least cost routing module activation error

by bayu p

Dear Kamailio Expert, I already add module lcr, but found error when searching pvar "ddn" inside source code core/pvapi.c at line 923, as shown error log captured below : Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/pvapi.c:923]: pv_parse_spec2(): error searching pvar "ddn" Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/pvapi.c:1126]: pv_parse_spec2(): wrong char [n/110] in [$ddn] at [3 (0)] Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: xlog [xlog.c:511]: xdbg_fixup_helper(): wrong format[Domain of destination: $ddn] Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:901 Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:903 Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:918 The question are, how to define correct "INVITE" methode (or correct format) inside route[LCR] which is already defined inside kamailio.cfg: route[LCR] { if (status=="200") { xlog("LCR: Inside the LCR routen"); } if(method=="INVITE") { xlog("We got an invite"); if(!load_gws(1, $rU, $var(caller_uri))) { xlog("Couldn't load gateways"); sl_send_reply("500", "Server Internal Error - Cannot load gateways"); exit; } else { xlog("GW Selected '$avp(i:709)'n"); xlog("Domain of destination: $ddn"); xlog("To URI: $tun"); } if(!next_gw()) { xlog("Couldn't proceed to next gateway"); sl_send_reply("503", "Service not available, no gateways found"); exit; } else { xlog("Calling the first matched gatewayn"); xlog("ruri_user_avp: '$avp(i:500)'n"); xlog("To URI after next_gw: $tun"); xlog("Request URI: $rUn"); } } } Kind Regards

Jansson question

by Barry Flanagan

Hi I am trying to use the jannson_get function to pull field "secret" from the below json: {"3":{"options":{"secret":"mybigsecret"}}} This works is I use jansson_get("3.options.secret"..... However, I need to know the value of "3" in order to use it. I have tried all the variations on path I can find, but none apart from using the actual root value work for me. How can I either: 1. Construct a PATH which will pick this up, or 2. Obtain this root value ("3" in my example) I have tried testing using https://jsonpath.com/ and a path of "$..secret" and "$..options.secret" works there, but not in jansson kamailio module. Any assistance much appreciated. Thanks -- -Barry

Manual usage and example kamailio kamctl

by bayu p

Dear Expert Kamailio, I use this tutorial kamctl to make kamailio and other sip server communicated https://manpages.ubuntu.com/manpages/xenial/man8/kamctl.8.html but, i cannot found further tutorial how use kamctl. Could you please share, the detail/further tutorial and example of kamctl usage.. Since i always found error/failure during execute some command from the link, here captured: (1). # kamctl cr dump -e \E[37;31mERROR: Error opening Kamailio's FIFO /var/run/kamailio/kamailio_rpc.fifo -e \E[37;31mERROR: Make sure you have loaded the jsonrpcs module and set FIFO transport parameters (2). # kamctl lcr show_gws -e \E[37;31mERROR: command disabled (3). # kamctl lcr reload -e \E[37;31mERROR: command disabled (4). # kamctl ping 192.168.31.50 { "jsonrpc": "2.0", "error": { "code": 400, "message": "Invalid request uri \"192.168.31.50\"" }, "id": 76608 } (5). # kamctl cr reload { "jsonrpc": "2.0", "error": { "code": 500, "message": "Method Not Found" }, "id": 76659 } Warm Regards, >

Kamailio stop processing SIP in high call load with dlg replication via DMQ

by José Seabra

Hi there, I've two kamailio servers sharing dlg vars between them and I've noticed that during high call load (~50-70 CPS) the kamailio that is processing all the calls and sharing the dialogs with the other kamailio, stops processing SIP. If I set the parameter enable_dmq to 0 I cannot replicate the issue so I assume that it's related to dialog replication through DMQ. *Kamailio version: *5.4.7 - I've tested with recent versions but the issue remains *Configurations of Kamailio_1:* # ----- dialog params ----- modparam("dialog", "dlg_flag", FLD_DLG) modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "enable_dmq", 1) modparam("dialog", "h_id_start", 1000) modparam("dialog", "h_id_step", 6000) # ----- dmq params ----- modparam("dmq", "server_address", "sip:INTERNAL_INSTANCE_IP:5060") modparam("dmq", "notification_address", "DMQ_NOTIFICATION_ADDRESS") modparam("dmq", "multi_notify", 1) modparam("dmq", "ping_interval", 10) modparam("dmq", "num_workers",4) *Configurations of Kamailio_2:* # ----- dialog params ----- modparam("dialog", "dlg_flag", FLD_DLG) modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "enable_dmq", 1) modparam("dialog", "h_id_start", 5000) modparam("dialog", "h_id_step", 6000) # ----- dmq params ----- modparam("dmq", "server_address", "sip:INTERNAL_INSTANCE_IP:5060") modparam("dmq", "notification_address", "DMQ_NOTIFICATION_ADDRESS") modparam("dmq", "multi_notify", 1) modparam("dmq", "ping_interval", 10) modparam("dmq", "num_workers",4) In this link you can find the kamctl trap <https://textbin.net/quykw71nyl>output after kamailio stop processing SIP. Thank you Best Regards -- Cumprimentos José Seabra

Auth_ephemeral Module > username_format not accepted

by Luciano Motti

Hi! I was able to successfully use the auth_ephemeral module on my environment: Kamailio > Asterisk > ARI I ran into a problem with ARI, where Asterisk wouldn't send the complete from URI to ARI program, just the first part (timestamp), and the most important part (the username) isn't forwarded. For example: Kamailio username: 1649106119:1001 Asterisk only forwards 1649106119 to ARI, which makes it impossible for me to track the user. So I planned on using the deprecated username_format from Auth Ephemeral module: https://kamailio.org/docs/modules/4.1.x/modules/auth_ephemeral.html#auth_ep… By switching the timestamp with the username, my problems would be fixed. After setting the variable, and trying to register on Kamailio with username 1001:1649106119, I get an error message: SIP/2.0 400 Bad From URI Am I doing something wrong? Thanks!

Re: [SR-Users] More than TCP 800 concurrent calls, slows Kamailio (LUA FILE API REQUESTS)

by Henning Westerholt

Hello, please keep the list in CC, that others can comment as well. Beside from the obvious (improving the performance of the lua API call), you could use indeed asynchronous processing. If you just use the lua code to emit the REST request, using a native http client module would be probably also faster as doing it over lua.

I am noticing that for high volume calls kamailio slows the traffic and shows errors because there's a delay that is been added when the backend responds for every call.

At 800 concurrent calls, I can notice SLOWLINESS in the SIPp testing tool, and then I will start receiving 408 timeouts. This sounds like a load issue or something because I believe there's a time that it's been added every time we hit the backend and wait for the response. any help will be appreciated Regards Gio
