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.

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. To have more precision, I'm using RTPENGINE and I need to be able to go through NAT. My Config : request_route { route(INVITE); exit; } route[INVITE]{ route(RECORD_ROUTE); route(GROUP_RELAY_SER); switch($tU) { case "112": // This number does not exist (It's not a subscriber). xlog("MY_SEVERITY"," -- Calling Group Serial"); route(GROUP_RELAY_SER); break; case "113": xlog("MY_SEVERITY"," -- Calling Group Parralelle"); 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_SER]{ t_on_reply("MANAGE_REPLY"); route(IPV4V6); route(NATMANAGE); (RTP Routing is working correctly) append_branch("sip:9919995@192.168.1.41","1"); append_branch("sip:9919992@192.168.1.41", "0.2"); append_branch("sip:75575757@192.168.1.41", "0.4"); append_branch("sip:9919991@192.168.1.41", "0.5"); t_load_contacts(); t_next_contacts(); while(!route(GROUP_LOCATION)) { if (!t_next_contacts()) { send_reply("408","Timeout or nobody available"); exit; } } 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)){ 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); } } --------------------------------- Here's The SIP Trace : 2022/03/21 18:28:45.265009 149.154.195.121:9665 -> 192.168.1.41:5060 INVITE sip:112@192.168.1.41:5060;transport=TCP SIP/2.0 Via: SIP/2.0/TCP 100.79.133.159:5060 ;branch=z9hG4bK-524287-1---75083bb7c6ed8a35;rport Max-Forwards: 70 Contact: <sip:9919993@100.79.133.159:5060;transport=tcp> To: <sip:112@192.168.1.41:5060> From: "codec3-public"<sip:9919993@192.168.1.41:5060 ;transport=TCP>;tag=35ce2334 Call-ID: RtH8fBIrIgUYPAkxlxjI4Q..

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
