Hi Guys, After enabling TLS i am getting following error in Kamailio 5.1 /usr/sbin/kamailio[2214]: ERROR: tls [tls_util.h:42]: tls_err_ret(): load_cert:error:20074002:BIO routines:file_ctrl:system lib /usr/sbin/kamailio[2214]: ERROR: tls [tls_util.h:42]: tls_err_ret(): load_cert:error:140DC002:SSL routines:use_certificate_chain_file:system lib /usr/sbin/kamailio[2214]: ERROR: <core> [core/sr_module.c:940]: init_mod_child(): error while initializing module tls (/usr/lib/x86_64-linux-gnu/kamailio/modules/tls.so) (idx: 0 rank: -127 desc: [main]) My tls.conf is as follows: [server:default] method = TLSv1+ verify_certificate = no require_certificate = no private_key = /etc/kamailio/keys/my.key.pem certificate = /etc/kamailio/keys/my.crt.pem #ca_list = /etc/kamailio/tls/cacert.pem #crl = /etc/kamailio/tls/crl.pem # This is the default client domain, settings # in this domain will be used for all outgoing # TLS connections that do not match any other # client domain in this configuration file. # We require that servers present valid certificate. # [client:default] #method = TLSv1 verify_certificate = yes require_certificate = yes Please hep me to understand and fix the issue.

crash at 480 reply to INVITE

Kamailio 5.2 crashed when it received 480 reply to INVITE. Below is backtrace from the core file. The crash happens in t_reply.c on the last line of this block: uac=&t->uac[branch]; LM_DBG("org. status uas=%d, uac[%d]=%d local=%d is_invite=%d)\n", t->uas.status, branch, uac->last_received, is_local(t), is_invite(t)); last_uac_status=uac->last_received; Earlier it was checked that the transaction was found. Its uac[0] seems to be broken. -- Juha ----------------------------------------- Program terminated with signal SIGSEGV, Segmentation fault. #0_ 0x00007f1073e234c3 in reply_received (p_msg=0x7f1076b605f0) at t_reply.c:2240 2240_ _ _ t_reply.c: No such file or directory.

http_event have errors with exec_avp
by logosvlad＠gmail.com 02 Mar '19

02 Mar '19

Hi there! we have an issue, and it's similar to reported in this thread: http://sip-router.1086192.n5.nabble.com/exec-warning-td165448.html We use kamailio 5.0.6. When we call route from http_event by url reguest (code is below) event_route[xhttp:request] { set_reply_close(); set_reply_no_connect(); if ($(hu{url.path}) ==”update”) { route(DO_SMTH); xhttp_reply("200", "OK”, "", ""); } route[DO_SMTH] { exec_avp(“/usr/bin/who”,”$avp(s:user_)”); } we got errors exec like these: Mar 1 10:51:05 test kamailio[21035]: WARNING: exec [exec_hf.c:464]: append_fixed_vars(): uri not parsed Mar 1 10:51:05 test kamailio[21035]: WARNING: exec [exec_hf.c:482]: append_fixed_vars(): orig URI not parsed Mar 1 10:51:05 test kamailio[21035]: ERROR: exec [../../core/char_msg_val.h:51]: char_msg_val(): can't calculate char_value due to a parsing error Mar 1 10:51:05 test kamailio[21035]: WARNING: exec [exec_hf.c:492]: append_fixed_vars(): no tid can be determined Mar 1 10:51:05 test kamailio[21035]: ERROR: exec [exec_hf.c:504]: append_fixed_vars(): no to-tag But when we call route(DO_SMTH) from request_route - there are no such errors We think that it is something related to the nature of event_routes, anything can be done with this? Should I create an issue on github? thanks for insights and ideas

Re: [SR-Users] How to Absorb First Leg Re-Invites when no Response from Second Leg Invites
by JR Richardson 02 Mar '19

Yes, retransmissions of initial INVITE from Carrier. Makes perfect sense, I understand now. Thanks Gentlemen! JR Reinvites are in-dialog requests; they would only be sent within the context of an established dialog (2xx response, end-to-end ACK, the whole works). Perhaps what you are referring to is not reinvites but retransmissions of the initial INVITE? If so, have a look at this option: https://kamailio.org/docs/modules/5.2.x/modules/tm.html#tm.p.cancel_b_method in concert with something like this: failure_route[...] { if(t_is_canceled()) exit; # The scenario you're after. if(t_branch_timeout()) { t_reply("503", "Service Unavailable"); exit; } } -- Alex

Hi, I am looking for a option to execute multiple command via JSONRPCS or XMLRPC. To avoid multiple tCP connections . eg: I have multiple kamailio load balancer server running, need to update the dispatcher record in a single command. Regards, Vimalesh S

How to Absorb First Leg Re-Invites when no Response from Second Leg Invites
by JR Richardson 02 Mar '19

02 Mar '19

Hi All, My mind is not right on this one, need a pointer. Here is the simple scenario: Carrier><kamailio proxy><end device The end device is a static IP, the proxy dips database and knows where to send numbers destined for the end device, but if there is no response from the end device (it's off-line), how do I time-out the transaction and send a 503 'Service Unavailable' back to the first leg for the carrier to stop re-invites? I assume I need a new [FAIL_TWO] route that handles this event. Thanks. JR -- JR Richardson Engineering for the Masses Chasing the Azeotrope

i have setup asterisk/rtpproxy/kamailio following the guide in https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb and later NAT traversal with rtpproxy as i understand in simple we must have: phone/caller-->[-->rtpproxy->kamailio->asterisk->kamailio->rtpproxy -]->phone/dest But when you make a call between two phones, there is no sound... ...to make it work and get sound have to open the ports (range 10000 to 30000 udp) in the asterisk exposing them to the public ip whre its the kamailio and rtpproxy. We configured kamailio with rtpproxy (also tried with rtpengine), and when I configure Asterisk and Kamailio in "real time" mode, everything goes well, the extensions are registered, the authentication is in the asterisk side (table sipusers requires ignore the version check parameter if you use kamailio 5+) etc etc .. but there's no sound, we have: kamailio.bindip="10.10.1.1" desc "kamailio.bindip" kamailio.bindport=5060 desc "kamailio.bindport" asterisk.bindip="10.10.1.2" desc "asterisk.bindip" asterisk.bindport=5060 desc "asterisk.bindport" listen=udp:10.10.1.1:5060 advertise 200.1.1.1:5060 at rtpproxy we have: /usr/bin/rtpproxy -s unix:/var/run/rtpproxy/rtpproxy.sock -u kamailio -p /var/run/rtpproxy/rtpproxy.pid -l 10.10.1.1 -A 200.1.1.1 -F -m 10000 -M 30000 why we need to make asterisk open the ports directly to the publlic ip? N]OTE: the public ip are not a real interface in the kamailio/rtppropxy machine, are provided by the service AWS at amazon! a NAT kind i guess!

Kamailio behind NAT or With Public IP - Which one is highly recommended
by Pintu Lohar 28 Feb '19

28 Feb '19

Hi Everyone, Which one among the below option is highly recommended for setting up Kamailio (for production) 1. Kamailio behind NAT *or* 2. Setting up Kamailio using public IP? are there any disadvantages if we setup Kamailio behind NAT and use advertise option in listen parameters? We have tested both the options, and both the options work great for us( a. Kamailio behind NAT with advertising in listen parameters b.Kamailio setup with public IP). So wondering which one is best and highly recommended? Some extra info : 1. We use TLS 2. Using coturn for media Thanks Pintu

Problem with ghost dialogs
by Cyrille Demaret 28 Feb '19

28 Feb '19

Hi, I'm running Kamailio 5.1.4 and I have some problem with some random dialogs sometimes staying in early state and never ends until I restart Kamailio. According to the init_ts, this dialog is there since 11/01/2019. * Do you have an idea how I can diagnose this problem? * Is there a way to kill these dialogs? I have tried with "dlg.end_dlg" but It seems it's not possible to kill dialogs in early states. { h_entry: 3382 h_id: 4069 call-id: d6e6de79-7d55-486f-889f-01b05c003411 from_uri: sip:0037xxxxxxxxxxx@mydomain.com to_uri: sip:1234@mydomain.com state: 2 start_ts: 0 init_ts: 1547195739 timeout: 0 lifetime: 43200 dflags: 1536 sflags: 0 iflags: 0 caller: { tag: a909d6fa-cee9-44ac-ad76-3697fcd5cb0e contact: sip:asterisk@192.168.102.20:5080;alias=192.168.102.20~5080~1 cseq: 7362 route_set: socket: udp:192.168.102.10:5060 } callee: { tag: contact: cseq: route_set: socket: } profiles: { { caller: sip:0037xxxxxxxxxxx@mydomain.com } { callee: sip:1234@mydomain.com } } variables: { } } Thank you for your help.

Masking Contact Header
by Duarte Rocha 28 Feb '19

28 Feb '19

Greetings, Is there an automated way of masking\encoding\encrypting the Contact header once it goes through a Kamailio proxy and have it restored? I'm using uac_replace_from() and uac_replace_to() for changing these values and having them restored automatically. Is there any tool like this for Contact Header? Cheers

Local Route blocks
by Grant Bagdasarian 28 Feb '19

28 Feb '19

Hi, I noticed some module functions mention "LOCAL_ROUTE", like the Domain module (http://www.kamailio.org/docs/modules/5.2.x/modules/domain.html#domain.f.loo…). I couldn't find anything related to the LOCAL_ROUTE in the docs. What are these used for and how are these declared and used? Regards, Grant CM.com

double_rr issues
by Roman Dissauer 28 Feb '19

28 Feb '19

I’m experiencing issues with kamailio 5.1 in multihomed config: two machines, latest debian stretch, latest kamailio 5.1, exactly same config (verified with diff) both machines have an internal and an external network interface. Only thing different is that they are in different datacenters. on one machine everything works perfect, on outgoning calls rr parameters are added perfectly right: Record-Route: <sip:yy.yy.yy.yy;transport=tcp;r2=on;lr;nat=yes> Record-Route: <sip:xx.xx.xx.xx;transport=tcp;r2=on;lr;nat=yes> where yy.yy.yy.yy is the external ip and xx.xx.xx.xx is the internal IP on the other machine I only get: Record-Route: <sip:xx.xx.xx.xx;transport=tcp;lr;nat=yes> even if I set enable_double_rr to 2 I get: Record-Route: <sip:xx.xx.xx.xx;transport=tcp;r2=on;lr;nat=yes> Record-Route: <sip:xx.xx.xx.xx;transport=tcp;r2=on;lr;nat=yes> I already checked with traceroute that the routing to the destination IP Adresses are going through the external interface. maybe someone has a hint for me. Thank you all in advance! Roman

TLS reload
by Patrick Wakano 27 Feb '19

27 Feb '19

Hi list, I've seen the TLS documentation ( https://www.kamailio.org/docs/modules/5.2.x/modules/tls.html#tls.known_limi…) where it states that TLS specific config reloading is not safe, so for now better don't use it, especially under heavy traffic. This note is there since version 3.0 and in 2013 there was some discussion about it but wthout anything conclusive.... What I would like to know if this is still the case. Is anyone running the TLS reload for certificate renovation for example, or is it better to restart Kamailio? Thanks, Kind regards, Patrick Wakano

SQlite in memory
by Duarte Rocha 27 Feb '19

27 Feb '19

Greetings, I'm trying to use SQlite as my engine in order to improve performance. I would like to have my Database stored in memory for faster access. I see that Kamailio can open the SQlite database as Read-Only, but i can't find a way to open it in memory. Is this possible using Kamailio? What's the best way to do this? Best Regards, Duarte Rocha

auth_ephemeral too noisy
by Juha Heinanen 27 Feb '19

27 Feb '19

I did some tests with auth_ephemeral. When timestamp has expired, I get to syslog Feb 23 03:53:05 char /usr/bin/sip-proxy[31758]: WARNING: auth_ephemeral [authorize.c:205]: autheph_verify_timestamp(): username has expired Feb 23 03:53:05 char /usr/bin/sip-proxy[31758]: ERROR: auth_ephemeral [authorize.c:260]: digest_authenticate(): invalid timestamp in username In my opinion, the WARNING is enough and the ERROR message should be removed. ERROR is when an error happens. There is no error here, just an expired timestamp. -- Juha

Using the avp [*] index with jansson module functions
by Enrico Bandiera 26 Feb '19

26 Feb '19

Hello, I would like to use the [*] index for the avps (to overwrite instead of adding to the stack) when passing the variable to jansson module functions. When trying to do so I get this error: 9(35) ERROR: jansson [jansson_funcs.c:219]: janssonmod_set(): result has json error at line 1: end of file expected near ',' I suppose this is unsupported but maybe I'm doing something wrong, any suggestions? Thanks, Enrico.

bad transport for sips uri?
by David Cunningham 26 Feb '19

Hello all, We're having an issue with Kamailio not processing an ACK and hope someone can help. A PCAP shows that Kamailio is receiving the ACK, and we believe these log messages are directly related to it: Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: tm [ut.h:279]: uri2dst2(): ERROR: uri2dst: bad transport for sips uri: 1 Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: tm [t_fwd.c:1777]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: sl [sl_funcs.c:387]: sl_reply_error(): ERROR: sl_reply_error used: Unresolvable destination (478/SL) The ACK is as follows. It's from telephone 111111 which is using TLS, which Kamailio listens for on port 5061. Does anyone know which URI has the bad transport as per the error above? Might it be the From URI "sips:111111@es8.example.com" because it doesn't specify port 5061? Thank you in advance.

Dialog - Kamailio 5.2
by Nicolas Breuer 25 Feb '19

25 Feb '19

Hello the world, Can you give more informations about the new features of Dialog in K5.2 ? https://www.kamailio.org/w/kamailio-v5-2-0-release-notes/ * ability to load dialog records from database on demand * ability to load dialog records from database if they are not yet in memory cache Indeed in 5.1, restart Kamailio doesn't load the dialog data from database but we can see https://www.kamailio.org/docs/modules/5.1.x/modules/dialog.html#dialog.p.db… there is a function : Set db_skip_load to 1, to skip the loading of dialog data from the database. If on restart, the dialogs are not loaded, what this "db skip load " does ?
