Jansson question
by Barry Flanagan 06 Apr '22

06 Apr '22

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

by bayu p 06 Apr '22

06 Apr '22

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 05 Apr '22

05 Apr '22

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 05 Apr '22

05 Apr '22

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 05 Apr '22

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

Asterisk, unable to find dialog for ACK with route param and call-id
by Trevor Peirce 05 Apr '22

05 Apr '22

Hello, I'm having some trouble with what I think is the dialog module. I've got Kamailio 5.5.4 running well for some time. Recently I added Asterisk to the mix and have come across an issue. Call to Kamailio. Kamailio sends it to Asterisk. Asterisk may decide to "forward" the call. To do this it will place a new outbound call through Kamailio. From the user perspective, this works absolutely fine (invite, ringing, ok, bye). The acc module handles it fine also. However dialog does not, and the events for ok and bye do not fire on the original call. They do fire for the forwarded call. I've added some logging output to try to isolate the problem, but I'm no further ahead. Here's what I have. Any suggestions? ** Call initiated ** INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=100 ru=<null> tu=sip:destination@endpoint DLG_status=<null> dlg-h-id=3360 INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=100 ru=<null> tu=sip:fwddest@0.0.0.1:5060 DLG_status=<null> dlg-h-id=12036 INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=183 ru=<null> tu=sip:fwddest@0.0.0.1:5060 DLG_status=<null> dlg-h-id=12036 INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=183 ru=<null> tu=sip:destination@endpoint DLG_status=<null> dlg-h-id=3360 INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=200 ru=<null> tu=sip:fwddest@0.0.0.1:5060 DLG_status=<null> dlg-h-id=12036 CRITICAL: dialog [dlg_timer.c:200]: update_dlg_timer(): Trying to update a bogus dlg tl=0x7fa0494006e8 tl->next=(nil) tl->prev=(nil) ERROR: dialog [dlg_hash.c:1329]: update_dlg_timeout(): failed to update dialog lifetime CRITICAL: dialog [dlg_timer.c:200]: update_dlg_timer(): Trying to update a bogus dlg tl=0x7fa0494006e8 tl->next=(nil) tl->prev=(nil) ERROR: dialog [dlg_hash.c:1329]: update_dlg_timeout(): failed to update dialog lifetime ERROR: dialog [dlg_profile.c:1028]: dlg_set_timeout_by_profile(): Unable to set timeout on 3306:12036 NOTICE: acc [acc.c:270]: acc_log_request(): ACC: transaction answered: timestamp=1648611824;time_unix=1648611824.346;method=INVITE;from_tag=as292200a1;to_tag=as75834dc4;call_id=7cef233547dca0ac7882ce5249b3b54c;code=200;reason=OK INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=200 ru=<null> tu=sip:destination@endpoint DLG_status=<null> dlg-h-id=<null> NOTICE: acc [acc.c:270]: acc_log_request(): ACC: transaction answered: timestamp=1648611824;time_unix=1648611824.354;method=INVITE;from_tag=as730369e7;to_tag=as3b06b3e2;call_id=53bad4f0034b61a5745163d82daef402;code=200;reason=OK INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=200 ru=<null> tu=sip:destination@endpoint DLG_status=<null> dlg-h-id=<null> WARNING: dialog [dlg_handlers.c:1328]: dlg_onroute(): unable to find dialog for ACK with route param '161.02d' [353:3360] and call-id '53bad4f0034b61a5745163d82daef402' WARNING: dialog [dlg_handlers.c:1328]: dlg_onroute(): unable to find dialog for ACK with route param '161.02d' [353:3360] and call-id '53bad4f0034b61a5745163d82daef402' ** The call is answered and endpoints can talk to each other ** ** Now the original caller hangs up ** WARNING: dialog [dlg_handlers.c:1328]: dlg_onroute(): unable to find dialog for BYE with route param '161.02d' [353:3360] and call-id '53bad4f0034b61a5745163d82daef402' NOTICE: acc [acc.c:270]: acc_log_request(): ACC: transaction answered: timestamp=1648611831;time_unix=1648611831.933;method=BYE;from_tag=as730369e7;to_tag=as3b06b3e2;call_id=53bad4f0034b61a5745163d82daef402;code=200;reason=OK INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=100 ru=<null> tu=sip:fwddest@0.0.0.1:5060 DLG_status=<null> dlg-h-id=12036 INFO: <script>: onreply_route[MANAGE_REPLY] branch [0] rm=INVITE rs=200 ru=<null> tu=sip:fwddest@0.0.0.1:5060 DLG_status=<null> dlg-h-id=12036 ERROR: <script>: got result for bye = Bye!; DLG_lifetime = 8 NOTICE: acc [acc.c:270]: acc_log_request(): ACC: transaction answered: timestamp=1648611832;time_unix=1648611832.115;method=BYE;from_tag=as292200a1;to_tag=as75834dc4;call_id=7cef233547dca0ac7882ce5249b3b54c;code=200;reason=OK ERROR: dialog [dlg_handlers.c:363]: dlg_terminated_confirmed(): failed to get dialog from params! ** Everything ends cleanly on the other SIP endpoints ** What can I do from here to try to isolate this further?

