Hello,

what you can do is to route the messages to the other proxy if there is 
no contacts in the local location table, something like:

if(!lookup("location") {
     if(src_ip==_THE_OTHER_KAMAILIO_IP_) {
         send_reply("404", "Not found");
         exit;
     }
     $du = "sip:_THE_OTHER_KAMAILIO_IP_");
     t_relay();
     exit;
}

Cheers,
Daniel
