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

Kamailio SCSCF forward SIP INVITE over TCP
by Weiqi Yao 24 Mar '22

24 Mar '22

Hello community, We currently have some issues with Kamailio SCSCF forwarding a large SIP UDP INVITE packet(size around 3000bytes), it got dropped somewhere in the ethernet. I tried increase the MTU size on both sides' interface and even define it on the switch port, but still no luck. So I am thinking to force SCSCF to send this INVITE over TCP, I followed this link: https://andersbrownworth.com/cms/264/, enabled naptr in SCSCF config and configured NAPTR and SRV DNS record, but the SCSCF still stop even forward it out. I think I did the DNS part right cause when I switch the NAPTR record to point to UDP it worked. Anyone have some experience with configure SCSCF forwarding SIP through TCP? BR, Weiqi

I think that there is a bug in the tm module with respect to the "tm:local-response" event route. In the "t_reply.c" file, there is a static variable called '_tm_local_response_set_lookup'. This variable is initialized at load time to zero. It is checked in the '_reply_light()' routine and will initiate a local callback from the config script if "armed". The problem as I see it is that if the callback is readied, the variable is set to one. But it is never reset. So the practical outworking is as follows. A register is received and the request_route arms the callback. The register requires an authorization (local database sqlite). After the 401 is sent back, the callback via the module event route is called as expected. All good except that the module event route script fragment is never executed again after the first call. I'm no expert on the tm module but I would think that somewhere in there, the variable should be reset to zero so that subsequent transactions can initiate the event route again. thanks for any help, Dan -------------- next part -------------- An HTML attachment was scrubbed...

TOPOH is generating new Call-ID for BYE
by Marrold 24 Mar '22

24 Mar '22

Hi, I have enabled the TOPOH module with mask_callid enabled, but it's generating a new Call-ID for a BYE which gets rejected with a 481 downstream. If I disable the TOPOH module it works as expected. Does anyone know where I should start looking? SIP-wise the initial BYE seems compliant. This is Kamailio 5.5.3 on Debian 11 Thanks Matthew

bug in tm module?
by Daniel Paape 23 Mar '22

23 Mar '22

Hello I'm running K5.5.3 and have checked the 'issues' link in github and saw nothing regarding what I am seeing. I think that there is a bug in the tm module with respect to the "tm:local-response" event route. In the "t_reply.c" file, there is a static variable called '_tm_local_response_set_lookup'. This variable is initialized at load time to zero. It is checked in the '_reply_light()' routine and will initiate a local callback from the config script if "armed". The problem as I see it is that if the callback is readied, the variable is set to one. But it is never reset. So the practical outworking is as follows. A register is received and the request_route arms the callback. The register requires an authorization (local database sqlite). After the 401 is sent back, the callback via the module event route is called as expected. All good except that the module event route script fragment is never executed again after the first call. I'm no expert on the tm module but I would think that somewhere in there, the variable should be reset to zero so that subsequent transactions can initiate the event route again. thanks for any help, Dan

SIPS Errors on Kamailio
by Christopher Vincent 23 Mar '22

Hi, Kamailio / RTPEngine was set up on CentOS 8 running SIP to SIPS and RTP to SDES SRTP conversion. This worked as expected Attempted to duplicate the setup on RHEL but errors were seen.

bug in tm module?
by dpaape＠frontier.com 22 Mar '22

22 Mar '22

Hello, I'm running K5.5.3 and have checked the 'issues' link in github and saw nothing regarding what I am seeing. I think that there is a bug in the tm module with respect to the "tm:local-response" event route. In the "t_reply.c" file, there is a static variable called '_tm_local_response_set_lookup'. This variable is initialized at load time to zero. It is checked in the '_reply_light()' routine and will initiate a local callback from the config script if "armed". The problem as I see it is that if the callback is readied, the variable is set to one. But it is never reset.So the practical outworking is as follows. A register is received and the request_route arms the callback. The register requires and authorization. After the 401 is sent back, the callback via the module event route is called. All good except that the module event route script fragment is never executed again after the first call.I'm no expert on the tm module but I would think that somewhere in there, the variable should be reset to zero so that subsequent transactions can initiate the event route. thanks for any help,Dan

