Version 5.4 contact rewrite/restore functions docs?
by Dmitry Sytchev 22 Jan '21

22 Jan '21

Hello! In 5.4 release announce there is a line about contact rewriting. "new Contact address encoding/decoding functions – replace/restore Contact address with SIP server address, by encoding/decoding old address in a parameter" Where can I find some documentation or examples about NEW functions? At present we handle this task exactly the same way via parameters manually. It is kinda verbose and hard to understand. Maybe new functions will simplify this. Please advise! Thanks! -- Best regards, Dmitry Sytchev, IT Engineer

I'm having a problem installing kamailio 5.4 using the following guide https://kamailio.org/docs/tutorials/5.4.x/kamailio-install-guide-git/ . I have a debian 10.7 machine where I install default-mysql-server package for the database.

[kamailio 5.4.3] xavp_rm_by_index removes (N+1) first indexes instead of index N
by Chaigneau, Nicolas 20 Jan '21

20 Jan '21

Hello I’m trying to use function xavp_rm_by_index to remove a specific index from a given xavp. I’m observing an unexpected behaviour, I think it might be a bug : Instead of just removing the index, the function removes the index and all others before it. E.g : if called with « idx = 1 », it removes indexes 0 and 1. Reading the code of xavp_rm_internal (which is called by xavp_rm_by_index), I don’t think it behaves at it should : /* Remove xavps * idx: <0 remove all xavps with the same name * >=0 remove only the specified index xavp * Returns number of xavps that were deleted */ For example when I do this : LM_ERR("COUNT BEFORE: %d\n", xavp_count(rname, NULL)); int rm_count = xavp_rm_by_index(rname, 1, NULL); // TEST LM_ERR("REMOVED: %d\n", rm_count); LM_ERR("COUNT AFTER: %d\n", xavp_count(rname, NULL)); « rm_count » returned is 1 (which is expected). However, « count after » is decremented by 2. And when I look at the contents of my xavp, I notice that the first two elements have been removed. Likewise if xavp_rm_by_index is invoked with idx = 2 => the first 3 elements are removed. So… do you think this is a bug ? or something I didn’t understand ? Thanks for your help ! Regards, Nicolas.

Dialog Tracking with Inconsistent RR
by Charles Phillips 20 Jan '21

20 Jan '21

I am working to track concurrent channels with the dialog module, but I have run in to an issue. Due to the nature of my required configuration, I have a need to strip the record route headers from packets that are sent to the upstream proxy. This leaves no way for the dialog module to track the state of the call. I was hoping that DID_FALLBACK or DID_NONE modes would track by call id or some other constant, but it does not appear to. So, before I start down the path of using htable to store and reinsert the did when a packet returns, is there something I am missing with dialog? Is there some more efficient way to do this? - Charles

Header Manipulation with returned REST data
by Mark Lawrence 19 Jan '21

19 Jan '21

Hi All, Sorry for the intrusion and asking directly, but there’s so much information out there that I would spend years looking for the answer myself and spending equal amount of time in a lab playing. I do like the last idea but time is a little short. I’m thinking of using Kamailio to overcome a few downfalls in the main SBC/PBX commercial product space that I’ve typically deployed and wanted to ask if it is possible to use as a stateful proxy and carry out the following header manipulation type scenario with a bit more dynamassium: Use the FROM and TO header to create two value pairs that would be sent via a REST request to an external application, which will return two corresponding values to (a) supply a different value to update the original FROM header and (b) a full PAI sting to add on to the outgoing message. If you have experience of this or if it’s a nonstarter I’d love to know. There’s so many modules and great stuff that you have in your toy chest it is amazing and kudos to all you developers being so inventive out there: it leaves me to think I’ve been deploying SIP wrong all these years. Thanks and keep safe and well, Mark

Kamailio High Availability questions
by Andriano 17 Jan '21

17 Jan '21

Hello have some questions about Kamailio HA + loadbalancers (dispatcher modules) 1. is posible to make HA for RTP media? maybe RTPEngine +redis? is not possible to do this with RTProxy? where is some examples? 2. What do Kamailio db cluster module? it can replicate every DB query record like normal DB cluster? or better is to use native MySQL cluster mode? 3. How is working dispatcher modules in HA? how call is handled and htable in memory between loadbalancers endpoint nodes etc... IS it posible to do only with DMQ ? Just need understand how to do basic Kamailio setup with HA and load balancers in general, for example if will be 2 phisical servers, in every server is virtualisation and every server has 2 VPS. 1 VPS for frontend Kamailio loadbanancer, 1 VPS backend Kamailio app with accounts, routing logic, LCR, RTP media app etc... between load balancers i know maybe is possible to do floating ip, dns round robinetc... and if one VPs server down, call will be dropet in every situation? or call will not be droped and how to prevent it. Just need to know in general schema and architecture how to do this real HA in Kamailio and avoind sinlge point of failure and where to read and learn it ho to make HA in real. In the internet no many docs about it, many conference video how good it is, but no good examples with config, i did not founded, so will be very glad for any help in these newbie questions ;) with single kamailio is many answers, but is realy difficult to understand how to do voip HA with Kamailio without single point of failure. Thanks for any answers...

Hi everyone. I wanted all of you to know, that I have made JavaScript stubs, for autocompletion in IDE’s, for those of you that use KEMI JavaScript. Specifically tested on Jetbrains PHPStorm/Webstorm. The stubs are available for free at my GitHub page. The link is https://github.com/captainDuckay/Kamailio-javascript-stubs My main language isn't typescript or JavaScript, and this is one of my first public releases. With that said though, I am open for critics, or even guidance. I hope it's usable for you. // Nicki Bo Otte

Source Port on TLS OPTIONS from Dispatcher
by Charles Phillips 14 Jan '21

14 Jan '21

Hello all. As they say in radio, “long time listener, first time caller” Anyway, I am having trouble getting past the following road block and any help would be greatly appreciated. Kamailio version is 5.4.3 When attempting to use dispatcher to send OPTIONS packets to several TLS destinations, the packets are leaving the Kamailio server on random ports. This is a problem because the servers I am sending the OPTIONS to (MS Teams) are enforcing rport so the responses are returned to a port that Kamailio is not listening on. I have tried to force the socket in the event route (relevant parts of snippet below) but it does not appear to help. I should also mention that I am not behind NAT and the TLS socket is specified in the dispatcher attrs. event_route[tm:local-request] { sip_trace(); $fs = “tls:**ip-address**:5061”; } I have used Kamailio as a TLS server for many projects, but this is my first time as a client. I am sure I am missing something. - Charles

BYE and TCP
by Kjeld Flarup 13 Jan '21

13 Jan '21

Hello I have a Kamailio running behind NAT, which sends calls to a VOIP service provider. I have setup the Kamalio to listen on port 5071, and also setup a port forward in the router. Now the problem is that with TCP, 5071 is not used for the dialog, but a new port is chosen everytime. This means that when the mobile phone called hands up, I never sees the BYE, because BYE is a new dialog. To which port is the server supposed to send the BYE, and what field tells the server this. -- -------------------- Med Liberalistiske Hilsner ---------------------- Civilingeniør, Kjeld Flarup - Mit sind er mere åbent end min tegnebog Sofienlundvej 6B, 7560 Hjerm, Tlf: 40 29 41 49 Den ikke akademiske hjemmeside for liberalismen - www.liberalismen.dk

We want know how can we do for convert or modify the REFER message into INVITE for finally transfer the call. kamailio -v: version: kamailio 5.4.2 (x86_64/linux) 4fdc21 flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 4fdc21 compiled on 20:43:45 Dec 1 2020 with unknown Uname -a: Linux proxy 4.15.0-124-generic #127-Ubuntu SMP Fri Nov 6 10:54:43 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux rtpengine -v: Version: 9.2.0.0+0~mr9.2.0.0 git-master-aa5e0244

TSILO - transaction is not suspended
by Jeremy McNamara 11 Jan '21

11 Jan '21

Hi Folks - I am attempting to set up a mobile push configuration, by following the published example(s). If we have more than one endpoint registered, this configuration works as expected (via the ts_store() path below). If we do not have another registered endpoint the transaction seems to be suspended but then cannot be resumed (t_suspend) after REGISTER arrives.

Profile name as variable in set_dlg_profile
by Muhammad Sohaib 11 Jan '21

11 Jan '21

Is it possible to insert the current dialog into the profile by using the following way? modparam("dialog", "profiles_no_value", "mytest;xyz") $var(profilename)="xyz"; set_dlg_profile(" $var(profilename) "); Currently it is giving errors and not allowing to use variable instead of static profile name. Or is there any alternative to pass profile name as variable? --- Thanks,

uac.reg_refresh command
by Javier Valencia 11 Jan '21

11 Jan '21

Hello, I'm playing with RPC on my Kamailio 4.4.7, and I getting rare behaivor with *uac.reg_refresh* command. When I run it thru kamcmd like docs describes, this is without *l_uuid* parameter, I'm geting "*error: 500 - Invalid Parameters*" output. And when I run with *l_uuid* parameter, I get no output. But in both cases, Kamalio don't refresh data from DB. But I run this command thru HTTP (JSONRPC-S), both call modes are equivalent. With or without l_uuid parameter geting no output and refresh data from DB. It's a normal behaivor?

how does rtjson work?
by Syed Shahryar 11 Jan '21

11 Jan '21

My use case is such that I want to be able to send a SIP MESSAGE destined for a single username to multiple users. In order to be able to map that target username to multiple usernames, I tried using rtjson and evapi/http (to generate the routing json), but none of them worked. Is it the right approach? Is there any other way to programmatically generate multiple targets for SIP request? I am familiar with dynamic routing but I need more flexibility. Initially, I tried sending the request to a different username but that didn't work and got the following message in the http async result route. kamailio | 19(25) ERROR: nathelper [nathelper.c:1461]: sdp_1918(): Unable to parse sdp body kamailio | 19(25) NOTICE: <core> [core/kemi.c:124]: sr_kemi_core_notice(): In evapi msg branch kamailio | 28(34) NOTICE: {2 6661 MESSAGE q6hikd6tumsr1dh35kvj} <core> [core/kemi.c:124]: sr_kemi_core_notice(): In evapi reply branch The message was received on the originally requested to user and also $tu still points to the original user instead of the new user even after executing the following code. KSR.rtjson.init_routes(response); KSR.rtjson.push_routes(); KSR.nathelper.fix_nated_contact(); In http response, I receive the following and don't see any rtjson errors when init_routes is executed on it. {"version":"1.0","routing":"parallel","routes":[{"headers":{"from":{"display":"test_1","uri":"sip: *test_1*@test.com:9908"},"to":{"display":"test_4","uri":"sip:*test_4*@ test.com:9908 "},"extra":""},"branch_flags":8,"fr_timer":5000,"fr_inv_timer":30000}]} Please note that the request was sent to *test_2*(a)test.com. I have tried other combinations of above but nothing works. I have already searched on Google and read relevant articles and blog posts.

Lost MySQL connections - Error 500
by Duarte Rocha 11 Jan '21

11 Jan '21

Hi all, I've made a post last month regarding losing MySQL connections - https://lists.kamailio.org/pipermail/sr-users/2020-December/111389.html At the time I thought connections were dying as a consequence of low activity and traffic on the proxy. Meanwhile, I've migrated a great number of equipments to the proxy with Registers being refreshed every 10minutes and the problem still persists. In order to try to fix this i've added timeout_interval and ping_interval from the db_mysql module. My SQL client on the Kamailio machine is mysql-community-client 5.6.50-2.el7. It writes and reads in a remote InnoDB database. This are the logs i get from Kamailio when the problem appears : Jan 7 09:43:27 sbc_bbt01_active /usr/local/kamailio-5.4/sbin/kamailio[21735]: ERROR: {1 27880 REGISTER e5f8f7bc-cbb2-40b3-9037-edacd6276a2b} db_mysql [km_dbase.c:123]: db_mysql_submit_query(): driver error on query: Lock wait timeout exceeded; try restarting transaction (1205) Jan 7 09:43:27 sbc_bbt01_active /usr/local/kamailio-5.4/sbin/kamailio[21735]: ERROR: {1 27880 REGISTER e5f8f7bc-cbb2-40b3-9037-edacd6276a2b} <core> [db_query.c:348]: db_do_update(): error while submitting query Jan 7 09:43:27 sbc_bbt01_active /usr/local/kamailio-5.4/sbin/kamailio[21735]: ERROR: {1 27880 REGISTER e5f8f7bc-cbb2-40b3-9037-edacd6276a2b} usrloc [ucontact.c:1147]: db_update_ucontact_ruid(): updating database failed Jan 7 09:43:27 sbc_bbt01_active /usr/local/kamailio-5.4/sbin/kamailio[21735]: ERROR: {1 27880 REGISTER e5f8f7bc-cbb2-40b3-9037-edacd6276a2b} usrloc [ucontact.c:1663]: update_contact_db(): failed to update database Jan 7 09:43:27 sbc_bbt01_active /usr/local/kamailio-5.4/sbin/kamailio[21735]: ERROR: {1 27880 REGISTER e5f8f7bc-cbb2-40b3-9037-edacd6276a2b} registrar [save.c:784]: update_contacts(): failed to update contact Jan 7 09:43:27 sbc_bbt01_active /usr/local/kamailio-5.4/sbin/kamailio[21735]: ERROR: {1 27880 REGISTER e5f8f7bc-cbb2-40b3-9037-edacd6276a2b} sl [sl_funcs.c:414]: sl_reply_error(): stateless error reply used: I'm terribly sorry, server error occurred (1/SL) Originally I had usrloc db_mode on mode 3 - DB-Only Scheme. In order to try to mitigate the issue I changed it to mode 1 - Write-Through scheme but even then I get the same log errors and an "500" error is still sent to the client. I chose this mode since, as far as I can understand it applies changes directly to DB but also uses cache. Please correct me if i'm wrong on that. Has this issue happened with anyone before? Is there a way to mitigate this issue? My only constraint is that I need the database to be always updated since I have an HA setup, and as such, I can't use cache only methods. Best Regards,

loose_route() - Local Proxy
by Duarte Rocha 08 Jan '21

08 Jan '21

Greetings, I'm using loose_route() from the RR module and i'm having troubles making it use the following exception from the code : "There is only one exception: If the request is out-of-dialog (no to-tag) and there is only one Route: header indicating the local proxy, then the Route: header is removed and the function returns FALSE." My example is a REGISTER without To-TAG which has a Route header with kamailio address. If i use proxy IP on Route header , loose_route() returns false as it should. However, if i use an hostname belonging to the proxy in the route, loose_route() returns true. I have hostnames and local ips defined in the "DOMAIN" table but it doesn't seem to be working. Which other places can local hostnames and ips be configured in order to be seen as local to loose_route() ? Best Regards

in my requirement call coming from sbc to kamailio proxy and we route to pbx server in that when kamailio proxy get the call at that time i am removing Contact header using remove_hf("Contact") and adding contact Header using append_hf("$uac_req(hdrs)") for route to PBX server . in that signaling i am getting modified Contact header but old contact header not removed properly some junks are remain in the signaling scenario : SBC ---------> Kamailio proxy ------> PBX before using remove_hf("Contact") INVITE sip:user2@ <sip%3A5678(a)opensips.org>domain.org;transport=UDP SIP/2.0 Via: SIP/2.0/UDP 10.212.xxx.xxx:port;branch=z9hG4bK-524287-1---8c5ac8642f321a9e Max-Forwards: 70 Contact: <sip:user1@10.212.xxx.xxx:39931;transport=UDP> To: <sip:user2@ <sip%3A5678(a)opensips.org>domain.org;transport=UDP> From: <sip:user1@ <sip%3A1234(a)opensips.org>domain.org ;transport=UDP>;tag=891fd646 Call-ID: t9Ff-fCrin_VN1IO9Xf1mA..

