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

Your required config is a simple proxy.
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:

    ds_select_dst("2", "4");
  else if(ds_is_from_list("2"))
    ds_select_dst("1", "4");
