Hi, looks like in your script, in the SENDPUSH route, you set the luaret var to 0 then you check if it's value is != 1, in which case you reply 501, Unknown Destination. Since you never change the var value you are always hitting this case.

How to forward REGISTERs to Asterisk in kamailio with dispatcher module with several Asterisk PBXs?
by Tickling Contest 24 Jul '16

24 Jul '16

Hello, When using Kamailio with the dispatcher module for Asterisk load balancing, I am offloading REGISTERs to Kamailio (works fine), but would like to forward the REGISTERs to Asterisk so that outgoing calls from Asterisk will be possible. I know this is not strictly necessary (e.g., just use Kamailio to forward everything), but I have a lot of application logic behind my Asterisk boxes (using ARI) and so I don't want that to break. Thereby, I do need this information in Asterisk as soon as possible from Kamailio. Let's say I have three boxes Asterisk_1, Asterisk_2 and Asterisk_3 in the dispatcher module like so: 1 sip:192.168.1.201:5060;transport=tcp 1 sip:192.168.1.202:5060;transport=tcp 1 sip:192.168.1.203:5060;transport=tcp My system has endpoints as numerical extensions, from 101 to 110. When a new endpoint registers with kamailio (and authenticates), I would like to send the REGISTER to Asterisk. But I have the following questions: (a) Which Asterisk? I could send it to a round-robinned Asterisk (say, Asterisk_2), but that Asterisk may not be the one responsible for handling calls outbound for the endpoint that just registered. Even if I use "hash over auth username" instead of round-robin (In http://www.kamailio.org/docs/modules/4.0.x/modules/dispatcher.html#idp16940…, choose 5 for "alg", for example) that wont solve this problem as an outbound request may come from another Asterisk box which won't have the requisite registration information. Should I forward REGISTERs to all Asterisk boxes? Maybe I won't have to deal with this issue as I use realtime and so the REGISTER information, sent to one Asterisk box, is available to all Asterisk boxes after the write to the realtime DB. Is my understanding correct? (b) How do I do this in kamailio.cfg? With some examples on the Internet for WITH_ASTERISK directive, I see that you do route[REGFWD] { if(!is_method("REGISTER")) { return; } $var(rip) = $sel(cfg_get.asterisk.bindip); $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + $sel(cfg_get.asterisk.bindport) + ";transport=tcp"; $uac_req(furi)="sip:" + $au + "@" + $var(rip); $uac_req(turi)="sip:" + $au + "@" + $var(rip); $uac_req(hdrs)="Contact: <sip:" + $au + "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport) + ">\r\n"; if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; uac_req_send(); } What is the equivalent for when you are using the dispatcher module and the kamailio.bindip and asterisk.bindip etc. are not set in the configuration, but instead should be procured from elsewhere? Any help is appreciated.

SIP Outbound / t_next_contacts()
by Colin Morelli 24 Jul '16

24 Jul '16

Hey all, I've got two layers of Kamailio proxies running. One set of edge proxies that are parking outbound connections and doing load balancing to a set of registrar/proxies. This is working well with one exception: I can't seem to get t_load_contacts/t_next_contacts working correctly for handling multiple outbound connections. It *appears* to work (though I haven't extensively tested) whenever there's more than one registration binding for an AOR. However, when there's only one, I get: 8(27) DEBUG: tm [t_serial.c:191]: t_load_contacts(): nr_branches is 0 8(27) DEBUG: tm [t_serial.c:194]: t_load_contacts(): nothing to do - only one contact! 8(27) DEBUG: tm [t_serial.c:455]: t_next_contacts(): no contacts in contacts_avp - we are done! 8(27) ERROR: <script>: t_next_contacts() failed I tried omitting the call to t_next_contacts(), thinking it should possibly only be used in failure_route. But when I do that (while leaving t_load_contacts), I get: 5(24) ERROR: tm [t_fwd.c:1730]: t_forward_nonack(): ERROR: t_forward_nonack: no branches for forwarding 5(24) WARNING: <core> [receive.c:258]: receive_msg(): error while trying script The relevant part of the config is: if (!lookup("location")) { $var(rc) = $rc; switch ($var(rc)) { case -1: xlog("L_INFO", "$ci|log|lookup of contacts for $ru returned no results\r\n"); send_reply("404", "Not Found"); exit; case -3: xlog("L_INFO", "$ci|log|lookup of contacts for $ru failed with code $var(rc)\r\n"); send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } if (!t_load_contacts() || !t_next_contacts()) { xlog("L_ERR", "t_load_contacts() failed\n"); sl_reply_error(); t_release(); exit; } Am I missing something else here? Note: it works fine if I remove t_load_contacts/t_next_contacts, but then I don't get proper handling of multiple sip.instance bindings/differing q values. Best, Colin