Dispatcher SNI Questions
by Tim Chubb 06 Jan '21

06 Jan '21

Hi All Is it possible to explicitly define the tls cert to be used per destination by dispatcher? I'm attempting to integrate with a service that requires domain name presented to match that of the cert. Where the use of dispatcher is probably not as intended anyway as it targets the same set of destinations multiple times (primary and secondary endpoints for the service im integrating with), with multiple distinct set id's (basically a set per customer for multi tenancy) which expects a sip ping per account to verify that connection is alive and healthy. #Example Dispatcher list #Account 1 1 sip:a.cloudservice.com:5061;transport=tls 8 1 socket=tls:10.0.0.2:5061;ping_sni=sip.account1.com;ping_from=sip:sip.account1.com:5061 1 sip:b.cloudservice.com:5061;transport=tls 8 1 socket=tls:10.0.0.2:5061;ping_sni=sip.account1.com;ping_from=sip:sip.account1.com:5061; #Account 2 2 sip:a.cloudservice.com:5061;transport=tls 8 1 socket=tls:10.0.0.2:5061;ping_sni=sip.account2.com;ping_from=sip:sip.account2.com:5061; 2 sip:b.cloudservice.com:5061;transport=tls 8 1 socket=tls:10.0.0.2:5061;ping_sni=sip.account2.com;ping_from=sip:sip.account2.com:5061; Currently I'm running a solution based around certs with multiple SAN (subject alternative name) defined, but this is a pain to administrate, and not as scalable as I would like. I want to be able to define multiple client:any tls profiles and explicitly send via that profile. Its easy enough to do that in config using the tls xavps to define a server name and/or id. But for the sip options ping by dispatcher to work you need to specify the server name or id before the tm:local-request event route fire's. I've resorted to hacking away at dispatcher to see what would happen if I set the tls server name or id before the OPTIONS message is sent, and it works great for the first tls client profile matched, but any others you define re-use the initial tcp connection so reuses the first connections tls config, thus presenting the wrong cert (I'm probably wrong but logs show only one tls complete_init() related to dispatcher pings and the second set's pings skips all the tls init logging so suggests some thing is cached/reused, and logging on the service indicates cert name mismatch with set1s cert being offered) So I've hit a bit of a dead end, is there a way to force a new tcp connection per server name/id I fear outbound SNI might be a bit of a can of worms, for it to work nicely with dispatcher as is, would be an extension of the proto:host:port format to include a name or id, maybe something like: tls(name=sub.domain.com):10.0.0.5:5061 But that looks like it would have a lot of wide reaching knock-on effects, so setting it as an attribute like ping_from works fine as I'm currently doing, if I could force a new connection from dispatch.c.... The other thing that's occurred to me is that it might be better to stop trying to adapt a small percentage of dispatcher's functionality and trying to hammer a round peg into a square hole and instead try and create a new module similar to dispatcher in so much that it sends pings (that's all I really need in this case) and use dispatcher as intended with a single set of non-repeated destinations for routing. This would also allow much simpler integration with MS teams (if added ability to set contact address on the background pings) as well as the service im trying to integrate, and a more natural data set to be used as in my example you can see the only difference is the customers domain between each set. How I would imagine it to work would be to create a tls connection per customer domain, then iterate through the connections per destination in pseudo json the data would look like this: { Destinations:[ [1,["a.cloudservice.com","b.cloudservice.com"]], [2,["sip.pstnhub.microsoft.com", "sip2.pstnhub.microsoft.com", "sip3.pstnhub.microsoft.com"] ], Sources:[ {uri:"sip.account1.com",destinationMapping:[1]}, {uri:"sip.account2.com",destinationMapping:[1,2]} ] } And would just run in the background sending pings with SNI support, and if based on dispatcher should make it easy enough adapt things like the destination up and down event routes, and would allow me to use Kamailio much like I would use nginx for web stuff as a reverse proxy and handle TLS offload on my edge gateway proxy. Any thoughts?, im frustratingly close to having something that will do if I could get a new connection to be created, but I fear my use case might be sufficiently different from dispatchers to make a new module a sensible approach.. Regards Tim.

Pre-loaded routes verification
by Duarte Rocha 04 Jan '21

04 Jan '21

Greetings, I'm doing a migration from a opensips system to kamailio one and i'm trying to replicate its functionalities. The system is a Registrar with a pstn gateway. I noticed that on the opensips version, loose_route() is called on initial requests and it seems to be used to protect against preloaded routes. However, on the default Kamailio configuration file loose_route() is only called on requests in-dialog and the verification mentioned above is not used. Why doesn't Kamailio includes this verification? Is there are any security concerns not using it? Best Regards,

Using a specific log level for "script" ?
by Chaigneau, Nicolas 04 Jan '21

04 Jan '21

Hello, Is it possible to set a specific log level for the Kamailio script ? I've seen that the < debugger > module allows to do that with modules or < core > : https://kamailio.org/docs/modules/5.4.x/modules/debugger.html#dbg.p.mod_lev… So I've tried to do : modparam("debugger", "mod_level_mode", 1) modparam("debugger", "mod_hash_size", 5) modparam("debugger", "mod_level", "my_module=3") // this works modparam("debugger", "mod_level", "core=3") // also works modparam("debugger", "mod_level", "script=3") // nope... But it doesn't seem to work for < script >... :/ Regards, Nicolas. This message contains information that may be privileged or confidential and is the property of the Capgemini Group.

[Presence] publ_cache=2 usage
by Denys Pozniak 30 Dec '20

30 Dec '20

Hello! Could somebody explain how the parameters *publ_cache=2* and *subs_db_mode* depend on each other? Do I understand correctly that only the following modes of *subs_db_mode* are allowed 0,1,2? *subs_db_mode:0 - This disables database completely. Only memory will be used. Subscriptions will not survive restart. Use this value if you need a really fast presence module and subscription persistence is not necessary or is provided by other means.1 - Write-Through scheme. Subscriptions are updated synchronously in database and in memory(used for read operations). Use this scheme if speed is not top priority, but it's important that no subscriptions will be lost during crash or reboot or if you have an external application that reads the state of the subscriptions from database and they need to be updated synchronously.2 - Write-Back scheme. This is a combination of previous two schemes. All changes are made to memory and database synchronization is done in the timer. The timer deletes all expired contacts and flushes all modified or new subscriptions to database. Use this scheme if you encounter high-load peaks and want them to process as fast as possible. Latency of this mode is much lower than latency of mode 1, but slightly higher than latency of mode 0. To control the interval at which data is flushed to database, set the db_update_period parameter.3 - DB-Only scheme. No memory cache is kept, all operations being directly performed with the database. The timer deletes all expired subscriptions from database. The mode is useful if you configure more servers sharing the same DB without any replication at SIP level. The mode may be slower due the high number of DB operation.* -- BR, Denys Pozniak

Presence - issue with NOTIFY "terminated" state
by Zhan Bazarov 29 Dec '20

29 Dec '20

Hello everyone! I faced some unfortunately issue with presence module. Let me describe setup scheme a bit: I'm publishing dialog states via pua_dialoginfo from one kamailio server(for calls proccessing itself) to another one kamailio(standalone kamailio just for handling presence,blf,mwi etc) So, about issue, let's say we have device A which has outgoing subscription to extension which belongs to device B and device C(both devices has same extension but different usernames, webrtc+sip phone, effectively its the same Phone, I'm using pubruri_avps to change entities from usernames to extension) . And, in some cases,for examle, when thirtparty is making call to this extension(B,C devices) and making CANCEL after couple seconds - I see the PUBLISH from callserver to presence server with state "terminated', I see 200ok response.. but presence server isn't sending NOTIFY to device A about state "terminated", everything is good with "trying" and "early" states... That problem is happening 1 of 50 tries.. I've tried a lot of things to fix that - still are not succeed. p.s. everything is good from logs/sip point of view... And also, when I disable the webrtc device - I'm not able to reproduce that issue anymore. Looks like something wrong with case, when you have multiple different username behind the same presentity. Maybe someone had same issue and may help me. Thanks! -- Sent from: http://sip-router.1086192.n5.nabble.com/Users-f3.html

Kamailio as a presence watcher
by Jukka Heikkilä 29 Dec '20

29 Dec '20

Hello, I'm working with IMS network and VoLTE related services. My problem is that I would like to use Kamailio as a presence watcher but I haven't managed to make it happen yet. The approach would be that once Kamailio gets 3rd party registration from S-CSCF the Kamailio would send SUBSCRIBE back to S-CSCF to subscribe the presence of subscription. Once a subscription place or get calls the status of subscription would be updated to Kamailio and to the database where it can be fetched. I have checked presence and pua modules, but haven't found a way to make it work as expected. Is there way to do that or is this totally incompatible approach to do that? Best Regards, Jukka Heikkilä jutsco(a)gmail.com

How to implement a self-sustained Presence server
by Michel Pelletier 28 Dec '20

28 Dec '20

Hi, What is the recommended practice for implementing a self-sustained Presence server from my current Kamailio configuration? That is I want the Presence module to be fed status updates as Kamailio is routing calls and handling registrations. So when a user registers, his phone is ringing, he is on the phone, etc.., the Presence module gets notified and can update its subscribers accordingly. Must I add snippets of codes to all of these events and generate local Publish messages, or is there a better way? I'm using the latest version 5.4.x. Regards, Michel Pelletier

This document contains information about: - Real-Time Communications developer room (devroom) - speaking opportunities - volunteering New rules for the online edition -------------------------------- This year FOSDEM will be fully online instead of being held in Brussels, here are the most important things to know about this (quite significant) change: - The reference time will be Brussels local time (CET) - Talks will be pre-recorded in advance, and streamed during the event - The Q/A session will be live - A facility will be provided for people watching to chat between themselves - A facility will be provided for people watching to submit questions Call for participation - Real Time Communications (RTC) ------------------------------------------------------- The Real-Time devroom is about all things involving real-time communication, including: XMPP, SIP, WebRTC, telephony, mobile VoIP, codecs, peer-to-peer, privacy and encryption. **We are looking for speakers for the devroom and volunteers who can help manage the scheduling and live Q&A sessions.** The devroom is only on Saturday, 6th of February 2021. To discuss the devroom, volunteer or ask questions, please join the [Free-RTC mailing list](http://lists.freertc.org/mailman/listinfo/discuss). ### Key dates - 20th Dec: Submission deadline (extended to 8 January) - 24th Dec: Announcement of selected talks - 15th Jan: Presentations upload deadline - 6th & 7th Feb: Conference dates (online) - 6th Feb: RTC devroom date (online) ### Speaking opportunities Note: if you used FOSDEM Pentabarf before, please use the same account/username Real-Time Communications devroom: deadline 23:59 UTC on 20th of December. Please use the [Pentabarf](https://penta.fosdem.org/submission/FOSDEM21/) system to submit a talk proposal for the devroom. On the "General" tab, please look for the "Track" option and choose "Real Time Communications devroom". ### First-time speaking? FOSDEM devrooms are a welcoming environment for people who have never given a talk before. Please feel free to contact the devroom administrators personally if you would like to ask any questions about it. This year this is more true than ever, being able to record your presentation offline without an audience in front can greatly help build up one's confidence! ### Submission guidelines The Pentabarf system will ask for many of the essential details. Please remember to re-use your account from previous years if you have one. In the "Submission notes", please tell us about: - The purpose of your talk - Any other talk applications (devrooms, lightning talks, main track) - Availability constraints and special needs You can use HTML and links in your bio, abstract and description. If you maintain a blog, please consider providing us with the URL of a feed with posts tagged for your RTC-related work. We will be looking for relevance to the conference and devroom themes, presentations aimed at developers of free and open source software about RTC-related topics. Please feel free to suggest a duration between 20 minutes and 55 minutes but note that the final decision on talk durations will be made by the devroom administrators based on the number of received proposals. As the two previous devrooms have been combined into one, we may decide to give shorter slots than in previous years so that more speakers can participate. Please note FOSDEM aims to record and live-stream all talks. The CC-BY license is used. ### Recording help The devroom organization is able to provide help with recording your session. The recording would be performed at a scheduled time with one of us, so you won't be alone giving your presentation. Minimal edits will be possible, but the ideal plan is to record it in one shot. Thanks Dan Jenkins for providing us with the means to do this! Volunteers needed ----------------- To make the devroom run successfully, we are looking for volunteers. This year many things be done for the first time, so all the help we can get is more than welcome. Spread the word and discuss --------------------------- If you know of any mailing lists where this CfP would be relevant, please forward this document. If this devroom excites you, please blog or microblog about it, especially if you are submitting a talk. If you regularly blog about RTC topics, please send details about your blog to the planet site administrators: - All projects https://planet.freertc.org planet(a)freertc.org - XMPP https://planet.jabber.org ralphm(a)ik.nu - SIP https://planet.sip5060.net planet(a)sip5060.net Please also link to the Planet sites from your own blog or web site as this helps everybody in the free real-time communications community. Contact ------- For any private queries, contact us directly using the address **fosdem-rtc-admin(a)freertc.org** and for any other queries please ask on the [Free-RTC mailing list](http://lists.freertc.org/mailman/listinfo/discuss).

