Re: [SR-Users] play_media sounds interrupted

I was thinking about timers, but rtimer cannot be triggered in an event route. I used a "timer" module, it could trigger another route from the event route but when a new route is triggered unblock_media() is not aware of the call-id and if i assign call-id to a variable in the event route, that variable is unavailable at new route. Hope that make sense. here is my peace of code: loadmodule "timer.so" modparam("timer", "declare_timer", "PB_TIMER=START,5000"); route[START]{ xlog("current call id at event route is $ci, but call-id avp is $avp(call_id)"); unblock_media("all"); timer_enable("PB_TIMER",0); #we need to disable timer or it will be triggered over and over again } event_route[dialog:start]{ xlog("L_INFO", "dialog started, received 200OK"); #block_media(); play_media("all file=/usr/local/src/myfile.wav"); $avp(call_id)=$ci; timer_enable("PB_TIMER",1); }

play_media sounds interrupted
by Stepan Kislyakov 11 Oct '22

11 Oct '22

Hi, I'm using latest kamailio 5.6.2 and rtpengine. I need to play announcement to both parties when call is answered by callee. Now I run play_media in event route but when audio start announcement sounds like we have a 50% packet loss. After it is completed there is no problem with audio both sides. I figured out that if i do block_media() my announcement play perfectly but i dont understand how to do unblock_audio() after announcement ends. Appriciate any help! here is my code: event_route[dialog:start]{ xlog("L_INFO", "dialog started, received 200OK"); block_media(); play_media("all file=/usr/local/src/myfile.mp3"); #unblock_media(); } -- Best Regards Stepan Kislovich

IPSec problem with P-CSCF
by Ali Akbar Hemmati 11 Oct '22

11 Oct '22

Hi everyone, I am using Kamailio as an IMS server. The UE first sends its SIP REGISTER over TCP and gets a 401 in response. Then the UE starts sending its packets over ESP. These ESP packets reach P-CSCF but are not delivered to its process by the kernel. We can see ESP packets in P-CSCF using wireshark. The ports used are correct (both client and server) based on their prior negotiations. We have also checked xfrm policies using the command `ip xfrm policy list` and seems right regarding prior negotiations. Our Linux kernel version is 5.4 and the OS is Ubuntu 20.04. Has anyone any clue of the root cause of this problem? Any ideas are appreciated. Thanks, Aliakbar

kamcli folder
by Volker Denneberg 11 Oct '22

11 Oct '22

hello, I'm not very familiar with PHP, so this may be a stupid question. I'm following https://github.com/kamailio/kamcli to install kamcli. Now i am at $ pip3 install -r requirements/requirements.txt which i should "run inside kamcli folder". So far, I don't have a kamcli folder, so i assume i have to create it. Any recommendations where ? Thanks in advance, Volker

