Hello guys, so i'm doing on a failure_route: $var(xgws_in_reply) = $T_rpl($hdr(X-GWs)); which when it’s present on the reply is cool… but when there is NO REPLY, then kamailio sets it to “0”… anyway over this? i only want to know whether it is present on the reply Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Missing transformations for {val.*}?
by Kaufman 03 Jun '23

03 Jun '23

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 01 Jun '23

01 Jun '23

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
