slow timer too slow: overflow
by Denys Pozniak 05 Sep '22

05 Sep '22

Hello! After some time, Kamailio stops processing incoming messages. slow timer too slow: overflow messages appear in the log (I suspect that the problem is related to the rtimer module) Aug 29 14:19:17 kamailio[11320]: 2(11320) ERROR: {1 10 OPTIONS 2b45547f33f5203f-4091(a)10.10.10.10} <core> [core/mem/q_malloc.c:430]: qm_malloc(): qm_malloc(0x7f163b9f9010, 960) called from core: core/rvalue.c: rval_new_empty(246), module: core; Free fragment> Aug 29 14:19:17 kamailio[11320]: 2(11320) ERROR: {1 10 OPTIONS 2b45547f33f5203f-4091(a)10.10.10.10} <core> [core/rvalue.c:253]: rval_new_empty(): could not allocate private memory from pkg pool Aug 29 14:19:17 kamailio[11330]: 12(11330) WARNING: <core> [core/timer.c:936]: timer_handler(): slow timer too slow: overflow (62671 - 61648 = 1023) Aug 29 14:19:17 kamailio[11320]: 2(11320) ERROR: {1 10 OPTIONS 34618af41c3866bc-16408(a)10.10.10.20} <core> [core/mem/q_malloc.c:297]: qm_find_free(): qm_find_free(0x7f163b9f9010, 960); Free fragment not found!

HTTP client and HTTP/2 support
by Alex Balashov 01 Sep '22

Hi, I wasn’t able to find an answer on the list previously, nor any trail of breadcrumbs in the docs: do any of the existing HTTP client modules support HTTP/2? — Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Disabling video rtp proxing
by mayamatakeshi 31 Aug '22

31 Aug '22

Hi, I'm using rtpengine for RTP proxying with kamailio. I use it just for audio. But eventually some terminal reinvites offering video. I don't want to refuse the request but just disable RTP proxying for video as my employer has limited bandwidth and want to reserve it only for audio. So I checked the rtpengine module documentation but it seems there is no way to restrict RTP proxying to be performed only for m=audio. I tried some things like replace_body("^m=video [0-9]+", "m=video 0"); and subst_body('/^m=video [0-9]+ /m=video 0 /'); and msg_apply_changes(); but still the RTP proxying for video is set up. Any hints on how to solve this?

Intermittent delays relaying BYE (up to 1s)
by Lewis Hutchinson 31 Aug '22

31 Aug '22

Ok so making progress but still a little confused, hopefully this forum can shed some light on this behaviour. Using the hints provided (thanks all so far) and the latency logging from the cookbook I have managed to isolate the issue down to RTPengine introducing the delay. INFO: app_python3 [apy_kemi.c:1820]: sr_apy_kemi_exec_func(): alert - action KSR.rtpengine.rtpengine_manage(...) took too long [1003089 ms] (file:(null) func:(null) line:252) What is confusing is, I don't believe this block should be being called. when the BYE is triggered, it routes to ksr_route_withindlg # handle requests within SIP dialogs if self.ksr_route_withindlg(msg)==-255 : return 1 from within the ksr_route_withindlg a check is done to see if any RTPengine work needs doing # Handle requests within SIP dialogs def ksr_route_withindlg(self, msg): if KSR.siputils.has_totag()<0 : return 1 # RTPEngine handling for UPDATES & reINVITES with sdp if self.ksr_route_rtpengine(msg) == -255: return 1 RTPengine is configured in a way to step in whenever there is an SDP present based on Content-Type: application/sdp # RTPengine handle anything with SDP def ksr_route_rtpengine(self, msg): if KSR.textops.has_body_type("application/sdp"): KSR.rtpengine.rtpengine_manage( "RTP/AVP replace-session-connection replace-origin ICE=remove") return 1 What I can understand is why is this being called and erroring introducing the delay when there is no Content-Type: application/sdp in a BYE ??? As a quick fix I have put this in which stops the problem (I am sure there is better ways to handle this but for now this works in a DEV environment) def ksr_route_rtpengine(self, msg): if KSR.is_BYE(): return 1 if KSR.textops.has_body_type("application/sdp"): KSR.rtpengine.rtpengine_manage( "RTP/AVP replace-session-connection replace-origin ICE=remove") return 1 Can anyone see why this would occur? Why is sr_apy_kemi_exec_func(): alert - action KSR.rtpengine.rtpengine_manage(...) even being called for this BYE ? when there is no Content-Type: application/sdp Lewis

