I've installed 2 Freeswitch on different servers and would like to have Kamailio load balance between them.

I've installed Kamailio following:
http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-3.1.x-from-git

I've created dispatcher.list and added:
loadmodule "dispatcher.so"

modparam("dispatcher", "list_file", "../etc/dispatcher.list")
in the kamailio.cfg.

But looking at:
http://kamailio.org/docs/modules/3.1.x/modules_k/dispatcher.html
I'm having difficulties to placing:
ds_select_dst("1", "0"); 
in the kamailio.cfg that was created originally.

Can anyone help me?
