That sample does all the things you don't want to implement.

Your required config is a simple proxy.
https://kamailio.org/docs/modules/stable/modules/dispatcher.html#dispatcher.ex.config
contains a config example, which sends all traffic to 1 dispatcher. You need to modify this a little. Add a second dispatcher so you have 1 for your upstream and 1 for your freeswitch. If a message arrives from 1 dispatcher send it to the other. For example something like:

route[DISPATCH]
{
  if(ds_is_from_list("1"))
  {
    ds_select_dst("2", "4");
  }
  else if(ds_is_from_list("2"))
  {
    ds_select_dst("1", "4");
  }
  else
  {
    sl_send_reply("403","Forbidden");
	exit;
  }
...