MID-Registrar Example
by moisesynfante 23 Dec '20

23 Dec '20

Hello, I'm a newbie when it comes to Kamailio and I would like to know if there's a working example of a Mid-Registrar implementation. I read on other posts that the UAC module can be used to achieve this but, honestly, I don't understand how. If any of you could provide some path I could follow I would be very thankful. -- Sent from: http://sip-router.1086192.n5.nabble.com/Users-f3.html

Re: [SR-Users] DLGLOAD stuck in Dispatcher Module(HA Mode)
by harneet singh 22 Dec '20

22 Dec '20

Apologies for not having included the sr-users in the previous email. Anyhow, the solution suggested by Social Boh indeed worked, as a side effect of which we would not run into the issue described. *NOTE:* There was a peculiar configuration in keepalived with keeping both the nodes as BACKUP and setting the 'nopreempt' flag only in the actual MASTER(one with higher 'priority') side to make the keepalived thing to work properly.

send MESSAGE to other sessions of same user
by Syed Shahryar 21 Dec '20

21 Dec '20

What's the best way of sending a message to all other sessions (and the receiver) of the same sender? For example: If user1(a)example.com is logged in to Kamailio from multiple devices and from one of the devices user1 sends a SIP message to user2(a)example.com. I want the message forwarded not only to user2(a)example.com but also to all other user1(a)example.com sessions. What's the easiest way to achieve this? -- -- This message contains confidential information and is intended only for the individual named.

Kamailio proxy b check again IP auth and sends invite request to asterisk with CSeq: 102 INVITE 4 asterisk response with 401 Unauthorized with CSeq: 102 5. Kamailio proxy b sends ACK request with CSeq: 102 ACK 6. Kamailio proxy b sends INVITE request with CSeq: 103 INVITE 7. Asterisk sends 100 trying and 180 ringing with CSeq: 103 INVITE 8.

DLGLOAD stuck in Dispatcher Module(HA Mode)
by harneet singh 16 Dec '20

16 Dec '20

Hi All, I am using Kamailio in HA mode with Keepalived providing the VIP(Virtual IP) functionality, and have run into a rather peculiar issue. *Setup:* Caller ------------ KamailioVIP(*Primary *and *Secondary* Kamailio)------- Callee HA provided by Keepalived DMQ is used between the Primary and Secondary Kamailio for dialog sync *Issue Seen:* *Suppose the Primary Kamailio has been brought down* and the Secondary one is actually active and tied to the VIP. When a call is fired from the Caller, it traverses through the Secondary Kamailio and lands onto the callee. The dialogs are updated properly. At this point, the Primary Kamailio is brought up, and dialog state is synced due to the DMQ module. The Keepalived will now attach the VIP to the Primary Instance. If the caller hangs up the phone at this point, the BYE sip message traverses through the Primary Kamailio instance to the callee and the call is cleared, but there are two issues here. 1. The Primary Kamailio throws an error in *ds_load_remove() *saying that it cannot find the load for the specific call id. This is apparently due to the fact that the dispatcher data is not synced between the two modules but dialog data is. So dialog wise, things are fine. Can this be fixed somehow? 2. The above is still as grave a problem as the dialogs are cleared. BUT, if we check the '*kamcmd dispatcher.list*' on the *SECONDARY* kamailio even well after the call is cleared, the *DLGLOAD* shows 1. Since we are using the *Call Load based distribution* for the dispatching, this is effectively one call stuck on the dispatcher, which leads to resource leak. Is this a known issue, and if so, do we have a way to circumvent this?

Is this the best approach? I've restarted my Kamailio but i don't see any ping going to my BD. Is there any other config that I need to add so that the pings are sent? Is it possible to do a ping to verify connection and reconnect mannualy on the config file? Best Regards,

Wrong To tag in t_reply
by Ivan Ribakov 14 Dec '20

14 Dec '20

Hi all, I’m trying to implement following routing behaviour: - ingress INVITE is sequentially forked to 1 or more endpoints - under certain conditions sequential forking may be stopped and pre-defined error returned to the caller Here’s is part of the config responsible for handling errors: failure_route[ROUTE_ELEMENT_FINAL_FAILURE_HELPER] { route(ROUTE_ELEMENT_FINAL_FAILURE); } route[ROUTE_ELEMENT_FINAL_FAILURE] { # We need to check if the error happens before the first egress, because T-state is not defined yet so we can not use t_reply if ($var(before_first_egress) == 0) { t_reply("$var(sipCode)", "$var(sipMessage)"); } else { sl_send_reply("$var(sipCode)", "$var(sipMessage)"); } } Here is a simple scenario where delivering call to first endpoint times out after receiving 180 Ringing (using custom fr_inv_timer value) where: - .33 is caller - .208 is Kamailio - .138 is callee Notice that 504 is retransmitted by Kamailio. Here is a comparison of 180 and 504 returned by Kamailio: As can be seen, 180 was proxied from the callee and has callee’s to-tag (tag=CALLEE1), however 504 that was generated by Kamailio using t_reply() has a different to-tag (presumably generated by Kamailio). How can I tell Kamailio not to generate new to-tag but to use the last one that proxied back to the caller? Thanks in advance for any help! Regards, Ivan

how to use environment variables to set listen address

This is a generic question about using environment variables in a config file. If I want to use below where TLS_IP itself is a constant defined somewhere else. TLS_IP might be set via an env variable as well. #!define TLS_TO_LISTEN tls:TLS_IP:$env(TLS_PORT) Will that work? I see syntax errors and other weird issues.

empty body on first NOTIFY on REGINFO subscription - bug ?
by Adrian Tabacioiu 11 Dec '20

11 Dec '20

Hello, If the user never registered (or few hours passed from its unregister) the subscription to REGINFO will return an empty body NOTIFY (no xml). I don't see any flag in module to force a body for this case, as in the presence module is force_dummy_presence who can force a body on a first NOTIFY. The RFC3680 says : o Notifications triggered from a SUBSCRIBE contain full state (the list of all contacts bound to the address-of-record). It appears that in this case the response is not conform to RFC. Regards, Adrian

porting keepalive module new functions on 5.4 on 5.3?
by Benoit Chesneau 11 Dec '20

11 Dec '20

2 new functions have been added to the keepalive module: - [ka_add_destination(sip_uri, owner)](https://kamailio.org/docs/modules/5.4.x/modules/keepalive.html#keep…) - [ka_del_destination(sip_uri, owner)](https://kamailio.org/docs/modules/5.4.x/modules/keepalive.html#keep…) Is there any possibility to do the same on 5.3? It seems that on 5.3 adding a destination can only be done statically: https://kamailio.org/docs/modules/5.3.x/modules/keepalive.html#idm53 or can it also be done dynamically when receiving an event using the kazoo module for example?

Dispatcher algorithm 11 possible priority drifting
by Володимир Іванець 10 Dec '20

10 Dec '20

Hello all! We are running Kamailio version 5.3.3 with 16 small Asterisk servers. Kamailio uses a dispatcher module to distribute calls. Algorithm #11 is selected. All destinations are configured with priority set to 50 and attribute to rweight=50. We noticed that one server constantly receives more calls than others. I run a few tests. I was sending 1000 calls to the system. 4 per second. All servers except one were getting around 60 calls while the last one - around 100. I then noticed that the server which receives most calls is always last in the "kamcmd dispatcher.list" command output. I then changed the order in the dispatcher DB table and repeat the test. The other server that now was last was getting the most calls. Does anyone else use algorithm #11 and finds the same thing? Is there something additional that I can provide to help with the investigation? Thanks!

Re: [SR-Users] Dialog profile not defined
by Gertjan Wolzak 10 Dec '20

10 Dec '20

Hello Kamailions, Well, I think I found the cause of my issue where the Dialog profile was not defined.. Well it was. I had not enabled antiflood, by not enabling antiflood, the htable module was also not loaded... I guess the us of profiles_with_value parameter needs htable? Is that correct? If so, that means the htable is a dependency for the dialog module...., then it would be sometihng that could be added to the documentation of the dialog module. When this is not the case, then I have to dig deeper, as I do not get an error anymore about the profile not being known... Thank you. Gertjan

NAT problem with recvonly calls
by David Cunningham 10 Dec '20

10 Dec '20

Hello, We have a problem with a SIP doorbell device which sends media one way only, and NAT at the receiving device. When the doorbell button is pressed it makes a call to a configured destination. Since the doorbell only sends and doesn't receive it sends the INVITE with sendonly in the SDP, and the destination then replies with a 200 OK with recvonly in the SDP. The problem is that the destination is behind NAT, and its reply contains a private network IP in the SDP. Normally Asterisk when nat=yes works around that by adjusting the destination for RTP to be the address it actually receives audio from, however because this device is recvonly Asterisk never receives audio from it. This means Asterisk keeps trying to send the doorbell's RTP to the private network IP which of course fails, and the destination never gets the RTP from the doorbell. We haven't found a solution in Asterisk to this, so are now looking to Kamailio which acts as a load-balancing proxy in front of Asterisk for one. For example, maybe we could use fix_nated_sdp, but only on 200 OK's with recvonly. Has anyone else encountered this, and are there any recommended solutions?

Re: [SR-Users] NAT problem with recvonly calls

The doorbell is the caller. ICE support would be required on the callee side (between NATed callee and asterisk). There's no need for ICE support on the doorbell/caller side. -ovidiu On Wed, Dec 9, 2020 at 2:42 AM Alex Balashov <abalashov(a)evaristesys.com> wrote: > > ICE support just doesn't seem to me to be something a SIP doorbell would > have. > > On 12/9/20 2:39 AM, Olle E.

Re: [SR-Users] Dialog profile not defined
by Gertjan Wolzak 06 Dec '20

06 Dec '20

Thank you Joel for the tip. But that is also not it..... I tried of course, but when you look at the Dialog module documentation is says: modparam("dialog", "profiles_with_value", "caller ; my_profile") So there are spaces in the modparam config for the dialog profiles. Its just so strange that when starting Kamailio I get the error that the Profile outbound is not configured, while it is... Log line: Dec 6 15:04:04 proxy01 /usr/local/sbin/kamailio[76664]: CRITICAL: dialog [dialog.c:391]: fixup_profile(): profile <inbound> not defined kamailo.cfg # ---- Dialog params ------------- modparam("dialog", "default_timeout", 7200) modparam("dialog", "db_mode", 0) modparam("dialog", "dlg_flag", DLG_FLAG) modparam("dialog", "hash_size", 4096) #modparam("dialog", "detect_spirals", 1) modparam("dialog", "profiles_with_value", "inbound") Im starting to think that I am missing some configuration in the kamailio.cfg file...

Re: [SR-Users] Dialog profile not defined
by Gertjan Wolzak 05 Dec '20

Thanks again Sergiu, /Hmmm... if dialog params are wrapped in a ifdef condition, then do you have something like #!define WITH_DIALOG at the top?/ But the #!define WITH_DIALOG is to choose between loading module parameters or not loading module parameters... When you do not add #!ifdef WITH_XXX before the parameters and #!endif after, then those parameters will be loaded when starting Kamailio. So, I still have the issue that the profile is not being loaded. I have tried renaming the profiles, in the route and the parameters, but that does not make a difference.. # ---- Dialog params ------------- modparam("dialog", "default_timeout", 7200) modparam("dialog", "db_mode", 0) modparam("dialog", "dlg_flag", DLG_FLAG) modparam("dialog", "hash_size", 4096) #modparam("dialog", "detect_spirals", 1) modparam("dialog", "profiles_with_value", "inbound ; outbound") route[CONCURRENT_IN] { #Add call to customer profile #Check if customer has not reached inbound call limit #Get max concurrent calls sql_query("cc", "select max_calls_in from calllimit where cust_id='$avp(custid)'", "ra"); $avp(maxcalls)=$dbr(ra=>[0,0]); sql_result_free("ra"); $avp(concurrent) = 0; get_profile_size("inbound", "$avp(custid)", "$avp(concurrent)"); if( $avp(concurrent) >= $var(max) ) { xlog("L_INFO"," Call limit reached for customer $avp(custid)\r\n "); sl_send_reply("503", "No Lines Available"); exit; } set_dlg_profile("inbound", "$avp(custid)"); return; } But this still results in: Dec 5 09:34:33 proxy01 /usr/local/sbin/kamailio[75755]: CRITICAL: dialog [dialog.c:391]: fixup_profile(): profile <inbound> not defined Dec 5 09:34:33 proxy01 /usr/local/sbin/kamailio[75755]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-6) at cfg:/usr/local/etc/kamailio/kamailio.cfg:1578

question regarding rtpengine and ICE candidate selection
by Andrew Chen 04 Dec '20