SERIAL FORKING : call to a group number
by Youssef Boujraf 22 Mar '22

22 Mar '22

Dear all, My use case is : I defined a username = 112 (for emergency call) This username doesn't exist in subscribers table and unavailable in location table. The idea is when Sopftphone1 call the group = 112 then Kamailio will forward the call to a group using SERIAL FORKING. => Softphone 1 -> Sends INVITE to 112 -> Kamailio -> FORWARD TO SERIAL FORKING (4x softphone all registered and in location table). The q priority could be hybrid that means 2x softphone could have same priority. My issues : - the q priority forced for each softphone is not taking into account. - the first branch created when send INVITE to 112 is still available. My setup Kamailio is behind a NAT.

$ru vs. $fu as r/w pseudo variables

If I set $ru in config file and then print $ru to log, the new value is printed. If I do the same with $fu, the old value is printed. I haven't found in Pseudo-Variables Wiki any documentation about this. Does it exist somewhere else? -- Juha

Dear, When using : sudo kamctl address reload sipsecure@kamailio:/$ sudo kamctl address reload [sudo] password for sipsecure: { "jsonrpc": "2.0", "result": "Reload OK", "id": 73482 } I looked for the command I could use in kamailio.cfg route[JSON_ADDRESS_RELOAD]{ xlog("MY_SEVERITY"," RPC REQUEST : RELOAD ADDRESS TABLE"); jsonrpc_exec('{"jsonrpc": "2.0","method": "permissions.addressReload"}'); exit; } Now I am able to call a rpc command from the code ;-) Best Regards -- Youssef

Periodic keepalive for WebRTC clients
by Xuo Guoto 22 Mar '22

22 Mar '22

Hello all, I have a [SIP client] <-> Kamailio <-> Asterisk installation. Sip clients are both WebRTC and Android app. WebRTC connects via 443 while Android app connects VIA TLS at port 5061. WebRTC client uses jsSIP library. My Kamailio version is 5.5.3 (x86_64/linux) I had been using asterisk directly to terminate WebRTC clients previously and was using the qualify feature to periodically send OPTIONS packet to all connected clients as a keep alive mechanism. This allowed the client to detect any loss of connectivity and reconnect back to server if there is any loss of connectivity. After moving to Kamailio I am looking for a similar feature, where Kamailio sends OPTIONS (or any other packets) periodically to the WebRTC clients. My attempts so far hasn't been a success. I am aware of couple of options for keepliave in kamailio: 1. nat_keeplaive() I have some what naively copied the example from nat_keepalive() documentation into route[NATDETECT] but that is not working. route[NATDETECT] { force_rport(); #!ifdef WITH_WEBSOCKETS if (nat_uac_test(64)) { if (is_method("REGISTER")) { fix_nated_register(); } else { if (!add_contact_alias()) { sl_send_reply("400", "Bad Request"); exit; } } setflag(FLT_NATS); return; } #!endif if (nat_uac_test(19)) { if (is_method("REGISTER")) { fix_nated_register(); } fix_contact(); } setflag(FLT_NATS); if ((method=="REGISTER" || method=="SUBSCRIBE" || (method=="INVITE" && !has_totag())) && client_nat_test("3")) { nat_keepalive(); } return; } 2. keepalive module This looks like what I want, but I am not sure how to add a new WebRTC connection to the list of endpoints for pinging. This is the handler for xhttp:request, should the ka_add_destination be added here? event_route[xhttp:request] { set_reply_close(); set_reply_no_connect(); if ($Rp != MY_WS_PORT #!ifdef WITH_TLS && $Rp != MY_WSS_PORT #!endif ) { xlog("L_WARN", "HTTP request received on $Rp\n"); xhttp_reply("403", "Forbidden", "", ""); exit; } if ($hdr(Upgrade)=~"websocket" && $hdr(Connection)=~"Upgrade" && $rm=~"GET") { if ($hdr(Host) == $null || !is_myself("sip:" + $hdr(Host))) { xhttp_reply("403", "Forbidden", "", ""); exit; } if (ws_handle_handshake()) { exit; } } xhttp_reply("404", "Not Found", "", ""); } My search so far has not returned any other means to send options packets to WebRTC clients. Been banging my head around this for couple of days, and any help will be much appreciated. X.

