Kamailio/MySQL Module compatibility with MySQL 8.0+

by Pedro Ulhoa

Hello friends. I didn't find about it in the documentation, but I will need to update my database version to MySQL 8.0.32 and I'm using Kamailio version 5.4. I did some quick tests, and I only needed to adjust the user due to the authentication mode, and with that, apparently I had no problems. I would like to know if you are using Kamailio with the latest version of MySQL, if you have had any problems in production, and if it really is safe to upgrade. -- Aviso Legal: Este documento pode conter informações confidenciais e/ou privilegiadas.

What is the best way to return a lot of data via JSONRPC and jansson?

by Benoit Panizzon

Hi Team To offer some diagnose functionality I created an API that returns the location list via JSONRPC But this creates huge variables. Jun 12 09:43:32 prod-cpereg02 kamailio[2174548]: ERROR: <core> [core/pvapi.c:1491]: pv_printf_mode(): no more space for spec value - printed:0 token:8599 buffer:8192 Jun 12 09:43:32 prod-cpereg02 kamailio[2174548]: ERROR: <core> [core/pvapi.c:1503]: pv_printf_mode(): buffer overflow -- increase the buffer size... Already hitting the default limit and not sure this is the right way to go as we will end up with thousands of registrations. What is the best way to return larger ammounts of data out of kamailio? Avoid using the JSONRPC and access the database externally?

Dialog DMQ state after restart

by Calvin E.

Does the dialog module do anything similar to the htable dmq_init_sync behavior? The scenario is restarting the offline member of an HA pair after modifying the script. We're unsure of the state of the replicated dialogs post-restart. Will the standby become aware of the dialogs prior to the restart? In other words, do we need to wait until the pre-restart calls end before we can safely failover? -Calvin E.

Invalid Links

by Brandon Armstead

https://www.kamailio.org/w/kamailio-v5-7-0-release-notes/ article references math module and tls_wolfssl, 2 of the 4 modules mentioned link back to 5.6 (these two) instead of 5.7 resulting in a 404. Respective links should be as follows: math - https://www.kamailio.org/docs/modules/5.7.x/modules/math.html tls_wolfssl - https://www.kamailio.org/docs/modules/5.7.x/modules/tls_wolfssl.html Can we get a correction in the article on WP? Thanks - Brandon

Missing transformations for {val.*}?

by Kaufman

Beginning in 5.6 new {val.*} transformations are documented as being exported by the pv module, however if I try using it Kamailio fails to start. Wondering if maybe it's actually imported by another module and the documentation is wrong or something like that? This configuration in 5.6.3 on Alpine Linux installed from packages: #!KAMAILIO loadmodule "pv" loadmodule "xlog" request_route { xlog("Null val: $(avp(nothing){val.ne})\n"); exit; } Fails to start with the following: 0(114) INFO: <core> [main.c:3055]: main(): processes (at least): 29 - shm size: 67108864 - pkg size: 8388608 0(114) ERROR: <core> [core/pvapi.c:1774]: tr_lookup(): unknown transformation: [val] in [{val.ne}] 0(114) ERROR: <core> [core/pvapi.c:1799]: tr_lookup(): error parsing [{val.ne}] 0(114) ERROR: <core> [core/pvapi.c:1106]: pv_parse_spec2(): bad tr in pvar name "avp" 0(114) ERROR: <core> [core/pvapi.c:1131]: pv_parse_spec2(): invalid parsing in [$(avp(nothing){val.ne})] at (4) 0(114) ERROR: xlog [xlog.c:551]: xdbg_fixup_helper(): wrong format[Null val: $(avp(nothing){val.ne})] 0(114) ERROR: <core> [core/route.c:1169]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:7 Kaufman Sr. VoIP Engineer - BCM One +1.612.735.9309 bkaufman(a)bcmone.com<mailto:bkaufman@bcmone.com> 24 hour client support: +1.855.639.6300 [https://www.bcmone.com/files/bcmone-logo.png]<https://www.bcmone.com/> [https://www.bcmone.com/files/twitter-icon-circle.png] <https://www.facebook.com/bcmonenyc/> [https://www.bcmone.com/files/twitter-icon-circle.png] <https://twitter.com/bcm_one/> [https://www.bcmone.com/files/linkedin-icon-circle.png] <https://www.linkedin.com/company/business-communications-management/> NOTE: This e-mail and any attachments are from BCM One, Inc. and are intended solely for the use and review of the individual(s) to whom it is addressed.

custom mid registrar using kamailio.

by Yuriy Nasida

Hello, https://lists.kamailio.org/pipermail/sr-users/2020-October/110792.html I read this thread very carefully and I think I managed to implement all the steps described by Daniel. Thank you so much for the detailed description. But it looks like I'm stuck on the last step. I can't delete records from htable when an incoming call cannot reach the registered device (e.g., no more internet access, power off at the device). I try to do this from failure route but looks like i kamailio has not access to htable from it. failure_route[INTERNAL_TO_EXTERNAL_FAILURE] { if (t_check_status("408")) { xlog("L_WARN", "$ci|log| hello \n"); xlog("L_WARN", "$ci|log| mid reg token - $sht(mid_reg_token=>$fU::$si::$sp) \n"); } } I do not see xlog message with mid reg token but i see 'hello'. Yes, htable record exists in case i check using: kamcmd htable.dump mid_reg_token Also I need a way to remove registration at the registrar (Freeswitch in my case). This means I need to send api request from kamailio or just run some script that will do this. What is the best way ? module exec ? Please advice, Thanks