04 Dec '20

Hi all, I was wondering if someone can help me understand how the ICE parameter works in the rtpengine module works. So basically our client does an ICE candidate lookup and grabs a list of them and applies it to the INVITE that gets sent to the Kamailio. The list looks like this: 2020-12-03T18:05:46.456030+00:00 ashmainkama51 kamailio[22147]: a=candidate:3373280875 1 udp 2122262783 2001:8a0:78fc:7000:e1d7:e93:3c50:ee71 59827 typ host generation 0 network-id 2 network-cost 10 2020-12-03T18:05:46.456057+00:00 ashmainkama51 kamailio[22147]: a=candidate:3040609428 1 udp 2122197247 2001:8a0:78fc:7000:d979:bf75:dbc0:69f 59828 typ host generation 0 network-id 3 network-cost 10 2020-12-03T18:05:46.456081+00:00 ashmainkama51 kamailio[22147]: a=candidate:1681997092 1 udp 2122129151 192.168.1.66 59829 typ host generation 0 network-id 1 network-cost 10 2020-12-03T18:05:46.456106+00:00 ashmainkama51 kamailio[22147]: a=candidate:2274611867 1 tcp 1518283007 2001:8a0:78fc:7000:e1d7:e93:3c50:ee71 9 typ host tcptype active generation 0 network-id 2 network-cost 10 2020-12-03T18:05:46.456131+00:00 ashmainkama51 kamailio[22147]: a=candidate:4223662180 1 tcp 1518217471 2001:8a0:78fc:7000:d979:bf75:dbc0:69f 9 typ host tcptype active generation 0 network-id 3 network-cost 10 2020-12-03T18:05:46.456155+00:00 ashmainkama51 kamailio[22147]: a=candidate:717406676 1 tcp 1518149375 192.168.1.66 9 typ host tcptype active generation 0 network-id 1 network-cost 10 2020-12-03T18:05:46.456180+00:00 ashmainkama51 kamailio[22147]: a=candidate:2130547417 1 udp 8199935 206.81.191.27 61165 typ relay raddr 85.247.0.121 rport 53091 generation 0 network-id 1 network-cost 10 In the rtpengine_offer, I have this: rtpengine_offer("ICE=force DTLS=passive replace-session-connection replace-origin external internal"); What i am trying to do is to tell the freeswitch endpoint to use rtpengine as ICE candidate and I see in the SDP this is happening: a=candidate:6296910676 1 udp 659136 206.81.191.52 52766 typ host generation 0 Btw..206.81.191.52 is a separate AWS instance running rtpengine binary.

Hello Sergiu, Thank you for the pointer, the line 1576 is: get_profile_size("callee", "$avp(custid)", "$avp(concurrent)"); That is where Kamailio refuses to start....

presence not work proper with subs_db_mode = 2
by Aatif Shaikh 04 Dec '20

04 Dec '20

Hello, all have a problem with Kamailio presence, I have configured my kamailio.cfg to handle dialog presence and facing issue in case of subs_db_mode = 2 in case of mode 2 facing the following presence issue. 1. after hangup presence is still up 2. sometimes stuck in a ringing state 3. sometimes presence not came..etc but in the case of subs_db_mode = 3 (DB ONLY) mode presence working fine not facing any issue with this mode. I noticed that sometimes Kamailio will throw the following message during PUBLISH processing and it will not generate appropriate NOTIFY I also verify inactive watcher subscription is there for that user and also a proper entry in the dialog table. MSG during PUBLISH processesing and it will not generate appropriate NOTIFY Oct 30 07:42:10 NC-HOSTED-1 /usr/local/sbin/kamailio[2409]: DEBUG: presence [notify.c:1444]: publ_notify(): Could not find subs_dialog kamailio.cfg param modparam("pua", "db_url", DBURL_KAMAILIO) modparam("pua", "db_mode", 2) modparam("pua", "update_period", 100) modparam("pua", "dlginfo_increase_version", 1) modparam("pua", "default_expires", 3600) modparam("pua", "fetch_rows", 1000) modparam("pua", "outbound_proxy", SERVER_IP) modparam("dialog", "db_url", DBURL_KAMAILIO ) modparam("dialog", "db_mode", 1) modparam("dialog", "db_update_period", 260) modparam("dialog", "db_fetch_rows", 500) modparam("pua_dialoginfo", "include_callid", 1) modparam("pua_dialoginfo", "send_publish_flag", 8) modparam("pua_dialoginfo", "caller_confirmed", 0) modparam("pua_dialoginfo", "include_tags", 1) modparam("pua_dialoginfo", "use_pubruri_avps", 1) modparam("pua_dialoginfo", "include_localremote", 1) modparam("pua_dialoginfo", "override_lifetime", 300) modparam("pua_dialoginfo", "pubruri_caller_avp", "$avp(s:puburis_caller)") modparam("pua_dialoginfo", "pubruri_caller_dlg_var", "pubruri_caller") modparam("pua_dialoginfo", "pubruri_callee_dlg_var", "pubruri_callee") modparam("pua_dialoginfo", "pubruri_callee_avp", "$avp(s:puburis_callee)") modparam("presence_dialoginfo", "force_single_dialog", 1) modparam("presence", "db_table_lock_type", 0) modparam("presence", "db_url", DBURL_KAMAILIO) modparam("presence", "db_update_period", 5) modparam("presence", "send_fast_notify", 1) modparam("presence", "clean_period", 100) modparam("presence", "subs_db_mode", 2) //modparam("presence", "subs_db_mode", 3) modparam("presence", "timeout_rm_subs", 1) //new/ //modparam("presence", "notifier_processes", 2) //new// modparam("presence", "notifier_poll_rate", 20) //new// modparam("presence", "waitn_time",1) modparam("presence", "fetch_rows", 1000) modparam("presence", "presentity_table", "presentity") modparam("presence", "active_watchers_table", "active_watchers") modparam("presence", "watchers_table", "watchers") modparam("presence", "max_expires", 3600) modparam("presence_xml", "db_url", DBURL_KAMAILIO) modparam("presence_xml", "force_active", 1) logic for presence request_route { if(is_method("PUBLISH") || is_method("SUBSCRIBE")) { route(HANDLE_PRESENCE); } } route[HANDLE_PRESENCE] { if (! t_newtran()) { sl_reply_error(); exit; } if(is_method("PUBLISH")) { handle_publish(); t_release(); } else if( is_method("SUBSCRIBE")) { handle_subscribe(); t_release(); } exit; } route[RELAY] { if(is_method("INVITE|BYE|UPDATE|CANCEL|ACK")) { $avp(t_ext) = $tU ; $avp(domain) = $fd ; $avp(et) = $_s(sip:$avp(t_ext)@$avp(domain)) ; $avp(s:puburis_callee) = $avp(et); setflag(8); dlg_manage(); } } I already report this issue in Kamailio git https://github.com/kamailio/kamailio/issues/2540 -- -- Regards, *Aatif Shaikh *| Software Developer +91 9033976268Hangout: aatif.shaikh(a)ecosmob.comSkype : aatif.shaikh(a)ecosmob.com *Ecosmob Technologies Pvt.

Dialog profile not defined
by Gertjan Wolzak 03 Dec '20

03 Dec '20

Hello Kamailions, I am running into the following issue. The same setup I had working on 5.0, now I am using a 5.4 version of Kamailio, but I do not believe it has to do with the version, more with my ability to make errors... I am trying to limit incoming calls by using the dialog module. The max concurrent calls value I retrieve from a database. But when I try to start Kamailio it will not because the dialog profile is not defined... These are my configured Dialog parameters: # ---- Dialog params ------------- modparam("dialog", "default_timeout", 7200) modparam("dialog", "db_mode", 0) modparam("dialog", "dlg_flag", DLG_FLAG) modparam("dialog", "hash_size", 4096) #modparam("dialog", "detect_spirals", 1) modparam("dialog", "profiles_with_value", "callee") My check on the concurrent inbound calls: route[CONCURRENT_IN] { #Add call to callee profile #Check if callee has not reached inbound call limit #Get max concurrent calls sql_query("cc", "select max_calls_in from calllimit where cust_id='$avp(custid)'", "ra"); $avp(maxcalls)=$dbr(ra=>[0,0]); sql_result_free("ra"); $avp(concurrent) = 0; get_profile_size("callee", "$avp(custid)", "$avp(concurrent)"); if( $avp(concurrent) = $var(max) ) { xlog("L_INFO"," Call limit reached for customer $avp(custid)\r\n "); sl_send_reply("503", "No Lines Available"); exit; } set_dlg_profile("callee", "$avp(custid)"); return; } And the kamailio log error: Dec 3 09:12:08 proxy01 kamailio[74102]: INFO: <core> [main.c:2833]: main(): processes (at least): 21 - shm size: 67108864 - pkg size: 8388608 Dec 3 09:12:08 proxy01 kamailio[74102]: CRITICAL: dialog [dialog.c:391]: fixup_profile(): profile <callee> not defined Dec 3 09:12:08 proxy01 kamailio[74102]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-6) at cfg:/usr/local/etc/kamailio/kamailio.cfg:1576 Is someone able to see where I go wrong and point me in the right direction?

$TF pseudo variable can not be used
by Володимир Іванець 03 Dec '20

03 Dec '20

Hello! I'm using a $TF variable in my config for some logging purposes. It was providing the correct string with Kamailio version 5.3.8 on CentOS 6 and 8. After updating to Kamailio version 5.4.1, the variable started to show something else. I also tried versions 5.4.2 and development 5.5.0 on CentOS 6 and the problem still persists. With version 5.5.0_dev3 this variable shows "pG▒" for me. I was wondering if someone else is using it too with Kamailio version 5.4.1 or newer on different platforms and has this issue. Thanks!

kamailio not absorbing ACK to CANCEL when behind a Path proxy
by Anthony Alba 02 Dec '20

02 Dec '20

Folks, I have a weird situation, when I enable Path header, kamailio behind a Path proxy, that kamailio doesn't recognise the ACK to CANCEL and tries to forward it. Test scenario: - voice.example.com is a stateless proxy with TLS/UDP bridging to kamailio. - on the UDP leg to kamailio it will add a Path: header to REGISTER UA1 = david is calling UA2 = charles and UA2 is sending 603 1 . UA1: preloaded route set (outbound proxy) # this is the Path proxy Route: sip:voice.example.com;transport=tls;lr 2. UA2: sends CANCEL 603 - kamailio immediately sends its (per-hop?) ACK - kamailio forwards CANCEL to UA1 kamailio sent this (per-hop?) ACK - the Route header is the internal UDP interface of the Path proxy ACK sip:charles@192.168.1.7:37309;transport=TCP;ob SIP/2.0 Via: SIP/2.0/UDP 192.168.122.99:5064;branch=z9hG4bK735d.6b27c8d09e40462ef47eccf90eb10823.0 Max-Forwards: 70 From: sip:david@voice.example.com;tag=i1acAHsitf2gcN9uHH-ZSyJ5OdT8O5M0 To: <sip:charles@voice.example.com>;tag=LmUY79rIdBQiiSakML4F0lHl271VdUn8 Call-ID: qM3W-fMrzPsvcjRSD1okEp5nbgHCF5Hu CSeq: 16667 ACK Route: <sip:192.168.122.100;lr> Content-Length: 0 3. UA1 sends ACK kamailio sees this - top Via is path proxy - 2nd Via is UA (caller) - CSeq correctly matches the INVITE - kamailio does not recognise this ACK from UA1(caller), tries to forward it, and also resends 603 to UA1(caller) 3 times ACK sip:charles@voice.example.com SIP/2.0 Via: SIP/2.0/UDP 192.168.122.100:5060;branch=z9hG4bKb3c9a7a3b6ec9e78d0144cda709f7047 Via: SIP/2.0/TLS 192.168.1.17:44925;rport=44925;branch=z9hG4bKPjFM-9gpaJEghJvN19TjnvScCwCoAGzwEc;alias;received=192.168.1.17 Max-Forwards: 70 From: sip:david@voice.example.com;tag=i1acAHsitf2gcN9uHH-ZSyJ5OdT8O5M0 To: sip:charles@voice.example.com;tag=LmUY79rIdBQiiSakML4F0lHl271VdUn8 Call-ID: qM3W-fMrzPsvcjRSD1okEp5nbgHCF5Hu CSeq: 16667 ACK Route: <sip:voice.example.com;transport=tls;lr> Content-Length: 0 Now kamailio should absorb this ACK, as it has already sent its per-hop ACK. Instead I see ERROR: <core> [core/forward.c:541]: forward_request(): cannot forward to af 2, proto 3 no corresponding listening socket I don't expect kamailio to forward anything at this point. The route block is route[WITHINDLG] and it calls t_relay() normally. route[WITHINDLG] { if (!has_totag()) return; # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { route(DLGURI); if (is_method("BYE")) { setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails } else if ( is_method("ACK") ) { # ACK is forwarded statelessly route(NATMANAGE); } else if ( is_method("NOTIFY") ) { # Add Record-Route for in-dialog NOTIFY as per RFC 6665. record_route(); } route(RELAY); # we should absorb this ACK, no? exit; } 4. If I remove the Path proxy and kamailio is the TLS proxy at voice.example.com the call flow works perfectly. The ACK from caller (david) is absorbed. 5. Regular calls, when UA2 accepts the call, work fine. In-dialog requests for BYE, from both UAs, work correctly with this Path proxy. Each UA has the complete 5 element route set( 2 x Path proxy + kamailio + 2 x Path proxy). The working route set looks like this: BYE sip:david@192.168.1.17:44925;transport=TCP;ob SIP/2.0 Via: SIP/2.0/TLS 192.168.1.7:37309;rport;branch=z9hG4bKPjHdUtaUL5AfRcV-SX1Puya4niJKOOQ4VQ;alias Max-Forwards: 70 From: <sip:charles@voice.example.com>;tag=6zOt.H7w8NL5njV7klwGLlSJy.U5yBC9 To: <sip:david@voice.example.com>;tag=Pa0ORUxA-7lK0BnR4pLJ5n8rn2OvQrJy Call-ID: 3gWy4Q7O.-zQ-I07lRKHyFyX6azyCSwG CSeq: 12855 BYE Route: <sip:voice.example.com;transport=tls;lr;r2=on> Route: <sip:192.168.122.100;lr;r2=on> Route: <sip:192.168.122.99:5064;lr> Route: <sip:192.168.122.100;lr;r2=on> Route: <sip:voice.example.com;transport=tls;lr;r2=on> User-Agent: basesip 1.0.0 Content-Length: 0 Any ideas?