31 Aug '22

Hi, I'm trying to configure kamailio to register users over websockets, but i am not able to find any working configuration around, am new to kamailio. as far as i understand now, xhttp will handle the HTTP GET requests, i am not sure how to configure xhttp port number, cannot find parameters in the module manual, i found multiple sample configs but none of them is working, am using JsSip client. if someone can guide me with a link to a working config and that i can start from.

app_python module load error in 5.6
by Stefan-Cristian Mititelu 30 Aug '22

30 Aug '22

Hello, I am trying to load app_python.so module in kamailio 5.6 and I am getting the following error, under debian bullseye: ERROR: <core> [core/sr_module.c:573]: load_module(): could not open module </usr/lib/x86_64-linux-gnu/kamailio/modules/app_python.so>: /usr/lib/x86_64-linux-gnu/kamailio/modules/app_python.so: undefined symbol: LOG_ The app_python.so file exists, under that path. Same ERROR for app_python3.so. I have tried updating some modules's Makefile LDFLAGS but didn't work so far; still searching. Any ideas? Thank you, Stefan

Core variable with from userinfo value of sip uri
by Denys Pozniak 30 Aug '22

30 Aug '22

Hello! It was accidentally noticed that the variable $fU gets the user part of userinfo SIP URI (although it is logical and described in the document RFC2543). I got message below and my spam filter based on $fU passed it inside the network, as $fU was test From: <sip:test:test@1.1.1.1>;tag=123456 Sure I can filter it through a regular expression, but maybe it's worth adding another core variable with the userinfo value? SIP-URL = "sip:" [ userinfo "@" ] hostport url-parameters [ headers ] userinfo = user [ ":" password ] -- BR, Denys Pozniak

Re: [SR-Users] kamailio Trunk authentication

Hello, For non-commercial support please address our sr-users list (added to CC). Please look at the uac module, there a function uac_auth() for this particular scenario with example cfg. https://kamailio.org/docs/modules/5.5.x/modules/uac.html#uac.f.uac_auth Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: Keshav Kaushik <kdkaushik(a)gmail.com> Sent: Sunday, August 28, 2022 1:34 PM To: Henning Westerholt <hw(a)gilawa.com> Subject: kamailio Trunk authentication Respected Sir, I am new to kamailio so not very familiar with config PV’s and transformations etc. I have successfully authenticated the Twilio SIP phone via ACL. But I also willing to authenticate the Twilio SIP via username and password. For doing this I plan to modify the “proxy-authentication” header as blow: if (is_present_hf("Proxy-Authorization")) { $nonc=$sel(proxy-authorization.nonce);// not working $has="kamailio:$ar:SdE-----------ADVpa"; $ha1=$(has{s.md5}); hat="$aa:$adu"; $ha2=$(hat{s.md5}); $resp="$HA1:$nonc:$HA2"; append_hf('Proxy-Authorization: Digest username="kamailio", realm="$ar", nonce="$nonc", uri="sip:+1650ZZZZZZ@XX.YY.7.195", response="$(resp{s.md5})"'); } remove_hf("Proxy-Authorization");// remove original header When I save the config file and restart kamailio, it does not start, may be due to some error in code. Can you please help in authentication of a SIP trunk using user/passowrd. Thanks in advance Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows
