Hello, yes, the tm:local-reponse should be executed for every locally generated reply. I could also reproduce this with kamailio-devel. After some time, the log messages appear again. So, it seems like an interesting condition that it only works some of the time. There seems to be also a bug open for that from last year: https://github.com/kamailio/kamailio/issues/3064 5(5634) INFO: <script>: [OPTIONS 1805508309@116.203.XXX.XX-1<mailto:1805508309@116.203.183.57-1>] Src:[127.0.0.1:52784] RURI:[sip:foo@localhost] To:[sip:foo@localhost] From:[sip:sipsak@116.203.XXX.XX:22625<sip:sipsak@116.203.183.57:22625>] 4(5633) INFO: <script>: [OPTIONS 1901775789@116.203.XXX.XX-1<mailto:1901775789@116.203.183.57-1>] Src:[127.0.0.1:39363] RURI:[sip:foo@localhost] To:[sip:foo@localhost] From:[sip:sipsak@116.203.XXX.XX:53534<sip:sipsak@116.203.183.57:53534>] 8(5637) INFO: <script>: [OPTIONS 1849285454@116.203.XXX.XX-1<mailto:1849285454@116.203.183.57-1>] Src:[127.0.0.1:32090] RURI:[sip:foo@localhost] To:[sip:foo@localhost] From:[sip:sipsak@116.203.XXX.XX:9877<sip:sipsak@116.203.183.57:9877>] 29(5658) INFO: <script>: [OPTIONS 1193289168@116.203.XXX.XX-1<mailto:1193289168@116.203.183.57-1>] Src:[135.125.190.71:56243] RURI:[sip:kam01.tst.xxx.xxxxxx.xxx] To:[sip:kam01.tst.xxx.xxxxxx.xxx] From:[sip:sipsak@116.203.XXX.XX:56243<sip:sipsak@116.203.183.57:56243>] 29(5658) CRITICAL: <script>: [OPTIONS 1193289168@116.203.XXX.XX-1<mailto:1193289168@116.203.183.57-1>] tm:local-response replied locally 29(5658) INFO: <script>: [OPTIONS 1193289168@116.203.XXX.XX-2<mailto:1193289168@116.203.183.57-2>] Src:[135.125.190.71:56243] RURI:[sip:kam01.tst.xxx.xxxxxx.xxx] To:[sip:kam01.tst.xxx.xxxxxx.xxx] From:[sip:sipsak@116.203.XXX.XX:56243<sip:sipsak@116.203.183.57:56243>] 29(5658) INFO: <script>: [OPTIONS 1193289168@116.203.XXX.XX-3<mailto:1193289168@116.203.183.57-3>] Src:[135.125.190.71:56243] RURI:[sip:kam01.tst.xxx.xxxxxx.xxx] To:[sip:kam01.tst.xxx.xxxxxx.xxx] From:[sip:sipsak@116.203.XXX.XX:56243<sip:sipsak@116.203.183.57:56243>] 3(5632) INFO: <script>: [OPTIONS 854771556@116.203.XXX.XX-1<mailto:854771556@116.203.183.57-1>] Src:[127.0.0.1:3782] RURI:[sip:foo@localhost] To:[sip:foo@localhost] From:[sip:sipsak@116.203.XXX.XX:31297<sip:sipsak@116.203.183.57:31297>] 2(5631) INFO: <script>: [OPTIONS 1852254840@116.203.XXX.XX-1<mailto:1852254840@116.203.183.57-1>] Src:[127.0.0.1:30019] RURI:[sip:foo@localhost] To:[sip:foo@localhost] From:[sip:sipsak@116.203.XXX.XX:19102<sip:sipsak@116.203.183.57:19102>] 1(5630) INFO: <script>: [OPTIONS 2036725432@116.203.XXX.XX-1<mailto:2036725432@116.203.183.57-1>] Src:[127.0.0.1:19999] RURI:[sip:foo@localhost] To:[sip:foo@localhost] From:[sip:sipsak@116.203.XXX.XX:39149<sip:sipsak@116.203.183.57:39149>] Cheers, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://gilawa.com<https://gilawa.com/> From: Kaufman &lt;bkaufman(a)bcmone.com&gt; Sent: Freitag, 7.