Kamailio 5.4 ndb_redis, selecting a database
by Daniel Donoghue 02 Dec '20

02 Dec '20

Hello, I note that I can use the ndb_redis server config parameter to specify connection details for my redis servers; I also note that the connection string can specify a “db” parameter which can be set from 0 to 9, with the default being 0. I am looking for a way to dynamically set the db parameter. I do not which to add the same server with different names N times just to select a different db and having N times more connections to it than necessary. It looks as though I can call redis_cmd(“svrN”, “SELECT dbN”, “init”); but will that propagate properly and set the correct db for all connections to my redis server for the lifetime of the request? Ideally, I’d like to be able to specify an avp for the db, or have a function to set the db per request. With every blessing, — Daniel Donoghue

How to DIY/Setup An Open Source IP PBX Appliance/Server?
by Turritopsis Dohrnii Teo En Ming 01 Dec '20

01 Dec '20

Subject: How to DIY/Setup An Open Source IP PBX Appliance/Server? Good day from Singapore, After reading recent reviews, I gather that Asterisk is the gold standard when it comes to open source VoIP systems and it is the most famous open source PBX out there. Article: Compare the Top 10 Best Open Source PBX Software of 2020 Link: https://www.voipreview.org/business-voip/best-open-source-pbx-software Article: Top 10 Free Open Source PBX Software Solutions Link: https://getvoip.com/blog/2016/09/23/best-open-source-pbx-software/ The following is an excerpt from Wikipedia: "Asterisk is a core component in many commercial products and open-source projects. Some of the commercial products are hardware and software bundles, for which the manufacturer supports and releases the software with an open-source distribution model. AskoziaPBX, a fork of the m0n0wall project, uses Asterisk PBX software to realize all telephony functions. AstLinux is a "Network Appliance for Communications" open-source software distribution.[15] FreePBX, an open-source graphical user interface, bundles Asterisk as the core of its FreePBX Distro[16] LinuxMCE bundles Asterisk to provide telephony; there is also an embedded version of Asterisk for OpenWrt routers. PBX in a Flash/Incredible PBX and trixbox are software PBXes based on Asterisk. Elastix previously used Asterisk, HylaFAX, Openfire and Postfix to offer PBX, fax, instant messaging and email functions, respectively, before switching to 3CX. Issabel is an open-source Unified Communications software which uses Asterisk for telephony functions. It was forked from the open-source versions of Elastix when 3CX acquired it. *astTECS uses Asterisk in its VoIP and mobile gateways." Link: https://en.wikipedia.org/wiki/Asterisk_(PBX) I would like to DIY/setup an IP PBX appliance/server using free open source projects. Which free open source project, mentioned in the list and links above, would you recommend to DIY my IP PBX appliance/server? Should I buy a desktop computer or get one of those appliances listed in the link below to serve as my IP PBX appliance/server? Link: https://www.lazada.sg/products/pfsense-iron-metal-case-fanless-intel-celero… Please also refer me to very good, detailed and well explained guides/tutorials/manuals on setting up open source IP PBX appliances/servers. Lastly, please recommend a cheap and affordable IP phone (suggest brand and model) to go along with my DIY open source IP PBX appliance/server.

How to msg_apply_changes in a branch route?
by Anthony Alba 01 Dec '20

01 Dec '20

Is there a way to obtain the effect of msg_apply_changes in a branch route? I want to do: route[BRANCHMANAGE] { rtpengine_manage() msg_apply_changes() // further mangle the SDP with textops for // obtuse UAs } The reason for this, is that after forking, I have some UAs that are extremely picky about SDP, and I need to mangle the body to make them happy. (4000 char limit, 68 attribute limit on SDP body - ever seen that? Compared with the absolutely gigantic OFFERs from WebRTC signalling libraries...) Now rtpengine_manage() and textops are working on separate copies of the msg body and the results don't stack correctly. Cheers Anthony Alba

Kamailio behind HAProxy
by Joey Golan 01 Dec '20

01 Dec '20

Hello, I have a kamailio server running behind HAProxy with proxy protocol v2 enabled. In Kamailio I have set the parameter tcp_accept_haproxy=yes and loaded tcpops module. UEs are registered using TLS and kamailio sees that the message has received from their real ip address + port and not HAProxy ip + port. When UE A calls UE B, kamailio is trying to reach UE B using his real ip address and port instead of HAProxy IP address + port. I know I can get the tcp ip and port of HAProxy using $tcp(c_si) and $tcp(c_sp) but I can’t make it work. What is the right way to do this? How should I use these variables properly in order to establish the call successfully? Thanks, Joey.

core dump error when running under docker
by Carlos Vicente 30 Nov '20

30 Nov '20

Greetings, I'm having a "fun" time trying to run Kamailio inside a Docker container. It keeps failing with: 0(238) DEBUG: <core> [core/mem/pkg.c:108]: pkg_print_manager(): pkg - using memory manager: q_malloc 0(238) DEBUG: <core> [core/mem/shm.c:300]: shm_print_manager(): shm - using memory manager: q_malloc Illegal instruction (core dumped) Unfortunately the core dump is nowhere to be found. I have tried to follow the instructions at: https://www.kamailio.org/wiki/tutorials/troubleshooting/coredumpfile but that hasn't helped. The environment is as follows: * Host hardware: Raspberry Pi 4 (4G memory) * Host OS: Ubuntu 20.04.1 LTS * Docker version 19.03.13 * Docker base image: arm32v7/ubuntu root@2ef8a21534fa:/# kamailio -v version: kamailio 5.3.2 (arm/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT-NOSMP, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 9.2.1 The config file passes the syntax check: kamailio -c -f /etc/kamailio/kamailio.cfg and, the most interesting part, if I run Kamailio on the host machine, _with the exact same config file_, it runs fine. I'd appreciate any clues you may have. Thanks. cv

handling of locally generated 478 errors
by Henning Westerholt 27 Nov '20

27 Nov '20

Hello, I want to ask for your opinion on the best approach regarding the handling of locally generated 478 errors. To give an example, like the ones generated from TM during t_relay() on an unresolvable destination. Nov 25 17:40:13 kamailio[19345]: ERROR: {28607414 INVITE bba500ac-a9df-1239-6693-00505682c04d} tm [ut.h:286]: uri2dst2(): failed to resolve "invalid.skalatan.de" :unresolvable A or AAAA request (-7) Nov 25 17:40:13 kamailio[19345]: ERROR: {28607414 INVITE bba500ac-a9df-1239-6693-00505682c04d} tm [t_fwd.c:1738]: t_forward_nonack(): failure to add branches Nov 25 17:40:13 kamailio[19345]: CRITICAL: {28607414 INVITE bba500ac-a9df-1239-6693-00505682c04d} rtpengine [../../core/parser/../ip_addr.h:658]: ip_addr2sbuf(): unknown address family 0 These errors will not show up in onreply or failure_route. A long time ago this was discussed on the list [1], as some functionality were phased out out that support these scenarios. Kamailio will try to generate a 478 with TM, this will obviously fail as well, and then generate a 478 with SL. Question 1) Is this intentional that the internally generated 478 is not showing up in the failure_route, like for for 408? This has been tested several times, but it is a complicated configuration. Question 2) Are there any other (better) ideas how to handle that besides using a "event_route[sl:local-response]" to catch this, e.g. to tear down otherwise stale rtpengine sessions etc..? As a side note, event_route[tm:local-response] seems not to work as well because of the tm failure.

issues using evapi module
by David Escartin 26 Nov '20

26 Nov '20

Dear all We are trying to use the evapi module to send some data to an external application but I'm having problems getting the clients connected. I have the kamailio (version 5.3) running with a tcp socket 127.0.0.1:8228, and the evapi params are just modparam("evapi", "workers", 4) modparam("evapi", "netstring_format", 0) modparam("evapi", "bind_addr", "127.0.0.1:8448") modparam("evapi", "max_clients", 32) I tried a different number of workers and netstring_format 1 too. When I start the kamailio i added some debug to the code, and seems when doing the mod init of the evapi dispatcher 38(4779) DEBUG: <core> [core/sr_module.c:779]: init_mod_child(): idx 38 rank -2: evapi [EvAPI Dispatcher] it reaches to while(1) { ev_loop (loop, 0); } at evapi_run_dispatcher function. I guess if I connected to the tcp socket and sent some event, I would see the client accepted and the event route evapi:connection-new would be triggered. But i'm not able to do that. I tried to use the prime option, a tcp input client connection from logstash, so i could relay the data to the logstash using the evapi relay, but i only see the tcp socket being created but no client accepted. I also tried to connect with an erlang gen_tcp client, but it's the same i only see 47(4798) DEBUG: <core> [core/ip_addr.c:229]: print_ip(): tcpconn_new: new tcp connection: 127.0.0.1 47(4798) DEBUG: <core> [core/tcp_main.c:1174]: tcpconn_new(): on port 54537, type 2, socket 105 47(4798) DEBUG: <core> [core/tcp_main.c:1497]: tcpconn_add(): hashes: 1117:1187:1505, 1 47(4798) DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0xad0880, 105, 2, 0x7fc211712d58), fd_no=53 and if i try to send any data 47(4798) DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0xad0880, 105, -1, 0x0) fd_no=54 called 47(4798) DEBUG: <core> [core/tcp_main.c:4456]: handle_tcpconn_ev(): sending to child, events 1 47(4798) DEBUG: <core> [core/tcp_main.c:4129]: send2child(): selected tcp worker idx:0 proc:43 pid:4791 for activity on [tcp:127.0.0.1:8448], 0x7fc211712d58 43(4791) DEBUG: <core> [core/tcp_read.c:1749]: handle_io(): received n=8 con=0x7fc211712d58, fd=39 43(4791) DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0xb3c720, 39, 2, 0x7fc211712d58), fd_no=1 43(4791) DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0xb3c720, 39, -1, 0x10) fd_no=2 called 43(4791) DEBUG: <core> [core/tcp_read.c:1671]: release_tcpconn(): releasing con 0x7fc211712d58, state 1, fd=39, id=1 ([127.0.0.1]:54537 -> [127.0.0.1]:8448) 43(4791) DEBUG: <core> [core/tcp_read.c:1672]: release_tcpconn(): extra_data (nil) 47(4798) DEBUG: <core> [core/tcp_main.c:3559]: handle_tcp_child(): reader response= 7fc211712d58, 1 from 0 47(4798) DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0xad0880, 105, 2, 0x7fc211712d58), fd_no=53 47(4798) DEBUG: <core> [core/tcp_main.c:3686]: handle_tcp_child(): CONN_RELEASE 0x7fc211712d58 refcnt= 1 and when i try to send any data 38(10867) DEBUG: evapi [evapi_dispatch.c:610]: evapi_recv_notify(): received [0x7f17d23fc628] [{"test" : "1.1.1.1", "uuid" : "1-31629(a)3.3.3.3" , "pdd" : "4"}] (75) 38(10867) DEBUG: evapi [evapi_dispatch.c:316]: evapi_dispatch_notify(): the message was sent to 0 clients I don't know what i'm missing, or if i'm understanding the use of the module correctly could you please take a look? thanks a lot David -- [image: Logo] David Escartín Almudévar VoIP/Switch Engineer descartin(a)sonoc.io *SONOC* C/ Josefa Amar y Borbón, 10, 4ª · 50001 Zaragoza, España Tlf: +34 917019888 · www.sonoc.io

Location Fields Address vs Received
by Daniel Greenwald 25 Nov '20

25 Nov '20

On a usrloc record there is an Address field and Received field. The Received field is sometimes not set. What causes it to be not set and what is the difference between the two fields. Sorry if this is a dumb question, I looked at documentation but couldn't find it spelled out. Here is are 2 examples from kamcmd ul.dump: { AoR: utkcf9b6h3(a)ata.phaxio.com Contacts: { Contact: { Address: sip:utkc4ff9b6h3@69.78.34.56:4615;transport=tcp Expires: 42 Q: -1.000000 Call-ID: d1c314305df3d342(a)192.168.0.3 CSeq: 129173 User-Agent: OBIHAI/OBi200-3.2.2.5898 Received: [not set] Path: [not set] State: CS_NEW Flags: 0 CFlags: 0 Socket: tcp:10.0.22.254:5060 Methods: 7839 Ruid: uloc-5fbdd369-491e-4 Instance: <urn:uuid:00000000-0000-0000-0000-9cadef62b3da> Reg-Id: 0 Server-Id: 0 Tcpconn-Id: 58 Keepalive: 0 Last-Keepalive: 1606317577 Last-Modified: 1606317577 } } } Contact: { Address: sip:mfjngfd272av@192.168.0.106:5060 Expires: 30 Q: -1.000000 Call-ID: 67413de375b2e76c(a)192.168.0.106 CSeq: 146320 User-Agent: OBIHAI/OBi300-3.2.2.5921 Received: sip:70.34.56.78:5060 Path: [not set] State: CS_NEW Flags: 0 CFlags: 64 Socket: udp:10.0.22.254:5060 Methods: 7839 Ruid: uloc-5fbdd369-490e-efa3 Instance: <urn:uuid:00000000-0000-0000-0000-9cadef810877> Reg-Id: 0 Server-Id: 0 Tcpconn-Id: -1 Keepalive: 1 Last-Keepalive: 1606314719 Last-Modified: 1606314719 }

Next online devel meeting - Wed, Nov 25, 2020, 15:00UTC
by Daniel-Constantin Mierla 25 Nov '20

25 Nov '20

Hello, in order to plan the roadmap to next major release, it is time to organize another online devel meeting, so the developers and community members can syncronize and plan what should be done till Kamailio v5.5 will be out. Because freenode.net service is requiring user registration to join IRC channels on their servers, the meeting will be done on a matrix chat room. More details are in the wiki page of the event, available at: * https://www.kamailio.org/wiki/devel/irc-meetings/2020b Feel free to add there topics that you want to be discussed. The proposed date is next Wednesday, November 25, 2020, at 15:00UTC (15:00 London/Dublin, 16:00 most of West Europe, 10:00 New York), but other dates can be proposed if they suit for more participants.

