Asterisk, unable to find dialog for ACK with route param and call-id

by Trevor Peirce

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

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?

More than TCP 800 concurrent calls, slows Kamailio (LUA FILE API REQUESTS)

by Giovanni Jose

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

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

Thanks if someone could highlight my path. Best Regards, -- Youssef

nathelper OPTIONS ping

by Xuo Guoto

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.
