t_relay changing source IP?
by Brooks Bridges 27 Oct '21

27 Oct '21

So we have a box that's bound to all interfaces on the server, and one specific IP address (that is an HA IP), and I've run into a bit of an odd behavior that I cannot explain. For 99.9999% of our traffic, the invites come into the HA IP, and then are forwareded out the HA IP to an SBC for further processing. In a very rare instance however, I have found that there is an invite coming in the HA IP, and for some unknown reason it gets forwarded out the *interface* ip instead of the HA IP. For example: Working: 1.2.3.4 -- invite --> 9.8.7.6 (ha IP) -- invite --> 5.6.7.8 (sbc) Non working: 1.2.3.4 -- invite --> 9.8.7.6 (ha IP) *something happens here* 9.8.7.5 (interface IP) -- invite --> 5.6.7.8 (sbc) I've been through tm, tmx, and the incoming invite of a working and non working request with a fine toothed comb and I cannot for the life of me explain this behavior.

Use constants in attrs column of the dispatcher module
by Markus Bönke 27 Oct '21

27 Oct '21

Hello all, I’ve a question regarding the dispatcher module. So far we use on every server a separate database table, where the attribute column is set to the local internal or external socket like "socket=udp:192.168.1.70:5060“ or socket=udp:80.239.xxx.xxx:5060. Is there a way to use constants here like socket=udp:IPADDR_INTERN:5060 or socket=udp:IPADDR_EXTERN:5060 which are replaced when the data is loaded from the DB? Thanks and regards Markus

No "child_destroy" export ?
by Chaigneau, Nicolas 26 Oct '21

26 Oct '21

Hello, I have a module, for which I need to perform some processing in the children processes when Kamailio is being stopped. I've looked at the "struct module_export", in which I see "mod_init", "child_init", "mod_destroy"... but no "child_destroy". :/ Is there a way to achieve this ? Thanks for your help.

Kamailio/Asterisk Realtime issues
by Hayden Ryan 26 Oct '21

26 Oct '21

Hi all, I have Kamailio and Asterisk set up in a realtime configuration, like this: https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb In my setup, Kamailio forwards all REGISTER requests to Asterisk, and Asterisk authenticates them. I have a single peer in sip.conf pointing towards the Kamailio server, as type=peer Each user in the Asterisk database is set to type=user, as when they are set to anything else (or blank), incoming calls from Kamailio to Asterisk display the name of the most recent extension to register. Is there something wrong with my setup here? What I am trying to do is to get MWI working. SUBSCRIBEs for MWI are forwarded to and handled by Asterisk correctly. Yet the MWI state on the handset is incorrect, as I believe it is sending the latest MWI update to the most recently registered extension. Any suggestions would be much appreciated. I assume I'm doing this the wrong way and shouldn't be forwarding any REGISTERs to Asterisk and should be handling authentication in Kamailio itself? But that seems incompatible with the realtime configuration guides I've seen. Thank you, Hayden

Info: risk of failure by upgrading to MariaDB 10.3.31
by Daniel-Constantin Mierla 25 Oct '21

25 Oct '21

Hello, not strictly related to Kamailio, but I know a large number of its deployments run with MariaDB. Be aware of a (pretty high) risk of failure after upgrading MariaDB server to v10.3.31, which comes now on Debian 10 via the usual apt update+upgrade. I was hit on one the servers I upgraded recently, first one worked fine, the 2nd failed to start MariaDB service after upgrade - there is a bug report about it: * https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1823336.h… Downgrading MariaDB seems to be the right solution for now, specially if you didn't do a backup just before upgrade. Don't try other tricks without a fresh backup, data files can be damaged. If you have a fresh backup, there seems to be a solution by deleting database files to start with a clean set and then restore from backup with sql statements. FreeBSD has a similar bug report, so doesn't seem to be only Debian, could be other Linux distros as well. Even with fresh backups, plan for a longer maintenance time frame than usual.

T_req(pv) not accessible in dialog event route in v5.5.2
by Joel Serrano 23 Oct '21

23 Oct '21

Hello, I'm in the process of updating some servers that are running Kam v5.1.4 to v5.5.2. After the upgrade I've noticed that I've lost some custom metrics that we have defined via config-script. Snippet of the relevant config: event_route[dialog:start] { # Gather metrics regarding source IP xlog("L_WARN", "[DLG] - Checking country for ($si | $T_req($si)) - START\n"); if (geoip2_match("$T_req($si)", "src")) { # Country found ... } xlog("L_WARN", "[DLG] - Checking country for ($si | $T_req($si)) - END\n"); } NOTE: xlog lines added for debugging, they normally are not there. In version 5.1.4 in the logs I see: Oct 21 15:55:47 13cn3 sbc[22606]: WARNING: <script>: [DLG] - Checking country for (A.B.C.D | 186.185.186.7) - START Oct 21 15:55:47 13cn3 sbc[22606]: WARNING: <script>: [DLG] - Checking country for (A.B.C.D | 186.185.186.7) - END The same config, on v5.5.2 is returning: Oct 21 15:57:08 sbc0504 sbc[22606]: WARNING: <script>: [DLG] - Checking country for (A.B.C.D | <null>) - START Oct 21 15:57:08 sbc0504 sbc[22606]: WARNING: <script>: [DLG] - Checking country for (A.B.C.D | <null>) - END After enabling debug logs I see: WARNING: <script>: [DLG] - Checking country for (198.1.55.124 | <null>) - START *DEBUG: tmx [t_var.c:309]: pv_get_t_var_req(): used in unsupported route block - type 64*DEBUG: geoip2 [geoip2_pv.c:488]: geoip2_update_pv(): attempt to match: <null> DEBUG: geoip2 [geoip2_pv.c:491]: geoip2_update_pv(): no match for: <null> Did something change in the tmx module that could affect $T_req(pv) being accessible in the dialog:start event_route? Any alternatives to get the source IP of the request (not the reply) in the dialog:start event_route? Let me know if you prefer that I open a ticket for this in GH. Thanks, Joel.