Do not click links or open attachments unless you recognize the sender and know the content is safe. Hello, I'm writing a 302 redirect server and wanting to capture some events on all replies, so I'm trying to do this in event_route[tm:local-response], but I noticed that the event route is only called a few times for the first few requests, and then never gets executed again. This is the simplest case in which I can reproduce the issue: #!KAMAILIO loadmodule "pv" loadmodule "tm" loadmodule "xlog" route { xinfo("[$rm $ci-$cs] Src:[$si:$sp] RURI:[$ru] To:[$tu] From:[$fu]\n"); t_send_reply("404", "Not Found"); exit; } event_route[tm:local-response] { xcrit("[$rm $ci-$cs] tm:local-response replied locally\n"); } If I start Kamailio with kamailio -ddDDeE it has 8 children. If I use sipp to send 10 requests, this is what I see in the kamailio logs. The critical line in the event route is only printed four times. This is tested on 5.7.0 and 5.6.4 9(66) INFO: <script>: [INVITE 1-14@172.26.0.3-1<mailto:1-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 9(66) CRITICAL: <script>: [INVITE 1-14@172.26.0.3-1<mailto:1-14@172.26.0.3-1>] tm:local-response replied locally 10(67) INFO: <script>: [ACK 1-14@172.26.0.3-1<mailto:1-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 11(68) INFO: <script>: [INVITE 2-14@172.26.0.3-1<mailto:2-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 11(68) CRITICAL: <script>: [INVITE 2-14@172.26.0.3-1<mailto:2-14@172.26.0.3-1>] tm:local-response replied locally 12(69) INFO: <script>: [ACK 2-14@172.26.0.3-1<mailto:2-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 13(70) INFO: <script>: [INVITE 3-14@172.26.0.3-1<mailto:3-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 13(70) CRITICAL: <script>: [INVITE 3-14@172.26.0.3-1<mailto:3-14@172.26.0.3-1>] tm:local-response replied locally 14(71) INFO: <script>: [ACK 3-14@172.26.0.3-1<mailto:3-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 15(72) INFO: <script>: [INVITE 4-14@172.26.0.3-1<mailto:4-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 15(72) CRITICAL: <script>: [INVITE 4-14@172.26.0.3-1<mailto:4-14@172.26.0.3-1>] tm:local-response replied locally 16(73) INFO: <script>: [ACK 4-14@172.26.0.3-1<mailto:4-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 9(66) INFO: <script>: [INVITE 5-14@172.26.0.3-1<mailto:5-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 10(67) INFO: <script>: [ACK 5-14@172.26.0.3-1<mailto:5-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 11(68) INFO: <script>: [INVITE 6-14@172.26.0.3-1<mailto:6-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 12(69) INFO: <script>: [ACK 6-14@172.26.0.3-1<mailto:6-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 13(70) INFO: <script>: [INVITE 7-14@172.26.0.3-1<mailto:7-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 14(71) INFO: <script>: [ACK 7-14@172.26.0.3-1<mailto:7-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 15(72) INFO: <script>: [INVITE 8-14@172.26.0.3-1<mailto:8-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 16(73) INFO: <script>: [ACK 8-14@172.26.0.3-1<mailto:8-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 9(66) INFO: <script>: [INVITE 9-14@172.26.0.3-1<mailto:9-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 10(67) INFO: <script>: [ACK 9-14@172.26.0.3-1<mailto:9-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 11(68) INFO: <script>: [INVITE 10-14@172.26.0.3-1<mailto:10-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] 12(69) INFO: <script>: [ACK 10-14@172.26.0.3-1<mailto:10-14@172.26.0.3-1>] Src:[172.26.0.3:5060] RURI:[sip:service@172.26.0.2:5060] To:[sip:service@172.26.0.2:5060] From:[sip:sipp@172.26.0.3:5060] Kaufman