How to route to calls to asterisk
by Mihai Cezar 23 Nov '20

23 Nov '20

Hi all, I need some help on getting to work my scenario: I have 3 asterisk servers, and every agents (soft phones like zoiper) is connecting to which server they need by contacting the PublicIP of each server. (the problem is that I need to reuse the IP address on others servers) . I want if is possible to use a proxy like "haproxy" but for sip to redirect the agents (softphones), to their coresponding server. For example: - james(a)ast.example.com -> must register to asterisk server 1, - sarah(a)ast2.exampe.com -> must register to asterisk server 2 - andy(a)ast3.example.com-> must register to asterisk server 3 ast.example.com, ast2.example.com, ast3.example.com = will share all the same ip, when the request arrives in the proxy it should check the vhost and redirect to the coresponding server for registering. Any hints and how to do this scenario?

Hello kamailioers, Version 5.4.2. I have a R-URI that I need to change TLS -> TCP in all branches. I do this in request route before t_relay: // AoR has multiple contacts, all with transport=TLS route[REQUEST] { textops.subst_uri("/transport=TLS/transport=TCP/i") //parallel forking //why doesn't this change all branches? t_relay() } If I print out the R-URI in the branch route, I see that only the first R-URI is changed, in the other branches the R-URI transport=TLS is not changed to transport=TCP. Any suggestions on how to get this to work across all Contact addresses? Thanks Anthony Alba

Issue with ca-list
by George Goglidze 20 Nov '20

20 Nov '20

Hi Folks, I was wondering if somebody could help me with an issue. I’m a newbie here, just installing Kamailio sip server. I’ve enabled TLS, and am trying create a SIP Trunk to external SIP Service which is TLS enabled port 5061. I’ve configured the following in tls.cfg: [server:default] method = TLSv1.2+ verify_certificate = yes require_certificate = yes private_key = /etc/kamailio/certs/sbc-private.pem certificate = /etc/kamailio/certs/godaddy.pem ca_list = /etc/kamailio/certs/calist.pem In the section above – ca_list = calist.pem contains all the CA’s and Subordinates of the destination server. Private_key and certificate are of my own server (public godaddy signed) [client:default] method = TLSv1.2+ verify_certificate = yes require_certificate = yes private_key = /etc/kamailio/certs/sbc-private.pem certificate = /etc/kamailio/certs/godaddy.pem ca_list = /etc/kamailio/certs/godaddyca.pem In the section above the ca_list is godaddy’s ca and subordinate. In the wireshark I can see that I’m sending out SIP OPTIONS PING (I’m using dispatcher module). Then the server replies with tls SERVER HELLO which includes it’s certificate But for some reason we are rejecting it: Alert (level: fatal, Description: Unknown CA) How should I set this up to make sure the remote server CA’s are verified? Thank you,

t_uac_send function with From tag
by João Vitor Arruda 20 Nov '20

20 Nov '20

Hello, I'm trying to use the function t_uac_send inside a failure_route as described in https://kamailio.org/docs/modules/5.3.x/modules/tm.html#tm.f.t_uac_send to send a CANCEL out. Although the documentation says "it can include From/To tags" i was not able to get the from tag provided to be used. Another random generated one is used. I've tried the following format without success: t_uac_send("CANCEL", "$ru", "", "", "From: <$fu>;tag=$ft\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") t_uac_send("CANCEL", "$ru", "", "", "From: $fu;tag=$ft\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") t_uac_send("CANCEL", "$ru", "", "", "From: bob(a)kamailio.org;tag=2w3e\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") In the last one which is copied from the documentation that is how the >From header going out looks like: From: <bob(a)kamailio.org;tag=2w3e>;tag=3393f0703fb0ccaca74109ff37de39f5-36d71ef0 Any tips on how to get the From tag passed to the function to be used? Thanks, Joao Arruda

Kamailio suddenly stopes responding to sip messages
by Uttam Giri 19 Nov '20

19 Nov '20

Hi, We are using Kamailio with Jitsi client where we observed sometimes Kamailio stops responding to sip messages. As a result, my Jitsi client goes offline and never back online. Also in the Kamailio syslog there are no error logs(debug enabled) related to this issue. As a temporary workaround, we had to restart the Kamailio server all the time. Does anyone observed a similar issue and can suggest any resolution.

Add Reason Header to kamailio generated CANCEL
by Alfonso Pinto 18 Nov '20

18 Nov '20

Hi everyone, I've got a specific case: when the inv_fr times out, I need to add a Reason header to the CANCEL generated by kamailio. I've tried to see if I could do it in the onsend_route, but that one is not triggered for the generated CANCEL. I also checked event_route[tm:local-request], but that one isn't triggered either for the generated CANCEL. Is there any way to do it? Or maybe to have any pointer about where to look in the code so I may try to trigger event_route[tm:local-request] for these generated CANCELs? Regards, Alfonso

record-route and INFO
by David Villasmil 18 Nov '20

18 Nov '20

Hello guys, I have a setup like this: FS(private)-->(private)Kamailio1(Public)-->Kamailio2(public)-->provider. I have mhomed=0, enable_double_rr=1, I'm listening on 2 different ports, 1 private, 1 public (with advertise) and on Kamailio1 the DISPATCH ROUTE I force the socket $fs = "LISTEN_PRIVATE_PROTO:LISTEN_PRIVATE_IF:5080"; To the private ip when the destination IP is a private IP. This all works fine. But When calling OUT (i.e. public) kamailio adds itself only for the private IP: *INVITE sip:12345678@mydmain.com <sip%3A12345678(a)mydmain.com> SIP/2.0Record-Route: <sip:172.31.25.124:5080;lr;did=9da.3a61;nat=yes>Via: SIP/2.0/UDP 172.31.25.124:5080;branch=z9hG4bKf05e.979fd257ac7f288804ef146d12c1e0fb.0Via: SIP/2.0/UDP 172.31.6.1:5080;received=172.31.6.1;rport=5080;branch=z9hG4bKQ3H8mgHaUjaBm* So when INFO messages come from the provider to kamailio2, kamailio 2 tries to send the INFO straight to "172.21.25.124". Should i manually add a record-route when calling OUT with record_route_advertised_address("1.2.3.4:5090"); Or is there a better way of getting this working?

UAC Module
by Javier Valencia 18 Nov '20

18 Nov '20

Hi there! Configuring the UAC module to use "remote registers" in a Kamailio 4.4.3. Everything it's working except for the flags database field to which I always put a value of 0. But when Kamailio starts to launch the REGISTRATION that field does not persist in the DB. In the kamailio.cfg file I have not made any changes, I only use the remote registers DB feature. Is it normal behavior? Do I have any parameters not set or incorrectly set? Regards, JV

how to add URI parameter
by Sergiu Pojoga 18 Nov '20

18 Nov '20

Hi there, Does Kamailio have a function to add URI parameters? I looked around but couldn't find one. I refuse to believe Kamailio doesn't have one. There's a *add_uri_param(param)*, but that's strictly for R-URI. I need it for something else, Contact. Thanks, --Sergiu

Multiple Registrations via WebSocket & Cisco phones
by Melek Oktay 17 Nov '20

17 Nov '20

Hi, I am using FreeSwitches behind the Kamailio proxy server and I am trying to allow multiple registration to my extensions. So, following configuration is sample of my Kamailio modparam("registrar", "xavp_cfg", "reg") ...... $xavp(reg=>max_contacts) = 10; save("location"); .... I saw my phones could register with the same account credentials via several phones such as Cisco, Zoiper, Yealing etc. When the call is forward to this extension, all of them are ringing. Very Nice. But, when I am trying to REGISTER WebRTC supports soft-phones to my system and with the same account credentials, my extensions are not ringing like in the previous scenario. WebRTC uses Websocket (WS) technology and clients register to Kamailio via usrloc module. When the call is forward to this extension, Kamailio try to replicate WebRTC'S INVITE packet to other phones (Cisco, Yealing, zoiper etc) and none of them understand incoming INVITE request because of WebRTC supported protocols (ICE ,a=candidate) , in a brief, phones could not recognize/understand incoming WebRTC request. This is a really tough issue for me, how can I send appropriate INVITEs for each of them.

The Algorithm “13” - latency optimized dispatching
by Julien Chavanton 14 Nov '20

14 Nov '20

About The Algorithm “13” - latency optimized dispatching, Is now reviewed once and tested, it will most likely be ready to merge soon. I want to share my thoughts on it one more time as it is not too late to get more feedback before we merge. I think it is the best algorithm in most use cases, here is why : It is providing round-robin and fail-over with automatic de-prioritization of slow/unresponsive gateways. You probably asked yourself the following questions in the past : "How do I set the thresholds to put a gateway out of service ?" *ds_probing_threshold*, *ds_inactive_threshold* and timers ... - If your thresholds are too strict, you may end up running out of gateway. - If your thresholds are too tolerant, you may end up adding excessive delays to call establishment and using degraded gateways. The automatic de-prioritization can help to address this concern more efficiently by providing more flexibility. - it can react faster than lets say 2 consecutive timeouts. - it will not disable gateways but simply de-prioritize / reorder them if needed. The only main drawback I can imagine is when you always need to evenly distribute calls using round-robin. It may be needed sometimes but in this case it means you are willing accept to send calls to a degraded gateway or trough degraded network paths. Even if you may select to preset a mixture of round-robin sets, thanks to *ds_select_routes* however it will stay static, needs to be configured precisely, and will not react to degradation automatically. I hope this will help use to protect QoS and lower latency of calls routed by Kamailio. Feel free to let me know what you think Julien

rport parameter in VIA header in uac remote registration
by Jetse Verschuren 12 Nov '20

12 Nov '20

Hi, I'm currently trying to connect Kamailio, running in docker, to my FritzBox. The FritzBox is the modem provided by my ISP, with a builtin voip server which I can use to dial out (basically a PSTN gateway). In my setup I have a custom router/firewall/NAT between the FritzBox and the server. When I connect LinPhone to the FritzBox, from behind the NAT, it works fine. But when I use the Kamailio uac remote registration, I don't get a response. After some investigation with wireshark, I found that the the SIP response from the FritzBox comes on the wrong port, and gets rejected by the NAT. The request comes from port 1025, but the response is sent to port 5060. I compared the requests from LinPhone and Kamailio, and combined with some research, found it probably was the rport option in the VIA header. >From what I read, it basically signals the uas to use the source port to reply to, instead of the port indicated in the request, which would be necessary to effectively go through a NAT. After reading a lot of documentation (and even parts of the source), I wasn't able to find an option to enable this option. Is there some option I completely missed, or is it not possible? Or am I completely wrong in my "diagnosis"? Thanks in advance, Jetse

Having trouble Setup Kamailio as a load balancer for Asterisk servers using module dispatcher
by Usama Shaikh 11 Nov '20

Hello Everyone. I am having trouble to setting up kamailio for load balancing for asterisk servers. I am using module dispatcher for load balancing AND two different servers for kamailio and asterisk. I am doing it first time and have not exact idea about its all configs… but i have researched and done so far, now need help from you guys. Currently, trying to setup with the one kamailio and one asterisk then will go ahead if I get any success… using MariaDB MySQL for the dispatcher data. Simply I want to do is : 1. Register my asterisk devices with kamailioIP (and I am able to do this using below configs) Devices are getting register with the asterisk from with kamailioIP 2. I want to receive calls on the registered devices with KamailioIP (and i am not able to do this) WORK FLOW: KAMAILIO IP = XX.XX.XX.95 on port 5060 and Asterisk IP = XX.XX.XX.164 on port 5060 SIP Device(ZOIPER) -------->>>>KAMAILIO SERVER(device register/load balancer)--------->>> ASTERISK SERVER Please have a look into my configuration files and let me know if anything is missing or wrong in these.

Expire timeout for notify message answer
by Victor Litvinov 10 Nov '20

10 Nov '20

Hello dear community. We use a presence module with the enabled option "timeout_rm_subs". And we face issues that subscriptions remove too early. We expect that it will be removed after the fr_timer, but it is removed after 1 second. We I can see in log (i'm add additional logs): when we send NOTIFY: tm [timer.c:491]: retr_buf_handler(): timer retr_buf_handler @1436309038 (timer_ln 0x7f4708f45bd0 -> rbuf 0x7f4708f45bb0 -> [0x7f4708f458a0 <-> 11592:145228 527]) tm [timer.c:492]: retr_buf_handler(): fr_expire 1436309054 T1 4000 T2 4000 fr_timeout 80 tm [timer.c:536]: retr_buf_handler(): new interval 4000 ms / 64 ticks (max 4000 ms) when timer expire: tm [timer.c:491]: retr_buf_handler(): timer retr_buf_handler @1436309054 (timer_ln 0x7f4708f45bd0 -> rbuf 0x7f4708f45bb0 -> [0x7f4708f458a0 <-> 11592:145228 527]) tm [timer.c:492]: retr_buf_handler(): fr_expire 1436309054 T1 4000 T2 4000 fr_timeout 80 tm [timer.c:367]: final_response_handler(): transaction [0x7f4708f458a0 <-> 11592:145228527] scheduled for deletion tm [timer.c:424]: final_response_handler(): stop retr. and send CANCEL (0x7f4708f458a0) and then subscription remove. As we can see the fr_expire variable was set to ticks+16 ( 1 second). And another strange thing that T1 and T2 timers are the same. So the question is if this behaviour is correct, how can we configure the presence module fr_timer as an expiration value for the answer to notify? And can we use it without retransmissions?

How to modify INVITE Request Line string
by Jose Figueroa 09 Nov '20

09 Nov '20

Hello everybody, Today I received a request from a carrier which needs us to send the calls using a prefix in the INVITE header. I am reading the documentation for kamailio 4.3.x but I havent found anything I can use in order to modify the Request Line (INVITE) string. I need to change from this: INVITE sip:123456789@IP:5060 to this: INVITE sip:PREFIX123456789@IP:5060 If you can guide me to the right direction would be more than great. Thanks -- Jose Figueroa Senior Software Engineer

Hi, How to do git clone of kamailio source code with minor version. I could only do git checkout of 5.3 version and it is automatically taking latest stable version. I don't need in this way. I need to do git clone of exact version of kamailio source code . Example - if I need 5.3.6 version.. exact version source code has to be git checked out from kamailio website. How to do that .. kindly let me know.. Thanks, Pavithra

Re: [SR-Users] Proxy configuration that exit dialog afer INVITE -> OK
by Yufei Tao 07 Nov '20

07 Nov '20

Hi, Here's an example kamailio.cfg that uses record_route so in-dialog requests will go through the Kamailio proxy: https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg There are many other example cfg files: https://github.com/kamailio/kamailio/tree/master/misc/examples Any server that wants to see the in-dialog messages needs to add itself to the record route list when receiving the initial INVITE for example.

Kamailio dump configuration and exit?
by Brandon Armstead 07 Nov '20

07 Nov '20

Is there a similar hook to make kamailio dump its current configuration it is reading including ... included files, i.e. similar to nginx -T root@main:/home/brandon# nginx -h nginx version: nginx/1.14.2 Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives] Options: -?,-h : this help -v : show version and exit -V : show version and configure options then exit -t : test configuration and exit -T : test configuration, dump it and exit -q : suppress non-error messages during configuration testing -s signal : send signal to a master process: stop, quit, reopen, reload -p prefix : set prefix path (default: /usr/share/nginx/) -c filename : set configuration file (default: /etc/nginx/nginx.conf) -g directives : set global directives out of configuration file Thanks for your time in advance!

send_reply() related feature request
by Juha Heinanen 06 Nov '20

06 Nov '20

Many times (especially when there is a hacking attempt) I want to close TCP or TLS session after sending reply. So, for example, I write: set_reply_close(); send_reply("403", "Forbidden"); It would be more convenient if these two calls could be combined into one, for example: send_reply_and_close("403", "Forbidden"); -- Juha

Re: [SR-Users] sr-users Digest, Vol 186, Issue 5
by Yufei Tao 05 Nov '20

05 Nov '20

Hi, Here's an example kamailio.cfg that uses record_route so in-dialog requests will go through the Kamailio proxy: https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg There are many other example cfg files: https://github.com/kamailio/kamailio/tree/master/misc/examples Any server that wants to see the in-dialog messages needs to add itself to the record route list when receiving the initial INVITE for example. If a server is not in the list of record routes, then in-dialog requests will not be sent to the server. Headers that are most important in terms of routing are R-URI, Route, Record-Route, Contact, Via. Via header is for routing responses, while Record-Route is for in-dialog requests.

tsilo - failure to add branches (-1)
by Jurijs Ivolga 05 Nov '20

05 Nov '20

Hi, I have several Kamailio proxies - loadbalancer which is used as TLS offload and Authorization server and behind registrar servers. In this case I can't make tsilo work on the registrar server. I'm always getting: "tm [t_append_branches.c:172]: t_append_branches(): failure to add branches (-1)" If I use just one Kamailio which is used as Authorization and Registrar server then tsilo works as expected. Looks like kamailio where I run ts_append tries to connect to UAC directly and not through Loadbalancer. Any ideas? How can I troubleshoot this? Thank you! Jurijs

Proxy configuration that exit dialog afer INVITE -> OK
by Adrian Tabacioiu 05 Nov '20

05 Nov '20

Hello all, Am I new in the usage of kamailio, sorry if I ask somehow something simple or terribly wrong . I need to test a configuration of Kamailio which exit the dialog between UA after the first OK (that means it will not receive the following ACK, BYE). I understand that in theory this is possible in two configuration types: - no Record Route header - or stateless proxy First question: Am I correct with the choices above? Can I find example configuration for this two modes ? Question 2: two or more proxy should be inter-connected, removing the Record Route header would interfere with proxy routing ? (should not the "Via" information be sufficient?) Thank you in advance for help. Best regards, Adrian Tabacioiu

Kamailio in VMware with Fault Tolerance on
by Patrick Wakano 03 Nov '20

03 Nov '20

Hello list, Hope you are all good! Recently, the issue https://github.com/kamailio/kamailio/issues/2535 has been investigated and the utilization of the feature vsphere Fault Tolerance is linked as a source of network latency and probably CPU allocation latency. This increases the chances of the mentioned issue to happen. So I would just like to ask if anyone out there is using Kamilio in a VMware environment with Fault Tolerance on? How is the experience? Kind regards, Patrick Wakano

http_async_client
by Brandon Armstead 03 Nov '20

03 Nov '20

kamailio 5.5.0-dev3 I'm unsure if this is expected behavior, so thought I would ask... When using http_async_query("URI", "ROUTENAME") request_route { route(AUTH); # this does not get executed below route(AUTH) xinfo("[$ci][$rm] we hit this line"); } route[AUTH] { t_newtran(); http_async_query("URI", "ROUTENAME"); } route[ROUTENAME] { # do stuff here to check authentication and return if(auth + registration) { append_hf("Path...."); msg_apply_changes(); # this fails and errors out about incorrect route # ^ invalid usage - not in request route or a reply save("location"); } if(auth + invite) { # route to pstn } } Expected behavior: to be able to obtain some processing / information gathering about authentication with the call and additional information possibly and return to normal routing. As-is now I've to move the actions all into ROUTENAME for kamailio to continue processing, it does not go back to request_route { }. # this does not get executed below route(AUTH) Is this expected behavior, or am I missing something? If I do catch route(AUTH) with a hash table and prevent its execution after first run, the avp's from the transaction created are not available in request_route that were set in ROUTENAME.

htable + event_routes + mod-init + htable:expired
by Brandon Armstead 02 Nov '20

02 Nov '20

Running 5.5.0-dev3 modparam("htable", "htable", "ipban=>size=8;autoexpire=300;dmqreplicate=1;") modparam("htable", "enable_dmq", 1) modparam("htable", "dmq_init_sync", 1) modparam("htable", "timer_procs", 4) modparam("htable", "timer_interval", 5) modparam("htable", "db_expires", 1) modparam("htable", "htable", "account=>size=4;dmqreplicate=1;") modparam("htable", "htable", "server=>size=4;autoexpire=15;") I'm attempting to retrieve an auth token in the init process and also refresh the token upon expiration in the htable:expired event. I'm seeing some behavior where every other execution of htable:expired the variable $sht(server=>auth::token) is set per kamcmd htable.dump server, however xinfo() reports that the token was retrieved in the variable $sht (server=>auth::token). Please see remaining event route config below: event_route[htable:mod-init] { # generate auth token into http_client_query("https://www.cryy.com/api/auth/token", '{"email": " brandon(a)cryy.com", "password":"XXXX"}', "$var(result)"); sht_lock("server=>auth::token"); $sht(server=>auth::token) = $var(result); sht_unlock("server=>auth::token"); xinfo("AUTH_TOKEN_RECEIVED, $sht(server=>auth::token)"); } event_route[htable:expired:server] { # process expired htable, renew auth token xinfo("AUTH_TOKEN_EXPIRED, lets retrieve a new one"); http_client_query("https://www.cryy.com/api/auth/token", '{"email": " brandon(a)cryy.com", "password":"XXXX"}', "$var(result)"); sht_lock("server=>auth::token"); $sht(server=>auth::time) = $TS; $sht(server=>auth::token) = $var(result); sht_unlock("server=>auth::token"); xinfo("AUTH_TOKEN_RECEIVED, $sht(server=>auth::token)"); xinfo("AUTH_TOKEN_TIME, $sht(server=>auth::time)"); } I've tried both with locking and unlocking. Also one last thing worth mentioning is that on the alternation where kamcmd htable.dump server shows no auth token, $sht(server=>auth::time) is available, when the auth token is visible in kamcmd htable.dump server there is no sht(server=>auth::time) returned. Also just to be explicitly clear -- xinfo() always returns AUTH_TOKEN_RECEIVED correctly in both event routes. Perhaps I'm over looking something -- thank you for the help in advance. - Brandon

outgoing TCP connection ID

Hi there, Is there a PV that exposes the outgoing TCP connection ID? $conid seems to be for received only. *$conid - The TCP connection ID of the connection the current message arrived on for TCP, TLS, WS, and WSS. Set to $null for SCTP and UDP.* The objective is to check the status of the egress TCP connection like for e.g.: if(!tcp_conid_state(conid)) { Thanks. --Sergiu

Missing refresher parameter in the Session-Expires header and Min-SE header
by Jose Figueroa 01 Nov '20

01 Nov '20

Hello everybody, I am trying an INVITE with a SBCs but fails, finding out it seems the Session-Expires doesn't include the param refresher= and according to this closed issue is already included https://github.com/kamailio/kamailio/issues/288 but I cannot achive this, I read the sst module documentation but I don't see anything related this parameter. So, in summary the SBC expects the following: Session-Expires: 1800; refresher=uac; Min-SE: 600 I set only: modparam("sst", "enable_stats", 1); modparam("dialog", "dlg_flag", 5) modparam("sst", "sst_flag", 6); modparam("sst", "min_se". 1800); Now on the invite I the setflag(); 5 and 6 so I see now the header Session-Expires: 1800 but not the refresher=uac; and also I don't see how to set the Min-SE:600 Could you please point me to the right direction? Any hint would be very helpful. -- Jose Figueroa Software Engineer

Confusion about TCP worker ports
by Noah Mehl 30 Oct '20

30 Oct '20

Hey all, I’m a little stuck on an implementation of a set of dispatchers via TCP. There are some oddities about the behavior of the TCP source port of the Kamailio tcp worker/s, and maybe this is expected, but it doesn’t seem valid. For instance, I have a dispatcher: "RECORDS": [{ "SET": { "ID": 1, "TARGETS": [{ "DEST": { "URI": “sip:2.2.2.2:5060;transport=tcp", "FLAGS": "AP", "PRIORITY": 5 } }] } }] But when Kamailio sends an OPTIONS keep alive, the source port for the worker is 33940, and not 5060 (which is the TCP listen port), as received by Freeswitch: recv 447 bytes from tcp/[1.1.1.1]:33940 at 18:58:24.958720: ------------------------------------------------------------------------ OPTIONS sip:2.2.2.2:5060;transport=tcp SIP/2.0 Via: SIP/2.0/TCP 1.1.1.1;branch=z9hG4bK1525.80a9e442000000000000000000000000.0 To: <sip:2.2.2.2:5060;transport=tcp> From: <sip:inbound-kamailio-01>;tag=3c52ba62ee4c4621b9660728159919d3-cda8066f CSeq: 10 OPTIONS Call-ID: 3aa18693487268dc-2790(a)1.1.1.1 Max-Forwards: 70 Content-Length: 0 User-Agent: kamailio (5.4.2 (x86_64/linux)) ------------------------------------------------------------------------ Also, I get weird debug messages when this tcp worker is spun up (specifically about Resource temporarily unavailable): 11(2790) DEBUG: dispatcher [dispatch.c:3340]: ds_ping_result_helper(): probe all, mode DS_PROBE_ALL 11(2790) DEBUG: dispatcher [dispatch.c:3383]: ds_ping_set(): probing set #1, URI sip:2.2.2.2:5060;transport=tcp 11(2790) DEBUG: dispatcher [dispatch.c:3414]: ds_ping_set(): Default ping_from: sip:inbound-kamailio-01 11(2790) DEBUG: dispatcher [dispatch.c:3424]: ds_ping_set(): Default outbound proxy: 11(2790) DEBUG: tm [uac.c:450]: t_uac_prepare(): next_hop=<sip:2.2.2.2:5060;transport=tcp> 11(2790) DEBUG: tm [uac.c:158]: dlg2hash(): hashid 21073 11(2790) DEBUG: <core> [core/tcp_main.c:1993]: tcp_send(): no open tcp connection found, opening new one 11(2790) DEBUG: <core> [core/ip_addr.c:229]: print_ip(): tcpconn_new: new tcp connection: 2.2.2.2 11(2790) DEBUG: <core> [core/tcp_main.c:1175]: tcpconn_new(): on port 5060, type 2, socket -1 11(2790) DEBUG: <core> [core/tcp_main.c:1494]: tcpconn_add(): hashes: 2712:0:0, 1 11(2790) DEBUG: <core> [core/tcp_main.c:2886]: tcpconn_1st_send(): pending write on new connection 0x7f24e64c1e18 sock 8 (-1/447 bytes written) (err: 11 - Resource temporarily unavailable) 11(2790) DEBUG: tm [uac.c:678]: send_prepared_request_impl(): uac: 0x7f24e65285a8 branch: 0 to 2.2.2.2:5060 11(2790) DEBUG: <core> [core/onsend.c:50]: run_onsend(): required parameters are not available - ignoring 27(2806) DEBUG: <core> [core/tcp_main.c:3792]: handle_ser_child(): read response= 7f24e64c1e18, 5, fd 46 from 11 (2790) 27(2806) DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0x56490f0f8060, 46, 2, 0x7f24e64c1e18), fd_no=37 27(2806) DEBUG: <core> [core/io_wait.h:782]: io_watch_chg(): DBG: io_watch_chg (0x56490f0f8060, 46, 0x1, 0xffffffff) fd_no=38 called 27(2806) DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0x56490f0f8060, 46, -1, 0x0) fd_no=38 called 27(2806) DEBUG: <core> [core/tcp_main.c:4457]: handle_tcpconn_ev(): sending to child, events 1 27(2806) DEBUG: <core> [core/tcp_main.c:4127]: send2child(): selected tcp worker idx:0 proc:19 pid:2798 for activity on [tcp:1.1.1.1:5060], 0x7f24e64c1e18 19(2798) DEBUG: <core> [core/tcp_read.c:1749]: handle_io(): received n=8 con=0x7f24e64c1e18, fd=8 19(2798) DEBUG: <core> [core/tcp_read.c:1548]: tcp_read_req(): content-length=0 19(2798) DEBUG: <core> [core/parser/msg_parser.c:620]: parse_msg(): SIP Reply (status): 19(2798) DEBUG: <core> [core/parser/msg_parser.c:622]: parse_msg(): version: <SIP/2.0> 19(2798) DEBUG: <core> [core/parser/msg_parser.c:624]: parse_msg(): status: <200> 19(2798) DEBUG: <core> [core/parser/msg_parser.c:626]: parse_msg(): reason: <OK> 19(2798) DEBUG: <core> [core/parser/parse_via.c:1303]: parse_via_param(): Found param type 232, <branch> = <z9hG4bK1525.80a9e442000000000000000000000000.0>;

Double port in TO header
by David Villasmil 30 Oct '20

30 Oct '20

Hello guys, This happened to me a long time ago but i totally forgot the reason. I using a simple dispatcher, and when relaying out to the destination, kamailio is adding an additional :5060 port to the To header: To: <sip:910609738@172.31.6.1:5080:5060> The Destination is actually 172.16.6.1:5080, i don't know why Kamailio is adding that :5060 The dispatcher is if (!ds_select_dst($var(dispatcher_outbound), "4")) { xlog("[DISPATCH]: ds_select_dst FAILED!\n"); send_reply("404", "No destination"); exit; } else { xlog("[DISPATCH]: ds_select_dst was succesful\n"); } xlog("L_DBG", "[DISPATCH]: going to <$ru> via <$du>\n"); t_on_failure("RTF_DISPATCH"); route(RELAY); Any ideas? I totally forgot... and it's late, i guess... Thanks! David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Building db_postgres with PostgreSQL headers and libs in non-standard location
by Chaigneau, Nicolas 29 Oct '20

29 Oct '20

Hello, I'd like to build Kamailio module db_postgres, with the PostgreSQL headers and libs in a non-standard location. I'm trying to figure out how to do that, if it's possible, without having to edit db_postgres/Makefile. I see in the Makefile that it's trying to find the files relative to $(LOCALBASE): # use standard know paths # libpq-fe.h locations DEFS +=-I$(LOCALBASE)/include -I$(LOCALBASE)/pgsql/include \ -I$(SYSBASE)/include/pgsql -I$(SYSBASE)/include/postgresql \ -I$(SYSBASE)/include/postgresql/8.0 LIBS +=-L$(LOCALBASE)/lib -L$(LOCALBASE)/pgsql/lib \ -L$(LOCALBASE)/lib/pgsql -lpq However, LOCALBASE (which defaults to /usr/local) is used for many things other than PostgreSQL, so changing that is not a great idea, I think... Any idea ? Regards, Nicolas. This message contains information that may be privileged or confidential and is the property of the Capgemini Group.

Kamailio unresponsive with Dialog+DMQ
by Patrick Wakano 28 Oct '20

28 Oct '20

Hello list, Hope all are doing well! We are running load tests in our Kamailio server, that is just making inbound and outbound calls and eventually (there is no identified pattern) Kamailio freezes and of course all calls start to fail. It does not crash, it just stops responding and it has to be killed -9. When this happens, SIP messages are not processed, dmq keepalive fails (so the other node reports as down), dialog KA are not sent, but Registrations from UAC seem to still go out (logs from local_route are seen). We don't have a high amount of cps, it is max 3 or 4 per sec, and it gets around 1900 active calls. We are now using Kamailio 5.2.8 installed from the repo on a CentOS7 server. Dialog has KA active and DMQ (with 2 workers) is being used on an active-active instance. >From investigation using GDB as pasted below, I can see UDP workers are stuck on a lock either on a callback

Kamailio v5.4.2 Released
by Daniel-Constantin Mierla 27 Oct '20

27 Oct '20

Hello, Kamailio SIP Server v5.4.2 stable release is out. This is a maintenance release of the latest stable branch, 5.4, that includes fixes since the release of v5.4.1.

Re: [SR-Users] Load balance on HA scenario
by Yufei Tao 22 Oct '20

22 Oct '20

Hi Duarte, I'm not sure if your situation is more complicated than mine. I have two dispatcher nodes in the HA setup, with real IPs say IPa, IPb. They share a floating/virtual IP, let's call it VIP. Both nodes listen to the VIP (not its real IP), and use the VIP as the dispatcher's socket. In this case the master node which has the VIP can always send OPTIONS pings fine. My problem was with the backup node, which doesn't have the VIP so fails to send OPTIONS pings. Joel Serrano gave a good suggestion: both nodes start up with polling disabled, and only when a node turns master it enables the polling. This has solved my problem. Cheers, Yufei

Incoming DID calls routing to subscriber
by Jose N Figueroa 22 Oct '20

22 Oct '20

Hello everybody, I'm trying to route incoming calls to kamailio with specific subscriber but I can't make it working. The complete scenario is: SoftSwith -> kamailio 5.3 -> zoiper What i'm trying to do is to receive a call into the zoiper when I dial specific DID which is already coming into the kamailio. It goes until the routing from kamilio to the subscriber account but it keeps in INVITE command, no response from the subscriber. Any help would be great! This is what I've been trying but no luck yet: if($rdir(name)=="downstream") { xlog("DID request was incoming call, called number: $rU caller_id: $fU and source_ip $si \n"); $sht(rtpProxy=>mip_$ci)=1; # We should take the called_number as username in table # Also validate if the number has active that DID, balance if needed, etc. # route(validate_customer); # I know, hardcoded for testing sql_xquery("ca", "select * from location where username = 1212 ", "ra"); $avp(location_addr) = $xavp(ra=>received); xlog("DID did_incoming location is $xavp(ra=>received) \n"); # Validate SIP OK #setflag(SIP_IP_OK); #$rU=$avp(dnis); #$rd=$avp(identity); #$rp=$avp(port); # uac_replace_to($xavp(ra=>contact)); uac_replace_to("sip:1212@voip.x.net:5060"); # $ru = $var(duri); $ru=$xavp(ra=>contact); $ru="sip:1212@voip.x.net:5060"; route(RELAY); # t_on_failure("dst_failure"); # t_on_reply("dst_reply"); if(!t_relay()) { sl_reply_error(); exit; } exit; } -- Regards, Jose N Figueroa

Load balance on HA scenario
by Duarte Rocha 21 Oct '20

21 Oct '20

Greetings, I have two machines with Kamailio in a HA setup with replicated DB. For simplicity let's say each machine has one HA IP and that IP can jump to the other machine in case something happens (kamailio stopping, etc). I'm using Dispatcher with load balance configuration. I have Dispatcher configured so that each peer has one instance for socket with HA IP 1 and HA IP 2. In order for this to work correctly on the load balance scenario I must disable via RPC command the peer which has the socket that doesn't belong to the machine. I also must do it every time the IP jumps back and forth, which adds complexety to my system. Does Dispatcher has any sort of help on this? It could not include peers with sockets IPs that don't belong to the machine in the destination set, for example. Is this possible? I could also work with failover support but i would rather avoid having so many failovers. Best Regards,A

How to read "duid" from dispatcher.list in kamamilio.cfg

How can I read this value in the configuration file? Jani Biju Babjan

Re: [SR-Users] Load balance on HA scenario
by Yufei Tao 20 Oct '20

20 Oct '20

Hi Duarte, Not sure if I understand it correctly but are you trying to set up an HA pair of dispatchers? If so I am doing it differently in that, I use the Virtual/floating IP (VIP) as socket. This way the master node (which has got the VIP) can send OPTIONs pings out fine but the backup node won't be able to send. Functionally it is fine, but the backup node keeps logging errors because it doesn't have the VIP: ERROR: <core> [core/udp_server.c:599]: udp_send(): sendto(sock, buf: 0x7f0e6b54e2e0, len: 372, 0, dst: (192.168.213.143:5060), tolen: 16) - err: Network is unreachable (101) ERROR: tm [../../core/forward.h:231]: msg_send_buffer(): udp_send failed When FO happens, the backup node becomes master and takes the VIP, and it functions correctly. But I haven't worked out how to avoid the ERROR loggings on the backup node. Maybe someone else has any better ideas/suggestions? Cheers, Yufei

No retry on INVITE
by Allan Kristensen 20 Oct '20

20 Oct '20

Hello, I'm trying to get Kamailio to retry INVITE. We have a Freeswitch which is sending INVITE to a sip user via Kamailio proxy using static ip/location. All is well, calls are flowing, but sometimes INVITE from kamailio to user is lost and no attempt to retry is occurring and so after 30 sec kamailio just returns 408 Request timeout. Call flow is like this: FS Kamailio User --- INVITE --> <-- 100 Trying --- INVITE ---> (Waiting 30 secs) <-- 408 Timeout --- ACK ---> So assume we have failed in handling retries somehow. Kamailio is running stateless, but other retries are working, so I assume this is not a problem? Can someone perhaps point us in the right direction on where to solve this? Kamailio is version 5.2.4 Thank you... /Allan

Re: [SR-Users] SRTP
by Yufei Tao 20 Oct '20

20 Oct '20

Hi, Like Olle said RTPEngine is perfectly capable of handling one leg in RTP the other in SRTP. When looking up RTPEngine's documentation, may be worth checking these out: SRTP SDES-unencrypted_srtp SDES-unencrypted_srtcp SDES-unauthenticated_srtp e.g. try apply these flags to rtpengin_offer() on the incoming RTP leg, to get RTPEngine to add encryption to the outgoing leg etc. Cheers, Yufei

Re: [SR-Users] Kamailio 5.2.5 - Need help with rtpengine error
by Yufei Tao 20 Oct '20

20 Oct '20

Hi Andrew, Like Alex said, have a look at the commands RTPEngine received and the responses it sent in the history of the call, and see if RTPEngine has ever received any commands regarding this call, or, if the call has been deleted from RTPEngine. You can raise the RTPEngine logging level to 6 for example so you can see the command/responses of RTPEngine. Cheers, Yufei

TOPOS module and fix_nated_contact
by Minh Phan 19 Oct '20

19 Oct '20

Hi List, I am using Topos module to hide network topology. I am having a problem of routing the ACK request for REINVITE. Here is the schema: A KAMAILIO B 1. --------- INVITE --------> 2. <---- 180 RINGING --- 3. <---- 200 OK --- 4. ---- ACK ---> 5. <--------- (RE) INVITE -- 6. --------- OK ---> 7. <---- ACK ----- (THIS ACK IS SENT TO PRIVATE IP OF A) I use TOPOS module along with fix_nated_contact as I would do normally for natted UAs. The first ACK (4) is routed correctly but not the second one (7), which is routed to the PRIVATE IP of A instead of routing to its public address. Has anyone run into this problem while using TOPOS module? How could I make them work together? Best Regards, Minh Phan

Libphonenumber - Updating metadata
by Zach Nielsen 18 Oct '20

18 Oct '20

Hey all, I've been using the PHONENUM module, which uses Google's libphonenumber library, to perform number validation among other handy things within the route script. One problem I've run into however is the metadata in the latest stable (5.4) repo is pretty stale. I'm curious if anyone is running this module, and if so how they've gone about updating the metadata used by the underlying library. If I have to ditch the repo and compile everything manually, that's not a huge deal. Just hoping there's another way. Thanks! Zach

No trusted table found
by Jon Bonilla (Manwe) 17 Oct '20

17 Oct '20

Hi all Just installed a kamailio 5.4.1 for a simple proxy scenario. I created the version,address and trusted tables, and added some ips to the trusted via kamctl. If I execute "kamctl trusted show" I see the list of servers. But with "kamctl trusted dump" I receive { "jsonrpc": "2.0", "error": { "code": 500, "message": "No trusted table" }, "id": 13063 } when I start kamailio with debug I see these messages: b_do_submit_query(): submitted query: select `table_version` from `version` where `table_name`='trusted', result 0 my version table looks like this: +----+------------+---------------+ | id | table_name | table_version | +----+------------+---------------+ | 1 | version | 1 | | 2 | trusted | 6 | | 3 | address | 6 | +----+------------+---------------+ any hints? cheers, Jon -- PekePBX, the multitenant PBX solution https://pekepbx.com

TLS connection from Chrome to Kamailio fails
by Juha Heinanen 17 Oct '20

17 Oct '20

White testing WebRTC, I noticed that TLS connection from Chrome browser 85.0.4183.121 to Kamailio's (master version) TLS listening port fails. Chrome sends Client Hello and K responds with Server Hello. After that Chrome terminates the handshake by sending TCP FIN. Connection setup from Firefox works fine. After receiving Server Hello, is sends Change Cipher Spec, etc. My K is using Let's Encrypt server certificate and is server tls_method is TLSv1.2+. Any ideas what goes wrong? Has anyone else experienced this? -- Juha

usrloc_dmq - Suddenly stopped usrloc replication
by José Seabra 16 Oct '20

16 Oct '20

Hello there, Suddenly the usrloc replication through DMQ stopped, but the interesting thing is that DMQ cluster status is OK, htable replication still working only usrloc_dmq stopped working. I increased the kamailio loglevel to 3 in order to see if there was some log related and then registered a peer, but the only DMQ logs that I see are related with notification_peer and htable replication, nothing related with usrloc_dmq. What I can do more here to try to understand what went wrong? I haven't restarted the cluster yet, because I would like to try to understand the root cause of this issue. Any advice would be appreciated Thank you -- Cumprimentos José Seabra
