I agree. This is the next for me. I kind of hope to use freeswitch for that too.

I guess you're registering in Kamailio but your "TOASTERISK" and
"FROMASTERISK" routes relay the entire session directly to the
asterisk server that was selected without touching it. I must look in
this.

Regarding the "easy" solution you proposed, if I understand correctly,
I need to implement a single route function with a simple dipatcher,
like the example in the dipatcher module:

route{
  if ( !mf_process_maxfwd_header("10") )
    {
      sl_send_reply("483","To Many Hops");
      drop();
    };

  ds_select_dst("2", "0");

  forward();
  # t_relay();
}

How do I modify that example to recognize that a request is coming
from the same "user" ?
