by Karsten Horsmann 21 Jun '19

21 Jun '19

Good morning List! I have an issue with my kamcmd from kamailio 5.2.3 on CentOS 7.6 with kamailio-rpms. The kamcmd util can not find my registrations via command kamcmd uac.reg_enable auth_username FFFFFFFFFFFF kamcmd uac.reg_info l_username +49XXXXXXXX and soone. Only global commands for uac works. Whats going wrong with my kamcmd? Any ideas? Thank for your hints! # kamcmd uac.reg_dump { l_uuid: 49XXXXXXX l_username: +49XXXXXXXX l_domain: sip-trunk.telekom.de r_username: +49XXXXXXXX r_domain: sip-trunk.telekom.de realm: sip-trunk.telekom.de auth_username: FFFFFFFFFFFF auth_password: *************** auth_proxy: sip:reg.sip-trunk.telekom.de expires: 360 flags: 20 diff_expires: 129 timer_expires: 1561103682 reg_init: 1561101919 reg_delay: 3 } # kamcmd uac.reg_enable auth_username FFFFFFFFFFFF error: 404 - Record not found -- Kind regards Mit freundlichen Grüßen *Karsten Horsmann*

XMPP
by David Villasmil 19 Jun '19

19 Jun '19

Hello guys, I'm kind of confused as to what module exactly i need to user, let me explain: I have a service for DIDs and SMS from s.ms, i created a python script that connects to the service using xmpp to their jabber server with a user and a password, i.e.: xmpp_client.py MY-NUMBER(a)s.ms MY-PASSWORD What i do with that script is basically connect and wait to receive SMS, which i then insert in the proxy db (silo) and they get delivered by msilo. I have several numbers and doing this for every number seems stupid, so i started looking for a better solution, since the end user will be receive the message via SIP MESSAGE on they sip client. i came across kamailio/opensips' jabber and xmpp modules, but i'm not sure which (if any) to use, and even HOW to, or the actual architecture, since the documentation keeps talking about a local xmpp server? I would REALLY appreciate some help here. Thanks!

Question on Database Version Table
by JR Richardson 18 Jun '19

18 Jun '19

Hey All, I'm doing some upgrades and noticed database table version numbers have increased. database table adjustments: | address | production ver 3 | upgrade 5.2 ver 6 | need to add accountcode and notes column | dispatcher | production ver 3 | upgrade 5.2 ver 4 | need to add attr column | trusted | production ver 5 | upgrade 5.2 ver 6 | need to add ruri_pattern and priority column I run mysql master/slave so I'm concerned about the master database not having the correct version numbers or can I just update the version number in the table when I do the upgrade of the kamailio versions? Thanks. JR -- JR Richardson Engineering for the Masses Chasing the Azeotrope

Kamailio Crashing when using Evapi with CGRateS
by Efelin Novak 18 Jun '19

18 Jun '19

Hi folks, I am doing some experiments with Kamailio and Cgrates. To be precise I am testing evapi module. When in testing environment I do not have any problem. After redirecting some production traffic to this kamailio, It crashes in at random times (few minutes to 20). I didn't find any pattern here. CGRateS doesn't write anything in logs. I'm on the last 4.4 Kamailio (compiled recently). CGRateS is on the last version. Can you please point to how to continue with debugging? Thanks Efelin Here is the problem in syslog: kamailio[9594]: : <core> [mem/f_malloc.c:599]: fm_free(): BUG: fm_free: bad pointer 0x97894818 (out of memory block!), called from tm: h_table.c: free_cell_helper(185) - abortingkamailio[9608]: CRITICAL: <core> [pass_fd.c:277]: receive_fd(): EOF on 16 kamailio[9588]: ALERT: <core> [main.c:743]: handle_sigs(): child process 9594 exited by a signal 6 kamailio[9588]: ALERT: <core> [main.c:746]: handle_sigs(): core was not generated kamailio[9588]: INFO: <core> [main.c:768]: handle_sigs(): terminating due to SIGCHLD kamailio[9604]: INFO: <core> [main.c:823]: sig_usr(): signal 15 received kamailio[9606]: INFO: <core> [main.c:823]: sig_usr(): signal 15 received kamailio[9603]: INFO: <core> [main.c:823]: sig_usr(): signal 15 received bt full #0 0xb77d1424 in __kernel_vsyscall () No symbol table info available. #1 0xb7673661 in raise () from /lib/i386-linux-gnu/i686/cmov/libc.so.6 No symbol table info available. #2 0xb7676a92 in abort () from /lib/i386-linux-gnu/i686/cmov/libc.so.6 No symbol table info available. #3 0x082611a3 in fm_free (qmp=0x56779000, p=0x2d4e4f49, file=0x970932ee "tm: h_table.c", func=0x970935b7 "free_cell_helper", line=185, mname=0x97092d20 "tm") at mem/f_malloc.c:601 qm = 0x56779000 f = 0x56df046c __FUNCTION__ = "fm_free" #4 0x96fd0559 in free_cell_helper (dead_cell=0x56d935c4, silent=0, fname=0x970b90ca "timer.c", fline=648) at h_table.c:185 b = 0x56df0490 "CANCEL sip:00444123456@192.168.1.3:5060 SIP/2.0\r\nVia: SIP/2.0/UDP 192.168.1.2;branch=z9hG4bKb6ae.5d03d7e94e5ec25f34930629f434a006.1\r\nMax-Forwards: 66\r\nFrom: \"0044454321\" <sip:0044454321@i"... i = 1 rpl = 0x9797e818 tt = 0xbfe44c68 foo = 0x970ccb14 cbs = 0x0 cbs_tmp = 0x56d12b68 __FUNCTION__ = "free_cell_helper" #5 0x9706884f in wait_handler (ti=31715179, wait_tl=0x56d9360c, data=0x56d935c4) at timer.c:648 p_cell = 0x56d935c4 ret = 0 #6 0x08241e20 in timer_list_expire (t=31715179, h=0x567a3b68, slow_l=0x567a5394, slow_mark=1772) at timer.c:873 tl = 0x56d9360c ret = 0 #7 0x08242211 in timer_handler () at timer.c:938 saved_ticks = 31715179 run_slow_timer = 0 i = 748 __FUNCTION__ = "timer_handler" #8 0x0824266b in timer_main () at timer.c:977 No locals. #9 0x080f0005 in main_loop () at main.c:1699 i = 3 pid = 0 si = 0x0 si_desc = "udp receiver child=2 sock=192.168.1.2:5060\000\270\301\310V\270\301\310V\000\000\000\000\000\000\000\020c\000\000\000\001\000\000\000\000\000\000\000\374Q\344\277HO\344\277\341`&\b\230\071\220\227\004\000\000\000٧5\b$\271\065\bn\000\000\000\324\247\065\b\n\000\000\000\363\320\372\060", '\000' <repeats 11 times> nrprocs = 3 woneinit = 1 __FUNCTION__ = "main_loop" #10 0x080f6b3a in main (argc=13, argv=0xbfe45374) at main.c:2644 cfg_stream = 0x8491008 c = -1 r = 0 tmp = 0xbfe4577c "" tmp_len = 1 port = 0 proto = 0 options = 0x8350e74 ":f:cm:M:dVIhEeb:l:L:n:vKrRDTN:W:w:t:u:g:P:G:SQ:O:a:A:x:X:" ret = -1 seed = 1759582648 rfd = 4 debug_save = 0 debug_flag = 0 dont_fork_cnt = 0 n_lst = 0xbfe452a0 p = 0x805cc8c "[\201Ä4;" st = {st_dev = 14, __pad1 = 0, st_ino = 6161, st_mode = 16877, st_nlink = 2, st_uid = 109, st_gid = 111, st_rdev = 0, __pad2 = 0, st_size = 60, st_blksize = 4096, st_blocks = 0, st_atim = {tv_sec = 1560160293, tv_nsec = 983219454}, st_mtim = {tv_sec = 1560165082, tv_nsec = 861178334}, st_ctim = {tv_sec = 1560165082, tv_nsec = 861178334}, __unused4 = 0, __unused5 = 0} __FUNCTION__ = "main"

