handle_ruri_alias() and multiple aliases

by Denys Pozniak

Hello! I need help understanding how the *handle_ruri_alias()* function works. *Call-flow:* Upstream operator -> Kamailio Proxy -> Edpoint. The upstream operator in the initial SIP INVITE in the Contact field sends us an alias parameter, in turn, our Kamailio Proxy adds its own too. The Contact after the Proxy looks something like this: *Contact: <sip:10.0.0.115:5060;alias=10.0.0.115~5060~1;alias=3.3.3.3~5060~1>* When the Endpoint sends us a SIP BYE, then the *handle_ruri_alias()* absorbs not the last alias, but the first one, and this leads to the incorrect formation of a $du. The RURI after the Proxy looks something like this: *Request-Line: BYE sip:10.0.0.115:5060;alias=3.3.3.3~5060~1 SIP/2.0* The first thing that comes to mind is a modification of the original Contact field with storing it's within a dialogue ... Is it possible to elegantly solve this problem? -- BR, Denys Pozniak

kamailio 5.4.5 crash after dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg

by Trevor Hemsley

Hi We've seen a few occurrences of this crash since we implemented kamailio 5.4.5 for our inbound call traffic. Preceding the crash we always get a message in the logs about "dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg" and whenever we see that message, we get the crash. Jun 1 10:12:14 thissystem /usr/sbin/kamailio[20001]: CRITICAL: {2 1 INVITE 6787142-3831531134-1330894187(a)some.telco.domain} dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg 0x7fae153d3cf0 [3973:6059] with clid '82608924-3831089984-1833452161(a)some.telco.domain' and tags '3831089984-684203260' '' The crash happens on line 879 of https://github.com/kamailio/kamailio/blob/master/src/modules/dialog/dlg_db_… SET_STR_VALUE(values+7, cell->bind_addr[DLG_CALLER_LEG]->sock_str); Looking at gdb, I see that cell->bind_addr[DLG_CALLER_LEG] == 0 so trying to use it results in the segfault. I have thought about patching that to check for bind_addr being set and bypassing that line if not but I do not think it's the right fix though it probably would avoid the current crash (and do odd things later instead!). I did check that everything else in that function that uses DLG_CALLER_LEG is set correctly and it appears that it is - or at least if not correctly then they are at least set! The "bogus event 2 in state 5" message is coming out from line 1143 in src/modules/ims_dialog/dlg_hash.c case DLG_EVENT_RPL1xx: switch (dlg->state) { case DLG_STATE_UNCONFIRMED: case DLG_STATE_EARLY: dlg->state = DLG_STATE_EARLY; break; default: log_next_state_dlg(event, dlg); } break; (I didn't really understand why it would set dlg->state = DLG_STATE_EARLY if it's already DLG_STATE_EARLY but...) I have a couple of core dumps of this from the last day or two - usually seems to crash at least once a week on our pair of kamailio inbound servers. If there's any more info I can provide to help fix this properly rather than my proposed bodge then feel free to ask.

UAC module register originating from private interface on server

by Jonathan Hunter

Hi, I am working with the UAC module and trying to register with providers, and can see that kamailio keeps sending the REGISTER from the private IP address socket on the server (eth0). Is it possible to set the default socket or send socket for the REGISTER message that gets sent out via kamailio? I am running version 4.4.7. I notice SIP OPTIONS are being sent out from the public IP address (eth1) on the server (as I have set socket in dispatcher) and was hoping for same behaviour with uac module. Please can anyone advise? Many thanks Jon Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10

