Hi, I have a strange problem with Kamailio 3.0.2. When one of our end users makes a call Kamailio does not route the ACK (in response to the 200 OK). For all other end users it works fine. For me it looks the the has_totag() checks for some reason fails and then t_check_trans() thinks it is a ACK to a local transactions and then terminates the script. Otherwise there should be more lines in the log file.

The conf is pretty standard. route{ xlog("L_WARN", "New request - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); xlog("L_WARN", "ua=$ua"); if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if(!sanity_check("1511", "7")) { xlog("Malformed SIP message from $si:$sp\n"); exit; } if (has_totag()) { xlog("L_WARN", "has_totag start - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { xlog("L_WARN", "loose_route - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); route(RELAY); } else { if (is_method("SUBSCRIBE")&& uri == myself) { # in-dialog subscribe requests #route(PRESENCE); exit; } if ( is_method("ACK") ) { if ( t_check_trans() ) { xlog("L_WARN", "ACK t_check_trans - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); # non loose-route, but stateful ACK; must be an ACK after a 487 or e.g. 404 from upstream server t_relay(); exit; } else { xlog("Ignoring ACK - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); # ACK without matching transaction ... ignore and discard.\n"); exit; } } sl_send_reply("404","Not here"); } xlog("L_WARN", "has_totag end - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); exit; } #initial requests # CANCEL processing if (is_method("CANCEL")) { if (t_check_trans()) t_relay(); exit; } setflag(4); t_check_trans(); ...

Sorry for the delay, but a had to wait for the customer to make a test call. I placed a xlog("L_WARN", "has_totag after - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); just after the if (has_totag()) { .. } and it does not show in the log. It looks very strange to me.

I thought that it may be the email body formatting so that the second Via header body gets on next line after SIP/2.0/UDP. Can you check your trace, is it on next line (i.e., there is a new line)? If the Via is on two lines like it is presented, then it is invalid. A header body can continue on a new line, but it as to start with whitespace. Regarding sanity, the module drops silently broken messages if you don't set autodrop to 0: http://kamailio.org/docs/modules/stable/modules/sanity.html#autodrop Note that you need latest version of branch 3.1/master for it.