Kamailio PCSCF route logic
by Weiqi Yao 30 Mar '22

30 Mar '22

Hello community, We made some modifications to Kamailio PCSCF sample cfg file, so when PCSCF receiving an tcp SUBSCRIBE message it add ;transport=tcp to the end of Contact URI. Below is what we added the route block right after if (is_method("INVITE|SUBSCRIBE")) logic if (is_method("SUBSCRIBE") && proto=='tcp') { $var(original_contact_header) = $ct; $var(new_contact_header) = $(var(original_contact_header){re.subst,/(.*:.*)(>);/\1;transport=tcp>/g}); remove_hf("Contact"); append_hf("Contact: $var(new_contact_header)\r\n"); msg_apply_changes(); } We did see the ;transport=tcp been added but we also seeing a bad line ;alias=[...] is added before the To: line [cid:image001.png@01D84375.8D109B20] Does anyone know what function might cause this ;alias been added before To: line? BR, Weiqi

More than TCP 800 concurrent calls, slows Kamailio (LUA FILE API REQUESTS)
by Giovanni Jose 30 Mar '22

30 Mar '22

Hello Guys I am having this issue where kamailio is receiving requests from SIPp (we are currently testing the platform and doing QA) but if we do more than 800 concurrent calls kamailio starts failing and slowing the requests, The scenario is the following: I am sending 5000 calls at 100 CPS on TCP and I am having this route in the configuration file: # Handle the calls to api route[CALL_API] { xlog("L_NOTICE"," Call request $var(call_request) method: $rm \n"); $var(loop_true)=1; while ($var(loop_true)) { if(!lua_run("call_request","$var(call_request)","$sht(token=>new_token)")) { xlog("L_NOTICE", "SCRIPT: failed to execute lua function!\n"); } if ($var(loop_true)){ sleep("1"); } } xlog("L_NOTICE", "SCRIPT: Sucess to execute lua function!\n"); } So I am executing a LUA script for the requests and the API response will tell the destination of the 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

dispatcher socket attrs binding
by David Villasmil 29 Mar '22

29 Mar '22

Hello guys, Im starting kamailio with listen=0.0.0.0:5060 and in my dispatcher list i have in the attrs something like: socket=udp:172.17.0.2:5060 That IP address belongs to kamailio's host and it is binging to it. Is it right i can't set a specific IP in the socket attribute if listen is 0.0.0.0? maybe i should be able to? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

nathelper OPTIONS ping
by Xuo Guoto 28 Mar '22

28 Mar '22

Hello all, I am trying to periodically send SIP OPTIONS to all connected WebRTC clients from Kamailio. The functionality is similar to qualify=yes of Asterisk. Following are the configuration changes I have made to get this working. #!define FLB_NATSIPPING 7 <snip/> loadmodule "nathelper.so" <snip/> # ----- nathelper params ----- modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "natping_interval", 20) modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org") <snip/> # Handle SIP registrations route[REGISTRAR] { if (is_method("REGISTER")) { xlog("L_INFO", "Processing REGISTER in route[REGISTRAR]\n"); if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); # do SIP NAT pinging xlog("L_INFO", "Setting FLB_NATSIPPING\n"); setbflag(FLB_NATSIPPING); } if (!save("location")) { sl_reply_error(); } xlog("L_INFO", "Successfully processed REGISTER in route[REGISTRAR]\n"); exit; } } When the WebRTC client registers, I can see the log: Setting FLB_NATSIPPING, but SIP OPTIONS packets are not seen. I am checking it using the Chrome console, at client side as well as sipdump module in server side. Do I have to do any additional configuration? I am not posting the full config file here so that its easy to focus on the relevant parts, but can do that if needed. Thanks and regards, X.

t_suspend / t_continue & insert_hf
by Fuad Trle 28 Mar '22

28 Mar '22

Hello, I'm inserting some headers after getting value from http_async_query. If a call is relayed, I see them. But If I t_suspend and t_continue call (before time out), I do not see added headers. Here is flow: route(START) t_newtran(); #.. prep for query http_async_query("url","HTTP"); route(HTTP) #.. collect and using data from query insert_hf("$var(key): $var(value)\r\n"); t_store(); if (registered("location") { route(RELAY); } else { t_suspend(); exit; } route(AWAKE) t_continue(); I see that the branch index ($T_branch_idx) is 0 at start. 1 after http query, +1 if there is forking or location. +1 after t_suspend. It looks like t_continue uses a branch with index after t_suspend. I tried with t_save_lumps() to carry over changes. Any idea how to do this?

Using DNS log in
by Steve 26 Mar '22

26 Mar '22

Hello, I have a very basic Kamailio 5.4 configuration on Debian 11 with RTPProxy 2.2 behind a firewall. It works fine with the sip client logging into the server public ip address. However, the sip client is not able to log in when using a dns domain name directed to that public ip address. Is there a specific setting in the Kamailio and/or RTPProxy config files for using a dns domain name instead of a numeric ip address? Also, is there a Kamailio module that allows use of encrypted keys instead of passwords when logging in? Thanks for any info, Steve