STIR/SHAKEN tests

by David Villasmil

Hello guys, I want to test secsipid, but i don't yet have the certificate. So i thought i'd create a cert like: openssl req -new -newkey rsa:4096 -nodes -keyout snakeoil.key -out snakeoil.csr openssl x509 -req -sha256 -days 365 -in snakeoil.csr -signkey snakeoil.key -out snakeoil.pem Then i'm simply doing: $var(rc) = secsipid_add_identity("$fU", "$rU", "A", "", " https://somedomain.com/stir/$rd/cert.pem <https://kamailio.org/stir/$rd/cert.pem>", "/etc/kamailio/snakeoil.pem"); if ( $var(rc) ) { xlog("L_ERR", "[STIR/SHAKEN][$ci] Shaken authentication added (SIP Identity Header created)\n"); } else { xlog("L_ERR", "[STIR/SHAKEN][$ci] Failed\n"); } But no matter what i do it silently fails: INVITE d54c2919-39b6-123a-95a7-0e29a5289b8d} <script>: [STIR/SHAKEN][d54c2919-39b6-123a-95a7-0e29a5289b8d] Failed I have debug on 6, but i don't get more info regarding the error. Any ideas? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Possible memory leak?

by George Diamantopoulos

Hello all, I've been experiencing memory exhaustion (all 8GiB of it) on hosts running kamailio for quite some time now while on the 5.4.x train. I can't really say about previous versions, because the setup was quite different back when I was using those. After about 2 days of operation, RAM is exhausted and kamailio is killed by the kernel OOM which frees up memory again. Restarting kamailio via systemd will also free up most memory. I can't seem to find what is using it up, so I'm guessing there might be a memory leak, but I'm not 100% sure so I thought I'd ask the list for opinions. I'm including the output of kamcmd pkg and shm stats and kamctl stats here. My take on those is that there's nothing to show where all this RAM is going. Kamailio version is 5.4.5+bpo10 on debian buster and is started with '-P /run/kamailio/kamailio.pid -f /etc/kamailio/kamailio.cfg -m 2048 -M 16' (51 processes total).

IMS IPSec does use UDP socket?

by H Yavari

Hi to all, I am interested in the implementation of IPsec module. When I run Kamailio, it is creating processes based on the below formulate: UDP children * IPSEC_MAX_CONN * interfaces (v4 and v6) + (TCP+UD) processes for each interface. For example: children = 16tcp_children=16 IPSEC_MAX_CONN = 25and two interface : IPv6 and V4 Kamailio process count = (16 * 25 * 2 ) + 16 + 16 = 832 But why IPsec module is listening to UDP not TCP? this is an internal connection? Thank you. Regards,Hossein

SDP body, add maxptime attribut

by Victor Velo

Hello, I would like to add the maxptime attribut to the sdp body. How and where should I do insertion? This kamailio is also using RTPEngine, so is it better to do the insertion using RTPEngine? And the source of the SDP is actually FreeSwitch :), maybe there to tweak? Of course, I don't know either way of doing it so please advise. Thanks, Victor

New MariaDB server "limiting" Kamailio CPS

by Stephen Lokker

Good afternoon All, Im hoping for some advise or direction with the below. We are running a Kamailio SBC used for high call volumes and recently decided to upgrade the Database servers as the existing servers were struggling. Both the old and new databases are using MariaDB(version details all below), the problem we face is that since migrating to the new database there appears to a limitation to the amount of DB connections that can be processed or accepted. The SBC functions normally until the CPS starts to exceed around 100cps at which point the SBC stops responding to invites(in bursts which resembles flood prevention). We have checked both the Kamailio logs and the MySQL logs on the DB, both log files have no indication of errors that would cause the problem experienced(the logs attached are seen when the SBC is cut back to use the old DB, not sure they are related to the fault), the connections/processes in mysql do not drastically increase or get stuck either. The fault points to a db connection limit of some kind but all users have no limitations set. If anyone has experienced a similar problem or has any advise it would be greatly appreciated. Some info on the Kamialio and DB versions New DB root@voice-jhb-db01:~# mysql --version mysql Ver 15.1 Distrib 10.3.27-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2 Old DB [root@isadb01 ~]# mysql --version mysql Ver 15.1 Distrib 10.0.36-MariaDB, for Linux (x86_64) using readline 5.1 Kamailio SBC [root@sbc01 ~]# kamailio -v version: kamailio 5.1.4 (x86_64/linux) Kind regards, Stephen Voice Engineer Tel: 2404 Fax: 3468 Email:
