although I read the documentation of the module.. use it and so then configure a list of file (with the asterisk where to dispatch) and not in the database.. MY HELP REQUEST QUESTION: How do I use dispatcher in load balancing mode, but taking in consideration my already working realtime-asterisk worling setup? THE PROBLEM: since with what I did it simply sends the call to both asterisk. i setup only 4 easy steps.. load module, then setup params (where i set the asterisk lists by file, and not db) and then added a "ds_select_dst(1, 4);" before the "route(RELAY);" line. please help! as i know.. the ds_select_dst(1, 4); prepare wicht asterisk will be choose to use and then when the routing RELAY happends no cares if in the realtime previously guide are a main asterisk? right? NOTE: I know it's a big world... but I can't keep reading the kamailio theory, i must goon forward due i have to lear later once are property working..