Dialog module errors with dmq
by Olli Attila 22 Mar '22

22 Mar '22

Hello, I have two Kamailio nodes. Couple of days of ago I enabled dmq to replicate dialogs between these two Kamailio nodes. Now that the dmq is enabled, we are seeing lot of warning and notice messages on kamailio logs related to the dialog module. Is there something I have missed when configuring dlg_manage & dmq replication that might cause this? No calls have been affected negatively by this though. Kamailio 1 node prints lot of this: Mar 4 08:20:25 /usr/sbin/kamailio[14316]: WARNING: dialog [dlg_handlers.c:1328]: dlg_onroute(): unable to find dialog for ACK with route param 'a5d.ebf1' [3418:8126] and call-id 'SDiu98001-dd9c12fea650b9d1408dd672a2c51c9f-v300g00020' Mar 4 08:20:28 /usr/sbin/kamailio[14313]: WARNING: dialog [dlg_handlers.c:1328]: dlg_onroute(): unable to find dialog for BYE with route param 'a5d.ebf1' [3418:8126] and call-id 'SDiu98001-dd9c12fea650b9d1408dd672a2c51c9f-v300g00020' Mar 4 08:21:56 /usr/sbin/kamailio[14315]: WARNING: dialog [dlg_handlers.c:1328]: dlg_onroute(): unable to find dialog for ACK with route param '689.f2f1' [2438:7983] and call-id 'SD8o63c01-47972a87ee1fd8791ddf27b650badcba-v300g00010' Kamailio 2 node prints lot of this: Mar 4 08:20:29 /usr/sbin/kamailio[8005]: NOTICE: dialog [dlg_hash.c:242]: dlg_clean_run(): dialog in early state is too old (0x7fe07b84e980 ref 1) Mar 4 08:20:29 /usr/sbin/kamailio[8005]: NOTICE: dialog [dlg_hash.c:242]: dlg_clean_run(): dialog in early state is too old (0x7fe07bb03360 ref 1) Mar 4 08:21:59 /usr/sbin/kamailio[8005]: NOTICE: dialog [dlg_hash.c:242]: dlg_clean_run(): dialog in early state is too old (0x7fe07b528300 ref 1) (Version: kamailio 5.5.3 (x86_64/linux) 473cef on both kamailio nodes) [root@kamailio-1]# kamcmd dmq.list_nodes { host: 172.19.194.140 port: 5060 proto: * resolved_ip: 172.19.194.140 status: active last_notification: 0 local: 0 } { host: 172.19.194.132 port: 5060 proto: * resolved_ip: 172.19.194.132 status: active last_notification: 0 local: 1 } [root@kamailio-2]# kamcmd dmq.list_nodes { host: 172.19.194.132 port: 5060 proto: * resolved_ip: 172.19.194.132 status: active last_notification: 0 local: 0 } { host: 172.19.194.140 port: 5060 proto: * resolved_ip: 172.19.194.140 status: active last_notification: 0 local: 1 } ### On Kamailio 1: ### #!define DMQ_LOCAL_ADDR "sip:172.19.194.132:5060" #!define DMQ_PEER_ADDR "sip:172.19.194.140:5060" ### On Kamailio 2: ### #!define DMQ_LOCAL_ADDR "sip:172.19.194.140:5060" #!define DMQ_PEER_ADDR "sip:172.19.194.132:5060" ### On Kamailio 1 & 2:### modparam("dmq", "server_address", DMQ_LOCAL_ADDR) modparam("dmq", "notification_address", DMQ_PEER_ADDR) modparam("dialog", "profiles_with_value", "total_dialogs") modparam("dialog", "enable_dmq", 1) route[INITIAL] { ...located at the bottom of the initial route... if(is_method("INVITE") && !has_totag()) { dlg_manage(); } } Cheers, Olli

About SMSC multi-byte support
by shigeru ishida 22 Mar '22

22 Mar '22

Hi all, I have a little question. I tried SMS over IMS on my smartphones with docker_open5gs (using Kamailio and Open5GS), and the multibyte message (Japanese) was garbled at the recipient smartphone. docker_open5gs URL: https://github.com/herlesupreeth/docker_open5gs Also, docker_open5gs uses Kamailio v5.3. I would be very glad if you could tell me about Kamailio's support for multi-byte SMS. Best regards, --Shigeru

