event_route[tm:local-response] only executes a few times
by Kaufman 10 Jul '23

10 Jul '23

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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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(a)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

Random number
by Ali Taher 07 Jul '23

07 Jul '23

Hello, As per Kamailio documentation, $RANDOM returns a random value from the [0 - 2^31) range. But when testing it it's always returning a random number of 9 or 10 digits. I'm not sure if it's always the case or if it can also returns numbers with 1 or 2 digits as well. Another question, how can I force it to return a number of specific digits starting with certain prefix. Regards,

Finding a way to gracefully restart kamailio with dialog module enabled and DMQ sync
by Benoît Panizzon 07 Jul '23

07 Jul '23

Hi Gang We are still having massive issues on how to safely reload kamailio after config changes when using the dialog module and DMQ. If there are active dialogues, kamailio corrupts them on a restart even when using MySQL as dialog backend. As we use two core nodes for redundancy, I am looking for a way to gracefully restart kamailio. I am considering adding some key in a hash table or anything else I can reload on runtime to indicate to kamailio not to accept any new calls (effectively rejecting Invites without To-Tag with 503 causing the registrar or IC peer to hopefully resend the invite to the other node). Then wait, until no more dialogues are active, so kamailio can safely be restarted. My Issue now: How can I find out, one specific node does not have any active dialogues? 'kamcmd dlg.stats_active' returns the count of all DMQ synced nodes, not of the local one. And suggestions or any other ideas how I can 'reload' the kamailio config without disrupting active dialogues? My last resort would be to look into the database: modparam("dialog", "h_id_start", -1) # Use server_id modparam("dialog", "h_id_step", 2) So odd/even H_ID should tell me the number per node. But I see a lot of orphan dialogues hanging around in the database not being cleaned so I guess that will not be reliable at all. Yes, I know I will get the question: 'Why do you need to restart kamailio that often'. We have started production on our kamailio based TSP platform. And of course, despite a LOT of testing beforehand, there is always some issue that pops up. At the moment, I have to implement a config change about once or twice a week to fix some new minor issues. I hope, somewhen in the future we will hopefully have a stable config which will last for several months, but at the moment this is the situation. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Randomize calling number
by Ali Taher 06 Jul '23

06 Jul '23

Hello, What is the best way to change the calling number to a random number (based on specific pattern, like number of digits for example) in an invite packet without using a database. So the scenario is : * receive an invite packet from certain source * change the calling number * send back the invite packet including the new calling number to the original source. Regards, Ali Taher

302 Handling issue in failure route
by Devang Dhandhalya 05 Jul '23

05 Jul '23

Hello All I am handling 302 response in the failure route and when receiving 302 response in kamailio, it's not going into the failure route , kamailio just executing the onreply route when 302 response are received. A few days ago the same code with failure route worked but now it does not. i dont know why kamailio is not executing a failure route from where we can redirect calls to another server. code snippet route[RELAY]{ t_on_reply("MANAGE_REPLY"); t_on_failure("MANAGE_FAILURE"); t_on_branch("MANAGE_BRANCH"); if (!t_relay()) { sl_reply_error(); } exit; } failure_route[MANAGE_FAILURE] { if (t_is_canceled()) { exit; } if (t_check_status("302")){ get_redirects("*"); $ru= $T_rpl($sel(contact.uri)); route(RELAY); } } kamailio version : 5.6.4 Please suggest if I am doing anything wrong. -- Regards, *Devang Dhandhalya* -- *Disclaimer* In addition to generic Disclaimer which you have agreed on our website, any views or opinions presented in this email are solely those of the originator and do not necessarily represent those of the Company or its sister concerns.

SL absorbed ACK is counted as dropped by core.drop_requests
by Kaufman 03 Jul '23

03 Jul '23

Just checking to see if this is the designed behavior. The SL module will attempt to match ACKs for stateless replies and handle them (absorb them?). The question I have is that it looks as though this ACK gets counted as dropped by the core.drop_requests from the KEX module. Tested using this config: #!KAMAILIO loadmodule "pv" loadmodule "sl" loadmodule "xlog" loadmodule "kex" loadmodule "corex" loadmodule "ctl" modparam("sl", "bind_tm", 0) route { xinfo("[$ci] $rm Request. Src:[$si:$sp] RURI:[$ru] To:[$tu] From:[$fu]\n"); sl_send_reply("404", "Not Found"); } event_route[sl:filtered-ack] { xnotice("sl:filtered-ack ACK [$ci] to local reply absorbed\n"); } Then validate by kamcmd stats.fetch core:drop_requests Is this the designed and "correct" behavior?

Forward Registration
by nutxase 28 Jun '23

28 Jun '23

Hi All I have setup kamailio using websockets(wss) i am trying to forward any registration that comes to kamailio to go to asterisk, so in theory kamailio is a registration proxy i have set rewritehostport("xxx.xxx.xxx[:5080](http://node3.sipalto.com:5080)"); the registration forwards fine but the contact on asterisk side shows as sip:xxx:kamailioip.xxxx.invalid so therefore asterisk sees the sip peer as offline what am i missing :( Sent with [Proton Mail](https://proton.me/) secure email.
