enable topology hiding on one side or dynamic ip in topoh module Contact and Via Header

by Patrick Karton

Hello , im using kamailio with two interfaces external and internal. i need a way either to : * enable topoh hiding only when outgoing interface is external ( mask contact and Via ip only when ougoing interface is external * or if it is not possible to enable it only in one direction.i want to know how to configure dynamic(for example in xavp or avp) ip to put in Contact and Via when topoh is enabled. i see that the 'mask_ip' parameter of topoh module is a string. so we can not set a dynamic value here unfortunately. Thanks

kamcmd autocompletion

by Antoine DEBARRE

Hi, I just installed kamailio v5.5 via deb.kamailio.org packages (debian 11). Seems that kamcmd autocompletion doesn't work at all. It is OK for v5.4 via official debian packages (packages.debian.org/bullseye/kamailio) Best regards, -- <https://app.livestorm.co/comdata-group/metaverse-what-will-cx-look-like-in-…>

Recommended openSSL version

by Igor Olhovskiy

Hello! Due to I still experience irregular Kamailio 5.4 crashes (like 1/month) related to SSL (using websockets and SIPS) I'm wondering, could openSSL upgrade change the situation? As of now in CentOS 7 I have 1.0.2k version. Does anyone have experience to fix crash-related to TLS problems with openSSL upgrade? Or maye some tuneup of TCP parameters can help here?My current setup is quite simple: children=4 enable_tls=yes tcp_accept_no_cl=yes tcp_connection_lifetime=600 tcp_max_connections=998976 # 1000000 - 1024, so we're leaving 1k for system reserve tls_max_connections=998976 Number of clients ~ 200 constantly connected to websocket. -- Best regards, Igor

Siremis JSONRPC problem on Bullseye

by Joseph Goettgens

I am not sure what I have to look for and I didn't change the initial config files (except for the 666 mode for kamailio_rpc.sock). As far as Kamailio is concerned the socket files files do exist: root@deb11srv1-kamailio:/var/www/siremis-5.3.x# ls -l /run/kamailio/ insgesamt 4 srw------- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_ctl -rw-r--r-- 1 kamailio kamailio 5 7. Jun 11:37 kamailio.pid prw-rw---- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_rpc.fifo srw-rw-rw- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_rpc.sock When I look at siremis/log/ERR.log I repeatedly get: '06/07/2022','09:43:29','ERR','ErrorHandler','socket_bind(): unable to bind address [2]: No such file or directory','' This disappears when I put the local file socket in /tmp: <UnixSockLocal name="unixsocklocal" address="/tmp/siremis_rpc.sock" timeout="3.0"/> which was probably done this way in previous versions of Siremis (before systemd private tmp config). In this case I get no error messages, but still no answers (as expected). The next step seems to get UnixSockLocal right.

slow timer too slow: overflow

by Denys Pozniak

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

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

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

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
