[Serusers] Ser0.8.14 + Mediaproxy

[Bastian Schern]

For me the Example works only with a small modification. I had modified
the ser.cfg in this way:
--- snip ---
debug=8
fork=yes
log_stderror=yes
check_via=no
dns=no
rev_dns=no
port=5060
children=4

     # initial sanity checks -- messages with
     # max_forwards==0, or excessively long requests
     if (!mf_process_maxfwd_header("10")) {
         sl_send_reply("483","Too Many Hops");
         break;
     };
     if (msg:len >=  max_len ) {
         sl_send_reply("513", "Message too big");
         break;
     };

     # Force subsequent messages to pass trough this proxy
     record_route();

             use_media_proxy();
         };
         # end media session for BYE and CANCEL is done above
         # before entering the loose route. no need to call it here
         t_relay();
         break;
     };

     if (uri==myself) {

         if (method=="REGISTER") {
             # Mark as NAT'ed
             if (client_nat_test("3")) {
                 setflag(2);
                 force_rport();
                 fix_contact();
             };

             if (!www_authorize("universe", "subscriber")) {
                 www_challenge("universe", "0");
                 break;
             } else if (!check_to()) {
                 sl_send_reply("403", "Username!=To not allowed");
                 break;
             };

             if (!save("location")) {
                 sl_reply_error();
             };
         };

#       if (is_uri_host_local()) {
             if (!lookup("location")) {
                 sl_send_reply("404", "Not found");
                 break;
             };
#       };

     } else {
         sl_send_reply("403", "This domain is not served here");
         break;
     };

#   if (method=="INVITE") {
     if (method=="12345") {
         if (!(is_from_local() || is_uri_host_local())) {
             sl_send_reply("403", "Relaying is forbidden");
             break;
         };
         t_on_failure("1");
     } else if (method == "BYE" || method == "CANCEL") {
         end_media_session();
     };

     if (client_nat_test("3") && !search("^Record-Route:")) {
         # Mark as NAT'ed
         force_rport();
         fix_contact();
     };

     if (method=="INVITE") {
         t_on_reply("1");
     };

     if (method=="INVITE" || method=="ACK") {
         use_media_proxy();
     };

     if (!t_relay()) {
         if (method=="INVITE" || method=="ACK") {
             end_media_session();
         };
         sl_reply_error();
     };
}

failure_route[1] {
     end_media_session();
}

onreply_route[1] {
     if (status=~"(183)|(2[0-9][0-9])") {
         if (client_nat_test("1")) {
             fix_contact();
         };
         use_media_proxy();
     };
}

--- snap ---

Bit still I have some problems with some buggy clients they will cause
some endless loops in SER.
Is this about that warning:
12(24531) Warning: sl_send_reply: I won't send a reply for ACK!!

And my phones will not register a hangup.

Is this the reason or my bad config?

Thanks