Modify DMQ 200OK in on_reply route
by jenus＠cyberchaos.nl 18 Jun '19

18 Jun '19

Hi all, I'm trying to run a kamailio DMQ node inside a docker container. All works fine but i have one issue with DMQ. Since the kamailio process inside the container is behind a nat i have set the advertise address to the external ip, this works fine for the via headers but DMQ keeps sending the internal interface in the KDMQ notification_peer messages. The external ip is in there as well. Example: SIP/2.0 200 OK Via: SIP/2.0/UDP 10.10.10.13;branch=z9hG4bK2dcb.c6326de2000000000000000000000000.0 To: <sip:notification_peer@10.10.10.94:5060>;tag=616b7acb681ed5e9cbc485b3faa09d62.0a3d From: <sip:notification_peer@10.10.10.13:5060>;tag=e8f29c06c4b85a188f6533f08d60feb6-ff29 CSeq: 10 KDMQ Call-ID: 17042656602ca532-23367(a)x.x.x.x Content-Type: text/plain Server: kamailio (5.1.4 (x86_64/linux)) Content-Length: 222 sip:10.10.10.13:5060;status=active sip:10.10.10.12:5060;status=active sip:10.10.10.92:5060;status=active sip:10.10.10.93:5060;status=active sip:10.10.10.94:5060;status=active <-- entry for container external ip sip:172.17.0.2:5060;status=disabled <-- entry for container internal ip I tried to strip this entry using the replace_body_atonce in the tm:local-request route. This works fine for the KDMQ request, but when i try to remove the same line from 200OK responses that are send out as a response to incomming KDMQ messages this seems to fail. I use the following code: # Working code (for outgoing KDMQ requests): event_route [tm:local-request] { if(is_method("KDMQ") && $rU == "notification_peer") replace_body_atonce("sip:172.17.0.*:5060;status=.*", ""); } # Failing code (for 200OK responses): reply_route { xlog("L_ALERT", "REPLY: Sending out reply, tU is $tU rs is $rs\n"); if ($rs == "200" && $tU == "notification_peer") { replace_body_atonce("sip:172.17.0.*:5060;status=.*", ""); } } I'm running kamailio 5.1.4. Is there a way to strip a line from the body of a local generated 200OK response? Or is there a way to avoid that DMQ inserts the internal container ip in the first place. Thanks, Jan Hazenberg

Rabbitmq module blocks sip request
by Denys Pozniak 18 Jun '19

18 Jun '19

Hello! I use rabbitmq module to get destination IP for the next call routing, but this module blocks sip request in case of RabbitMQ server is unreachable (timeout_sec/usec does not run out here). - Is there any solution to avoid such behavior and force function rabbitmq_publish_consume() to return an error code and continue script execution? - Is this connected with the nature of rabbitmq-c client? ("Currently librabbitmq offers no async API, but sync API, with a timeout.") -- BR, Denys Pozniak

Forward calls between kamailio registrar nodes (dmq + dmq_usrloc)

Hello! I am developing setup with several kamailio nodes as registrar cluster (dmq + dmq_usrloc). Location sync works, I see locations of both servers on every server. Is there any standard approach to redirect call between nodes except replacing of $ru?

Authenticating xhttp request
by Olli Attila 18 Jun '19

18 Jun '19

Hello, I have this xhttp event_route on Kamailio that I am using to signal the proxy to reload dialplans and htable when necessary: event_route[xhttp:request] { if(src_ip!=127.0.0.1) { xhttp_reply("403", "Forbidden", "text/html", "<html><body>Not allowed from $si</body></html>"); exit; } if ($hu =~ "^/RPC") { jsonrpc_dispatch(); } else { xhttp_reply("200", "OK", "text/html", "<html><body>Wrong URL $hu</body></html>"); } return; } Now instead of returning 403 forbidden for requests coming from other src_ip than proxy itsef, I would like to authenticate the http request via proxy database. How can this be done if possible? Cheers, Olli

dispatcher and TLS targets
by Karsten Horsmann 17 Jun '19

Hi all, i try to configure an SBC OS config [1] based kamailio 5.2.3 [2] with dispatcher and rtpengine. I used transport=tcp to see the plain traffic and then switched to TLS (with tls.cfg, valid certificate and stuff). After starting up, the Target is marked as "down". Due the encryption its hard to debug that. Any hints? Did i made an mistake in the configuration? TLS calls from the target to my kamailio proxy works. So its "half broken" :) at the moment.

Dispatcher's probing malfunction
by Duarte Rocha 17 Jun '19

17 Jun '19

Greetings, I have some questions about dispatcher's probing mechanics : 1 - In my SBC i have 26 gateways being probed. However, if i do a SIP capture no more than 16 gateways are probed each minute. Some gateways are always probed, others only once in a while. 2 - I have two SBC working in a pair with DB being replicated and with HA IPs. That being said i configure one NAP twice, each configuration with one HA socket. Is this configuration supported? I get very weird behaviours when i configure it like this. Best Regards, Duarte Rocha

Querying in-memory location table (dmq_usrloc)
by Gholamreza Sabery 16 Jun '19

16 Jun '19

I am using dmq_usrloc, to replicate user locations across multiple Kamailio instances. Everything works fine. The problem occurs when a user on Kam1 wants to call a user on Kam2. How can I query the in-memory location table to see where the user is registered? PS: I use a Path header to specify the server that each user is registered on.

15 Jun '19

Hi all, According to this SO question <https://stackoverflow.com/questions/32519551/kamailio-concurrent-calls-afte…> I tried to forward received message to multiple destinations with the following Lua script. But in the second UA I got duplicate Via header. Here is the Lua script: ```Lua KSR.forward_uri("sip:ali@192.168.1.50:7080;transport=UDP"); KSR.forward_uri("sip:tes@192.168.1.50:9080;transport=UDP"); ``` And here is the received Via headers is `tes` UA: ``` Via: SIP/2.0/UDP 192.168.1.21;branch=z9hG4bKbe8c.953ed42f0bcc438c6991121d3483010b.0 Via: SIP/2.0/UDP 192.168.1.21;branch=z9hG4bKbe8c.953ed42f0bcc438c6991121d3483010b.0 Via: SIP/2.0/UDP 10.189.219.4:5060 ;rport=5060;rport=5060;branch=z9hG4bK-4177-1-2 ``` Would you please help me to forward message to multiple destination without duplicate Via headers? Regards, Ali

I understand, to get the cdr you should have created the dialog before replying.

Getting which timer has expired
by Igor Olhovskiy 14 Jun '19

14 Jun '19

Hi! Is there any way to get which timer on transaction actually expired? Scenario is following: INVITE - 180 - 200 OK - (restransmissions 250 msec starts) - pause 15 sec - ACK. In INVITE i'm setting t_on_reply("MY_REPLY") But in around 10 sec after first 200 OK (and 12 sec after INVITE) I'm getting in logs DEBUG: tm [h_table.c:133]: free_cell_helper(): freeing transaction 0x7fb632d77090 from timer.c:689 and on next 200 OK I'm never getting into onreply_route[MY_REPLY] again. Nowhere in the code or config I have explicit set any of timers with 10 or 12 seconds value. Most of them are default. So, can I somehow get which timer expired exactly? PS: If any, pause in 15 sec for a reason to emulate this issue. Regards, Igor

Hello, I am new to Kamailio and I am using Kamailio 5.2. When trying to the load the XHTTP module, event route not found error is thrown and XHTTP is module is not getting loaded. I am trying to use JSONRPC module through HTTP transport for RPC calls. Using XMLRPC, things work fine. DEBUG: <core> [core/sr_module.c:896]: init_mod(): xhttp ERROR: xhttp [xhttp_mod.c:136]: mod_init(): failed to find event_route[xhttp:request] ERROR: <core> [core/sr_module.c:898]: init_mod(): Error while initializing module xhttp (/usr/lib/kamailio/modules/xhttp.so) ERROR: error while initializing modules I have added below to Kamailio.cfg file: loadmodule "xhttp.so" event_route[xhttp:request] { if(src_ip!=127.0.0.1) { xhttp_reply("403", "Forbidden", "text/html", "<html><body>Not allowed from $si</body></html>"); exit; } if ($hu =~ "^/RPC") { jsonrpc_dispatch(); } else { xhttp_reply("200", "OK", "text/html", "<html><body>Wrong URL $hu</body></html>"); } return; } Any help in this regard.

S-CSCF replies “Forbidden - Domain not served”
by Bao, Yin 13 Jun '19

13 Jun '19

We have configured Kamailio IMS (P, I, S-CSCF) to use a single realm with the same NETWORKNAME and trying to make a call between bob and alice. We are getting S-CSCF replies “Forbidden – Domain not served” in two scenarios: 1. When bob calls alice, the INVITE went from P->S->I->S and the destination S-CSCF responded this error 2. During SIP registration in responding to SUBSCRIBE (endpoint still can register even with this reply, so we proceeded with making call) In quick search we found that in scscf/kamailio.cfg route{ } implementation there is a case when this error is generated: # Terminating if (uri == myself || uri =~ "tel:.*") { if (!term_impu_registered("location")) { xlog("L_DBG", "We need to do an UNREG server SAR assignemnt"); assign_server_unreg("UNREG_SAR_REPLY", "location", "term"); exit; } } else { sl_send_reply("403","Forbidden - Domain not served"); exit(); } route(term); break; What is this error designed for? Also in general are we supposed to rework the routing code in Kamailio.cfg (P, S, I-CSCF)? Thanks for any suggestions in advance. Yin
