Dear experts, Would appreciate if anyone can explain why in the given sample Lua script the 'Handle Retransmission' block checks the return code of t_check_trans (if KSR.tm.t_check_trans == 0 then), but in the Kamailio native config standard file if just calls the t_check_trans() function without checking the return code. What is the intention here and how does it work? Thank you in advance. Handle retransmission script from native config file: if (!is_method("ACK")) { if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); } Handle retransmission from sample Lua script: if not KSR.is_ACK() then if KSR.tmx.t_precheck_trans() > 0 then KSR.tm.t_check_trans(); return 1; end if KSR.tm.t_check_trans() == 0 then return 1; end end

secsipid and secsipid_proc module RPM build

by Володимир Іванець

Hello! I was wondering if someone was trying to build Kamailio RPM packages containing modules secsipid and secsipid_proc and faced the same problem. I compiled secsipidx library and copied secsipid.h, libsecsipid.h as well as libsecsipid.a files into the source directory of secsipid_proc module. And when I'm trying to build RPM packages, I get the following error: CC (gcc) [M secsipid_proc.so] secsipid_proc_mod.o secsipid_proc_mod.c:28:10: fatal error: secsipid.h: No such file or directory #include <secsipid.h> ^~~~~~~~~~~~ compilation terminated. make[2]: *** [../../Makefile.rules:100: secsipid_proc_mod.o] Error 1 make[1]: *** [Makefile:508: modules] Error 1 make[1]: Leaving directory '/builddir/build/BUILD/kamailio-5.8.2/src' make: *** [Makefile:34: every-module] Error 2 Thanks a lot!

Permissions module - automatic reload

by Sergio Charrua

Hi all, Just need some clarifications about the Permissions module: I currently use it with db_mode = 1 and was expecting that the parameter "trusted_cleanup_interval" would refresh the cache tables every X seconds, but apparently this is not the case. I was looking for a way for Kamailio to automatically reload the address table into memory every 5 minutes, for example, and I (mis)understood that "trusted_cleanup_interval" would do the trick, but it doesn't work as expected. Question: is there any command, besides kamcmd, to automatically reload the permissions table? I would like to avoid having to add a line in the crontab.... Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

Using a different OpenSSL

by David Cunningham

Hello, We have compiled openssl 3.0.9 from source because it's FIPS validated, and want to use it with Kamailio. The server also has the Ubuntu openssl 3.0.2 package installed. Does anyone know how we can tell Kamailio to use the openssl library in /opt/openssl/lib64, and how we can verify that it really is using it? Thanking you in advance, -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782

How to restrict Kamailio adding Local VIA header

by panda.paresh＠gmail.com

Hi All, I am trying to replay a request to the destination via Kamailio, and I am using t_relay_to_tcp for that , but in that case Kamailio is adding its own address as the top VIA header. Is there a way I can instruct Kamailio not to add local via header ?

http_async and tm

by alexis

Hello all, context first, we have an REST API that performs queries to external devices in the network (diameter to DRA's, REST to different servers) and based on n conditions returns the content for a Contact header to be used in a SIP 302. Now we're consuming this API with http_client (synchronously) and as there's no way to speed up the API (pipeline executions, delays on external api's etc etc) we're hitting a limit where all children become busy waiting for the API to answer. So i decided to move to http_async_client and started working on it on the lab with this first and base concept to test. request_route { #for testing purposes only if(is_method("ACK")){ exit; } $http_req(all) = $null; $http_req(suspend) = 1; $http_req(timeout) = 500; $http_req(method) = "POST"; $http_req(hdr) = "Content-Type: application/json"; jansson_set("string", "event", "sip-routing", "$var(cre_query)"); xlog("L_INFO","API ASYNC ROUTING REQUEST: $var(cre_query)\n"); $http_req(body) = $var(cre_query); t_newtran(); http_async_query("http://192.168.86.128:8000/", "CRE_RESPONSE"); } http://192.168.86.128:8000/ receives the POST, randomly creates a delay between 0.5 and 1 second and responds (simulating the real api with an excess delay to probe the concept) Then route[CRE_RESPONSE] { if ($http_ok && $http_rs == 200) { xlog("L_INFO","CRE RESPONSE: $http_rb\n"); # for testing purpose, Contact content will be replaced from the received api response append_to_reply("Contact: <sip:1234@google.com>\r\n"); send_reply(302,"Moved Temporarily"); exit; } send_reply(500, "Internal error"); exit; } INVITE is received and processed, API is called, after API response, 302 is replied and then an ACK (ignored by now). Situation is that the 302 retransmitted 37 1519.846253067 192.168.86.34 → 192.168.86.128 SIP/SDP 585 Request: INVITE sip:service@192.168.86.128:5060 | 38 1519.848100380 192.168.86.128 → 192.168.86.34 SIP 318 Status: 100 Trying | 39 1520.094997642 192.168.86.128 → 192.168.86.34 SIP 407 Status: 302 Moved Temporarily | 40 1520.102323728 192.168.86.34 → 192.168.86.128 SIP 453 Request: ACK sip:service@192.168.86.128:5060 | 41 1520.591300933 192.168.86.128 → 192.168.86.34 SIP 407 Status: 302 Moved Temporarily | 42 1521.591061065 192.168.86.128 → 192.168.86.34 SIP 407 Status: 302 Moved Temporarily | 43 1523.591227956 192.168.86.128 → 192.168.86.34 SIP 407 Status: 302 Moved Temporarily | 18(24) DEBUG: tm [t_reply.c:1703]: t_retransmit_reply(): reply retransmitted. buf=0x7f6d79745dc0: SIP/2.0 3..., shmem=0x7f6d75187fd8: SIP/2.0 3 18(24) DEBUG: tm [t_reply.c:1703]: t_retransmit_reply(): reply retransmitted. buf=0x7f6d79745dc0: SIP/2.0 3..., shmem=0x7f6d75187fd8: SIP/2.0 3 18(24) DEBUG: tm [t_reply.c:1703]: t_retransmit_reply(): reply retransmitted. buf=0x7f6d79745dc0: SIP/2.0 3..., shmem=0x7f6d75187fd8: SIP/2.0 3 18(24) DEBUG: tm [timer.c:634]: wait_handler(): finished transaction: 0x7f6d75184cc8 (p:0x7f6d74f600c8/n:0x7f6d74f600c8) 18(24) DEBUG: tm [h_table.c:132]: free_cell_helper(): freeing transaction 0x7f6d75184cc8 from timer.c:643 Any help to avoid the retransmission and make the transaction just finish right after the 302 will be appreciated. regards