Kamailio : Parallel Forking
by Paclinio 21 Mar '22

21 Mar '22

I've been trying to do parallel forking but i've a problem. It's when the conversation ends that the user that is in a private network can't send a bye to kamailio and i don't know why. But the on in public network (4G) can. I think it's related to record_route() or Via but I'm not sure. I'm also trying to use lookup on users that are in my domain but the problem is that I don't know how to go through all my append_branch() and then t_relay. My Audio with RTPENGINE works correctly, the only problem is really this SIP method that doesn't go to kamailio. Config : request_route { route(INVITE); exit; } route[INVITE]{ route(RECORD_ROUTE); route(GROUP_RELAY_SER); switch($tU) { case "112": xlog("MY_SEVERITY"," -- Calling Group Serial"); route(GROUP_RELAY_SER); break; case "113": // This number does not exist (It's not a subscriber). xlog("MY_SEVERITY"," -- Calling Group Parallel"); route(GROUP_RELAY_PAR); break; default: xlog("MY_SEVERITY"," -- Calling Someone"); route(LOCATION); route(RELAY); } exit; } route[RECORD_ROUTE]{ # - remove preloaded route headers remove_hf("Route"); if(is_method("INVITE|SUBSCRIBE")) { # record routing for dialog forming requests (in case they are routed) record_route(); } } route[GROUP_RELAY_PAR]{ t_on_reply("MANAGE_REPLY"); #!ifndef WITH_BRIDGE_ON_FAIL setbflag(FLB_BRIDGE); #!endif route(IPV4V6); route(NATMANAGE); append_branch("sip:9919995@192.168.1.24:5066"); append_branch("sip:9919992@192.168.1.26:5066"); append_branch("sip:9919991@192.168.1.10:5067"); // I Would like to do an IP in my domain and then do a lookup but I don't know how to do it. t_on_failure("GroupFailureRoute"); #Relay (aka Forward) the request t_relay(); break; } # User location service route[GROUP_LOCATION] { $avp(oexten) = $rU; if (lookup_branches("location")){ return (1); } else { return (-1); } } failure_route[GroupFailureRoute]{ t_next_contacts(); while(!route(GROUP_LOCATION)){ // Check if the next user (in serial) is logged in) if (!t_next_contacts()) { send_reply("408","Nobody available"); exit; } } t_on_failure("GroupFailureRoute"); t_relay(); } # Manage incoming replies in transaction context onreply_route[MANAGE_REPLY] { if(status=~"[12][0-9][0-9]") { if(has_body("application/sdp")){ setbflag(FLB_BRIDGE); } route(NATMANAGE); } } ----------------- Sip Trace : 2022/03/21 18:36:46.469257 149.154.195.121:9665 -> 192.168.1.41:5060 INVITE sip:113@192.168.1.41:5060;transport=TCP SIP/2.0 Via: SIP/2.0/TCP 100.79.133.159:5060 ;branch=z9hG4bK-524287-1---4108e717927214fd;rport Max-Forwards: 70 Contact: <sip:9919993@100.79.133.159:5060;transport=tcp> To: <sip:113@192.168.1.41:5060> From: "codec3-public"<sip:9919993@192.168.1.41:5060 ;transport=TCP>;tag=ed51991c Call-ID: GlECSiXh3tJ37DqYLLvm_g..

Kamailio : Serial forking
by Paclinio 21 Mar '22

21 Mar '22

I've been trying to do serial forking, I've configured something that is working but when I'm looking on github and other sources it seems like my code is a little too complicated and I would like to know if there is a simpler config that I can use.

Can Kamailio send an ACK to a final response?
by Marrold 21 Mar '22

21 Mar '22

Hello, I'm exploring using Kamailio as a dumb edge proxy, and as such I want to keep things as lean as possible. In some scenarios I would like the "core" proxies to signal to the edge that a request should be dropped without a response. This could be with a custom header in the reply or perhaps a 444 response ( nginx uses this internally to drop a request without responding ) I have discovered that if I drop the response in the reply_route, the edge proxy doesn't send an ACK and keeps retransmitting the request until it times out, at which point it sends a 408 back to the UA. Is there any way to ACK the response from the core and destroy the transaction? Thanks Matthew
