Thank you for your reply!
But i'm still misundestand what to do, sorry i'm a beginner :(
if (uri==myself) {
append_hf("P-hint: Local Destination\r\n");
if (method=="ACK") {
setflag(1);
route(9);
break;
..........
route[9] {
if (method=="ACK") {
t_relay();
return;
};
lookup("aliases");
if (uri!=myself) {
route(1);
break;
};
lookup("location");
route(1);
}
is it right ???
in syslog i see LOOP DETECTED and warning: sl_send_reply:i won't send a reply for ack
the whole route block
route {
