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 {

This is part of my openser.cfg

^^^^^^^^ - you haven't sent route[9], check it to see if you drop the ACKs in there (you should treat them almost the same as the invites)break; } else if (method=="CANCEL") { route(5); break; } else if (method=="INVITE") { setflag(1); route(5); break;[...]
I dont think that my UA is broken, same results have all my ipphones and softphones :(
The ACK was not dropped because the UA was broken, but nevertheless you the UA didn't properly handle record-routing.
