Dynamic UAC Registration
by Mack Hendricks 20 Jan '19

20 Jan '19

Hey All, So, I want to use the UAC module to handle Digest Auth to upstream carriers. But, I don’t know which carrier will be selected until another module (dRouting in this case) tells the logic which carrier to use. I can see in the logs that the uac_auth function can capture the Auth Realm. But, I need to access it from the Kamailio script so that I can lookup the credentials for that realm and then call uac_auth. I’ve tried getting the info from $ar, but that gives me the realm of the inbound request versus the realm of the upstream carrier. Also, I’ve tried using $T_rpl($ar), but that returns 0. Here’s my logic from the Kamailio file: if(t_check_status("401|407")) { $var(reply_realm) = $T_rpl($ar); $var(query)="select auth_username,auth_password from uacreg where realm='" + $var(reply_realm) + "'"; sql_xquery("cb","$var(query)","rb"); xlog("L_DEBUG","[MANAGE_FAILURE: Proxy Auth]: The query is $var(query) auth realm is $var(reply_realm) and the user name is $xavp(rb=>auth_username)"); $avp(auser) = $xavp(rb=>auth_username); $avp(apass) = $xavp(rb=>auth_password); uac_auth(); t_relay(); exit;` } A snippet of the log file is below: Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: exec: *** cfgtrace:failure_route=[DEFAULT_ROUTE] c=[/etc/kamailio/kamailio.cfg] l=1616 a=63 n=assign Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: exec: *** cfgtrace:failure_route=[DEFAULT_ROUTE] c=[/etc/kamailio/kamailio.cfg] l=1617 a=63 n=assign Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: exec: *** cfgtrace:failure_route=[DEFAULT_ROUTE] c=[/etc/kamailio/kamailio.cfg] l=1618 a=24 n=uac_auth Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: DEBUG: uac [auth.c:409]: uac_auth(): picked reply is 0x7f900cb7eaf0, code 407 Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: DEBUG: uac [auth.c:225]: get_autenticate_hdr(): looking for header "Proxy-Authenticate" Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: DEBUG: uac [auth.c:429]: uac_auth(): header found; body=<Digest realm="sip.flowroute.com", nonce="XERJMlxESAbDNCK3INmBfoET1GGxpcyr", qop="auth"> Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: DEBUG: uac [auth_hdr.c:209]: parse_authenticate_body(): <realm>="sip.flowroute.com" state=2 Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: DEBUG: uac [auth_hdr.c:209]: parse_authenticate_body(): <nonce>="XERJMlxESAbDNCK3INmBfoET1GGxpcyr" state=3 Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: DEBUG: uac [auth_hdr.c:209]: parse_authenticate_body(): <qop>="auth" state=1 Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: DEBUG: uac [auth.c:449]: uac_auth(): no credential for realm "sip.flowroute.com" Jan 20 10:05:58 dsiprouter /usr/sbin/kamailio[2871]: exec: *** cfgtrace:failure_route=[DEFAULT_ROUTE] c=[/etc/kamailio/kamailio.cfg] l=1619 a=24 n=t_relay Thanks in advance for any help Mack Hendricks dSIPRouter

Hi We are running Kamailio 3.7 on our production servers. The Kamailio process stopped running on one of the 4 servers. Log shows "segfault error". No core file generated. Any suggestion on how to verify the issue would be appreciated. kernel: [63574875.776269] kamailio[1558]: segfault at 0 ip 000000000055933a sp 00007fffd4ca6700 error 4 in kamailio[400000+211000] /usr/sbin/kamailio[1545]: ALERT: <core> [main.c:785]: child process 1558 exited by a signal 11 /usr/sbin/kamailio[1545]: ALERT: <core> [main.c:788]: core was not generated CRON[21436]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1) Thanks, AL

Mid-Registrar
by Mark Thomas 20 Jan '19

20 Jan '19

I’m currently and OpenSIPS user and I really want to be able to use their software on OpenWRT, but I have found it really hard to cross-compile. Is there a possibility to run Kamailio as a mid-registrar? For my application this is required, and I haven’t been able to find any information on this.

handling BYEs generated by dialog-timeout
by * Paolo Visintin - evosip.cloud 19 Jan '19

19 Jan '19

Hello! I'm wondering if someone have experience in changing $du on local kamailio generated packets (like BYE generated at the dialog-timeout) I'm trying to manipulate in `event_route[tm:local-request]` with no success. In the end I have it working using the `forward()` function and then using `exit;` but in this case instead of having 2 BYEs , kamailio sends 4 BYEs (2 with original $du, 2 with new $du) this an example : event_route[tm:local-request] { if ($rm == "BYE") { route(SELECT_OUTBOUND_PROXY); forward(); exit; } } I'm using a kamailio proxy on top with no record-route (we want to have multiple instances of proxy that can change ip address). Thanks in advance! Paolo

Dev documentation on implementing event_route events in custom module
by Ivan Ribakov 19 Jan '19

19 Jan '19

Is there any documentation for module developers that lays out API for registering and triggering events from a custom Kamailio module (similar to https://kamailio.org/docs/modules/5.0.x/modules/tm.html#tm.event_routes)? I have been referring to https://www.kamailio.org/docs/kamailio-devel-guide/ <https://www.kamailio.org/docs/kamailio-devel-guide/> up until now but it doesn’t seem to cover event_routes. Thanks in advance, Ivan

event_route[usrloc:contact-expired]
by Javier Valencia 18 Jan '19

18 Jan '19

Hi there! I'm using Kamailio 4.4.3, and I add this code to my Kamailio: event_route[usrloc:contact-expired] { xlog("L_INFO", "EXPIRED CONTACT START\n"); xlog("L_INFO", "EXPIRED CONTACT for $ulc(exp=>aor)\n"); xlog("L_INFO", "EXPIRED CONTACT END\n"); } I can't see this entries in the log. I read many times the docs and code, but I don't understand why it's not working. I have two phone with 60 and 300 expiry seconds, if then expire, when it's event_route[usrloc:contact-expired] triggered? Why this event route it's named as usrloc but it's documented in registrar module? I need to provide more info about? Thank you very much.

rtpengine_manage() in async tasks
by Alex Balashov 18 Jan '19

18 Jan '19

Hi, I've run into an issue with handling reinvites in async task workers--which I need to do in order to introduce a small delay to avoid a UA race condition--in which some state that is necessary for rtpengine_manage() to do the right thing seems to be lost. Specifically, if I do this: -- loadmodule "mqueue" loadmodule "rtimer" ... modparam("rtimer", "timer", "name=reinvite_q1;interval=10000u;mode=1;") modparam("rtimer", "exec", "timer=reinvite_q1;route=REINVITE_DEQUEUE") modparam("mqueue", "mqueue", "name=reinvite_q"); ... route { ... if(has_totag()) { if(loose_route()) { ... if(is_method("INVITE")) { if(!t_suspend()) { sl_send_reply("500", "Server Internal Error"); exit; } mq_add("reinvite_q", "$T(id_index):$T(id_label)", ""); } else route(IN_DLG_REQ); exit; } ... } route[REINVITE_DEQUEUE] { while(mq_fetch("reinvite_q")) { $var(id) = $(mqk(reinvite_q){s.select,0,:}{s.int}); $var(label) = $(mqk(reinvite_q){s.select,1,:}{s.int}); t_continue("$var(id)", "$var(label)", "IN_DLG_REQ"); } } route[IN_DLG_REQ] { handle_ruri_alias(); if(is_method("BYE")) rtpengine_manage(); else if(is_method("INVITE") && sdp_content()) rtpengine_manage("replace-origin replace-session-connection ICE=remove") t_on_reply("MAIN_REPLY"); if(!t_relay()) sl_reply_error(); } onreply_route[MAIN_REPLY] { if(is_method("INVITE") && sdp_content()) rtpengine_manage("replace-origin replace-session-connection ICE=remove"); } -- What I find is that if I generate a reinvite from either side, rtpengine_manage() passes through the SDP offer in the reinvite unadulterated, although the answer returns properly adulterated by RTPEngine. The same thing occurs if I use 'async', which as I gather is just a wrapper of convenience around t_suspend/t_continue() anyway. That module won't do for my purposes because I need a millisecond-level delay resolution rather than second-level, anyhow. Anyway, surely enough, this is because the execution context is one that insinuates a stream deletion. When the reinvite offer comes across and I call rtpengine_manage(), the command sent is 'delete': -- Jan 14 20:24:23 staccato.evaristesys.com rtpengine[33830]: INFO: [c94347dcf92e7ccc10dee84c4e0d1c8a]: Received command 'delete' from 209.51.167.66:39788 -- The RTPEngine module documentation actually warns about this: https://kamailio.org/docs/modules/5.2.x/modules/rtpengine.html#rtpengine.f.… But this insight is buried in the fourth bullet point: "If BYE or CANCEL, or called within a FAILURE_ROUTE[], then call rtpengine_delete(). Be careful with calling this function after resuming a suspended transaction (e.g., after t_continue()), because the context of executed route is FAILURE ROUTE (in other words, rtpengine_manage() in the route block of t_continue() does the same as in failure_route)." This would lead one to believe that it applies only in the context of handling a BYE or CANCEL in a resumed transaction, when in fact it seems to hold true of non-BYE/CANCEL and non-failure contexts as well, as can be clearly seen with the reinvite. The behaviour is exactly as expected if I don't use rtpengine_manage() and instead manually call rtpengine_offer()/rtpengine_answer(). And expected behaviour comes from rtpengine_manage() if I don't handle the request in a resumed transaction context. This yields the fundamental question: Is there any way to have my cake and eat it too? I really want to use rtpengine_manage() because I need to handle a potential SDP offer-in-ACK scenario and don't want to do a bunch of state-keeping in order to use the correct choice of rtpengine_{offer|answer}() in the right context, which is a problem rtpengine_manage() solves beautifully. At the same time, I absolutely need the slight reinvite delay that can be accomplished via async processing; a UA on this side has a nasty habit of sending a reinvite almost simultaneously to the 2xx answer for the INVITE transaction, leading to indeterminate egress velocity for those respective messages out of Kamailio worker threads.

authentification issue when nb user increase
by Laurent Schweizer 18 Jan '19

18 Jan '19

Hello, I have a proxy with Kamailio 5.0.6 working since few month without any issue. Around 4500 locations and 5300 contacts This weekend we move a very old proxy (Kamailio 3.3.2 with an old server )to this new one, adding around 14’000 users and 15’000 contacts. Yesterday when calls was starting we get an big issue with this new proxy, lot of phones was disconnected and some calls was rejected. I see that the issue was the authentication (done via a mysql DB with the cluster db module) many phone get a failure and was disconnected, mostly phone connected via TCP or TLS we see less issue with UDP even we have much more . The issue was not the number of TCP/TLS connection as we see the REGISTER and the 401 going back, so connection was correctly done Currently it’s working but I don’t know exactly why ☹, I mean I have done a change but it has really no relation … , during the same time I get another issue, some calls have no voice… We are using rtpengine (on the old proxy we was using rtpproxy) and with the rtproxy we already face a long time ago such case and to solve it we setup multiple rtpproxy (on the same host) So I try to do the same, I setup a second rtpengine on the same host and when I reload the config with : kamcmd rtpengine.reload all registration was working perfectly ... As they is no relation with the registration end the rtpengine I don't know why now it's working. Any idea ? BR Laurent

Limitation in Dispatcher Probing
by Duarte Rocha 17 Jan '19

17 Jan '19

Greetings, I have a question about Dispatcher's probing. I have it configured with ds_probing_mode = 3 and ds_ping_interval = 60. Currently i have 35 Gateways with state = 8, meaning they will be probed. However, when i do a SIP capture i get a different scenario. Altough Kamailio sends OPTIONS at every 60 seconds it only sends to 16 destinations. Is there a configuration that limits this? What can i do to have every gateway probed? Best Regards, Duarte Rocha

AWS binat external -> internal routing and record_route
by Dmitry Sytchev 17 Jan '19