I apologize since this is a technical mail list and this question may not belong here but i need to fill a business requirement and need more information of big companies using kamailio, i am searching over the internet but if anyone can provide me with names of real carriers using kamailio will be very useful. Thanks again for any help in this case.

Dispatcher list not loading from dispatcher.list, but loading from DB
by Tickling Contest 23 Jul '16

23 Jul '16

Hello, I have a Kamailio 4.0.4 configured with the cfg file shown in https://gist.github.com/ticklingcontest/f96aa4d08b08dc4643056d73da24f0a5 The modparam for dispatcher sets the dispatcher file to be in /var/run/kamailio/dispatcher.list. However, I recently discovered that $ kamctl dispatcher show picks up the information from the kamailio DB instead of the dispatcher.list. What's going on? Any insight is appreciated. Thanks!

kamailio starts looping invites(some) back to itself.
by Aqs Younas 22 Jul '16

22 Jul '16

Hi, I am using http_async_client and dispatcher modules of Kamailio. Here is scenario! http_async_client makes calls to an API to get groupid upon which dispatcher sends calls. I am using SIPp to generate calls with 100 cps. I see some calls being failed with an error cause, 483 Too Many Hops. Taking the trace shows Kamailio routing some calls to itself. I think this is not a configuration issue since all calls are same(follow same logic) and some calls get failed. Any pointer is much appreciated. Best Regards.

sip options not relaying
by gerry kernan 22 Jul '16

22 Jul '16

Hi I have a kamailio proxy in front of asterisk ver 13 servers. I'm using path support to route to the relevant asterisk server depending on the domain in the sip header. The incoming registers & invites from sip endpoints get routed to the correct asterisk server , but when asterisk is sending sip options to the end points my kamailio config is not routing the option on to the endpoint . Kamailio debug shows error below ERROR: <script>: 192.168.200.131 OPTIONS sip:1333@192.168.200.112:5062 -- domain "192.168.200.112" is not found in domain table 192.168.200.131 Am I correct in thinking that this SIP option should be getting routed via my on-reply route. the sip option looks like it is failing here at the start of my config if (src_ip != BACKEND_NET4) { xlog("L_NOTICE", "FROM CLIENT IP: $si $rm $ru $td \n"); # SIP request packet client->backend if( !loose_route() ) { if (!lookup_domain("$td", "dattr_")) { xlog("L_NOTOCE" , "Domain lookup, $rm "); xlog("L_ERR", "$si $rm $ru -- domain \"$td\" is not " + "found in domain table $si\n"); drop(); } Sample of SIP option captured on the kamailio server OPTIONS sip:1333@192.168.200.112:5062 SIP/2.0 Via: SIP/2.0/UDP 192.168.200.131:5060;branch=z9hG4bK4f910445 Max-Forwards: 70 Route: <sip:192.168.200.148;lr;received=sip:87.198.223.83:16070> From: "Unknown" <sip:Unknown@192.168.200.131>;tag=as54cfb9df To: <sip:1333@192.168.200.112:5062> Contact: <sip:Unknown@192.168.200.131:5060> Call-ID: 257dea110f5255275aa38d9c45e0e235@192.168.200.131:5060 CSeq: 102 OPTIONS User-Agent: FPBX-2.11.0(13.10.0) Date: Fri, 22 Jul 2016 15:31:13 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer, path Content-Length: 0 OPTIONS sip:1333@192.168.200.112:5062 SIP/2.0 Via: SIP/2.0/UDP 192.168.200.131:5060;branch=z9hG4bK20611e3b Max-Forwards: 70 Route: <sip:192.168.200.148;lr;received=sip:87.198.223.83:16070> From: "Unknown" <sip:Unknown@192.168.200.131>;tag=as1b6a0faf To: <sip:1333@192.168.200.112:5062> Contact: <sip:Unknown@192.168.200.131:5060> Call-ID: 7f8ed5ea7a147f2b61269df862af7fae@192.168.200.131:5060 CSeq: 102 OPTIONS User-Agent: FPBX-2.11.0(13.10.0) Date: Fri, 22 Jul 2016 15:31:27 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer, path Content-Length: 0 Gerry Kernan Infinity IT | 17 The Mall | Beacon Court | Sandyford | Dublin D18 E3C8 | Ireland Tel: +353 - (0)1 - 293 0090 | E-Mail: <mailto:gerry.kernan@infinityit.ie> gerry.kernan(a)infinityit.ie Managed IT Services Infinity IT - <http://www.infinityit.ie/> www.infinityit.ie IP Telephony Asterisk Consulting - <http://www.asteriskconsulting.com> www.asteriskconsulting.com Contact Centre Total Interact - <http://www.totalinteract.com> www.totalinteract.com

Kamailio + Asterisk MWI Issues
by TEG AMJG 21 Jul '16

21 Jul '16

Dear list I am quite new to Kamailio and i know that probably this thread has been answered quite few times. But i have few questions I was able to configure Kamailio + Asterisk MWI with Kamailio handling the registration of users. The problem is that i am quite sure that is not the right way. What i did was just putting "subscribemwi=no" on every user declared on Asterisk and he will send NOTIFY's when a voicemail has been received for a particular user to Kamailio and Kamailio will just forward them to the endpoints (because he knows the location of the users). I know about the modules presence presence_xml and presence_mwi of Kamailio which will handle the subscription of users and send NOTIFY's but it is useless since I am not verifying any NOTIFY that comes from Asterisk, just forwarding. Now, some others solution are just a bunch of scripts that, for me, it doesnt make much sense since is the same idea like how i did it just more hacky and unnecesary, i guess?. This solution can be found here: http://saevolgo.blogspot.com/2012/07/asterisk-behind-kamailio-voicemail-mwi… There is another solution that i found in few threads here which i dont understand really well, is to send PUBLISH messages from Asterisk to Kamailio so Kamailio sends NOTIFY's with the event and content about the amount of voice messages in a particular mailbox. Some say that you need to create the message PUBLISH and send it with sipsak or another solution in Asterisk. For what i see in SIP documentation, the last solution seems a bit less of a hack lets say, more resilient. With all said, i have a few questions Is it the solution I made really a bad idea?. I havent take a lot of time understanding SUBSCRIBE/NOTIFY messages, just the basics, i dont know if there are some security issues i should think about in this particular flow. Should i check the status of the authorization of the subscription in Kamailio before forwarding the mesage (if there is a way, how)? or it really doesnt make sense at all? because after all, my endpoints receives the NOTIFY and "you have a new voicemail" message appears. Now, about the last solution, is there any guide of someone that has done that in a clean way?, may someone guide me how to construct the PUBLISH message and when should i send it?, should i create a cron or something?, this PUBLISH message needs to be send for every user?. may someone guide me (if this is considered a cleaner way of doing it) how to make this? Many of the answers in other threads about this are not enough to understand the idea as a whole, at least for me. Thank you very much in advance Alejandro -- - Saludos a todos

Kamailio stops accepting calls for few seconds after 80 CPS.
by Aqs Younas 21 Jul '16

21 Jul '16

Greeting list. I am doing the load test of Kamailio with SIPp using most basic script(kamailio.cfg) with logging level set to minimum to dispatch requests to SIPp UAS. This is my dispatcher code snippet. $avp(quality) = "1"; ds_select_dst("$avp(quality)", "4"); route(RELAY); At 70 CPS calls work fine. But if I increase CPS to 80, Kamailio stops accepting calls for few seconds and comes to life after being idle for some time. 100 CPS for sip proxy is not hot cake. Also, I see in http://www.kamailio.org/docs/openser-performance-tests/ tests were made with -l27 and -m7000 which looks wronged to me. ./sipp -sf uac_inv.xml <http://www.kamailio.org/docs/openser-performance-tests/data/uac_inv.xml> -rsa 192.168.2.102:5060 192.168.2.102:5070 -m 200000 -r 7000 -d 1 -l 27 There must be something wrong in my configuration since this cps is very low. kamailio -version version: kamailio 4.4.1 (x86_64/linux) 90be8b flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, 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_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 90be8b SHM_MEMORY=768 PKG_MEMORY=64 Any suggestion is much appreciated.