17 Jan '19

Hi all! I have a question that arises in mailing list sometimes, but it is still not clear for me how to work with this. We have AWS instance with standard Amazon bi-nat, so basically communication with external hosts works with listen udp:ip:port advertise ip:port But in case when we need to send external call to internal network by internal ip addresses, we want to have internal host in record-route. As far as I understand, basic recommendation is to use separate port or internal address and select it with appropriate function. Maybe it is more theoretical question, but can we do something to generate correct record-routes and VIA for calls coming from external network to make their softswitches happy, and still maintain internal address in messages going to internal hosts, using single host and port on Kamailio behind nat? Thanks! -- Best regards, Dmitry Sytchev, IT Engineer

Setting up Kamailio IMS in a Box difficulties.
by Jason Tsay 17 Jan '19

17 Jan '19

Hi miconda, I am new to the Kamailio and RCS world. I'm trying to set up an IMS core so I can get two devices communication through RCS. I am trying to set up the Kamailio IMS in a box vmware image, and when I boot it up, it asks for the server login information. ??All parameters and passwords used are documented in the log-file.? I couldn't find documentation for the username and password. I was wondering if there is a new link available or login information where I could see the set up. These are the things that I have found (to be working) getting started - https://www.kamailio.org/w/2016/02/kamailio-ims-getting-started-box/ configs - https://www.dropbox.com/s/nm51v4orxrox4ac/Kamailio-IMS%20config-files.zip?d… pdf - https://www.kamailio.org/docs/tutorials/ims/Kamailio-IMS-in-a-Box.pdf I did find the config files in a dropbox but I wanted to get the vmware sandbox working so I have a working environment (as I have failed many times to get my own instance set up.) In addition, I was looking for some Android clients or if you could recommend some. I've tried rcsjta but I keep getting an API not compatible error (Doesn't work on Android Pie (Pixel 3 device) or Android M (6.0.1) Nexus device.) I also tried IMSdroid, and it looks like it works with Android M (6.0.1) Nexus device but not compatible with Android Pie. Thanks, Jason

Updating default kamailio.cfg to use rtpengine
by Daniel-Constantin Mierla 16 Jan '19

16 Jan '19

Hello, being discussed at events offline or during irc meetings couple of times, I want to open the discussion about updating the default configuration file to use rtpengine. So far I let rtpproxy because was packaged in many Linux distros, however, given the benefits of rtpengine in terms of performance as well as webrtc support, doubled by the fact that nowadays in the community it seems to be the primary choice of rtp relay, we should decide what to do. I see two options: 1) add a define to allow selection between rtpproxy and rtpengine 2) replace rtpproxy completely with rtpengine I would prefer 2) for simplicity of the configuration file, but the main question for the users community is how easy they find the deploying of rtpengine. Using Debian/Ubuntu should be trivial, there are packages for it, but I do not know about CentOS, Fedora, openSUSE or other Linux/BSD OSes people here are using it. Reply to sr-users if you have an opinion on this matter (I cc-ed sr-dev mainly to make aware the devs, but it is a matter of using kamailio). Of course, other suggestions are welcome as well.

DMQ tries to resolve dns AAA even when it is disabled in kamailio core config

Hi all, I'm using DMQ with multi_notify set to 1, the dns_try_ipv6 is disabled and dns_cache_flags is set to 1, but even this way DMQ is making dns AAA queries.

Overhead of health check with dispatcher
by Jesse Strahn 16 Jan '19

16 Jan '19

Hi all, I'm new to Kamailio. I am using Kamailio/dispatcher to distribute calls to several SIP IVRs. I'm trying to determine the best solution to autoscale in AWS when call capacity of the IVRs is reached. The most straight forward solution is to spin up a new IVR on a dedicated subnet when required. I would configure dispatcher such that the whole IP range of this subnet is in the dispatcher.list so that once a new instance becomes available, Kamailio starts sending calls there. My question is, how much overhead would this add as Kamailio/dispatcher would be polling the IPs in the subnet that were not yet active. The plan would be to have a /28 subnet with 16 IPs. To start, there would be 2 active IVRs up and responding and 14 IPs in dispatcher.list that would not be responding. Appreciate any insight. Thanks, Jesse