detect tcp connection close using tcpops module
by sthustfo 11 Oct '22

11 Oct '22

I am running latest kamailio 5.6.2 and attempting to detect tcp/tls connection being disconnected or closed using tcpops module. As suggested in tcpops documentation at https://www.kamailio.org/docs/modules/devel/modules/tcpops.html, registered event routes as below. event_route[tcp:closed] { xlog("L_INFO", "$proto connection closed ($conid)\n"); } event_route[tcp:timeout] { xlog("L_INFO", "$proto connection timed out ($conid)\n"); } event_route[tcp:reset] { xlog("L_INFO", "$proto connection reset by peer ($conid)\n"); } Now it is observed that the event route is being called but the $conid is not set. The logs show the below log statements and extra data is (nil). 24(4263) DEBUG: <core> [core/tcp_read.c:284]: tcp_read_data(): EOF on connection 0x7ffff2ff8b90 (state: 0, flags: 4018) - FD 7, bytes 0, rd-flags 10000 ([10.8.137.33]:51069 -> [10.8.137.33]:5060)24(4263) DEBUG: <core> [core/tcp_read.c:1500]: tcp_read_req(): EOF 24(4263) DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0x555555ab6960, 7, -1, 0x10) fd_no=2 called 24(4263) DEBUG: <core> [core/tcp_read.c:1870]: handle_io(): removing from list 0x7ffff2ff8b90 id 1 fd 7, state 2, flags 4018, main fd 51, refcnt 2 ([10.8.137.33]:51069 -> [10.8.137.33]:5060) 24(4263) DEBUG: <core> [core/tcp_read.c:1653]: release_tcpconn(): releasing con 0x7ffff2ff8b90, state -1, fd=7, id=1 ([10.8.137.33]:51069 -> [10.8.137.33]:5060) 24(4263) DEBUG: <core> [core/tcp_read.c:1657]: release_tcpconn(): extra_data (nil) 32(4271) DEBUG: <core> [core/tcp_main.c:3651]: handle_tcp_child(): reader response= 7ffff2ff8b90, -1 from 0 32(4271) DEBUG: <core> [core/tcp_main.c:3576]: tcp_emit_closed_event(): TCP closed event creation triggered (reason: 0) 32(4271) DEBUG: tcpops [tcpops.c:295]: tcpops_handle_tcp_closed(): received TCP closed event 32(4271) DEBUG: tcpops [tcpops.c:249]: tcpops_tcp_closed_run_route(): event reason id: 0 rt: 1 32(4271) DEBUG: <core> [core/parser/parse_fline.c:249]: parse_first_line(): first line type 1 (request) flags 1 32(4271) DEBUG: <core> [core/parser/msg_parser.c:679]: parse_msg(): SIP Request: 32(4271) DEBUG: <core> [core/parser/msg_parser.c:681]: parse_msg(): method: <OPTIONS> 32(4271) DEBUG: <core> [core/parser/msg_parser.c:683]: parse_msg(): uri: <sip:you@kamailio.org> 32(4271) DEBUG: <core> [core/parser/msg_parser.c:685]: parse_msg(): version: <SIP/2.0> 32(4271) DEBUG: <core> [core/parser/parse_hname2.c:301]: parse_sip_header_name(): parsed header name [Via] type 1 32(4271) DEBUG: <core> [core/parser/parse_via.c:2639]: parse_via(): end of header reached, state=2 32(4271) DEBUG: <core> [core/parser/msg_parser.c:555]: parse_headers(): Via found, flags=2 32(4271) DEBUG: <core> [core/parser/msg_parser.c:557]: parse_headers(): this is the first via 32(4271) exec: *** cfgtrace:dbg_cfg_trace(): unknown_route=[tcp:closed] c=[/usr/local/etc/kamailio/kamailio.cfg] l=976 a=26 n=xlog32(4271) INFO: <script> tcp connection closed (<null>) Can anyone provide any pointers on what I am missing?

suppress t1 timer retransmissions?
by Brooks Bridges 10 Oct '22

10 Oct '22

So I have a very odd situation that requires me to suppress retransmissions when using t_reply() to send a response back to a UAC that is horribly broken but I'm stuck with for the time being. In the previous iteration of this platform it was fine since I was using a stateless reply, so even though it wasn't "right" it still worked out. I need to replicate this behavior in the event route for http_async_client(), which prevents me from being able to use t_release(). Anyone have any clever ideas? Brooks Bridges 1200 S.

cannot register ACC CDR JSON engine when using acc_json module
by Alexis Prodhomme 10 Oct '22

10 Oct '22

Hi everyone, I have some troubles using acc_json module. I can't load it and I don't understand why it fails. The configuration is quite basic: Debian 10 and Kamailio (fails in 5.5 and 5.6) installed using APT repository. Here is parts of my config: loadmodule "kex.so" loadmodule "corex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "dialog.so" loadmodule "acc.so" loadmodule "acc_json.so" modparam("acc_json", "cdr_enable", 1) I also tried with those 4 additionnal settings with no success: modparam("acc_json", "cdr_output_syslog", 1) modparam("acc_json", "cdr_log_facility", "LOG_LOCAL3") modparam("acc_json", "cdr_enable", 1) modparam("acc_json", "cdr_expired_dlg_enable", 1) As soon as I set cdr_enable to 1, it displays the "*cannot register ACC CDR JSON engine*". Here is logs: 0(2488) DEBUG: <core> [core/sr_module.c:969]: init_mod(): acc_json 0(2488) DEBUG: <core> [core/sr_module.c:722]: find_mod_export_record(): found export of <bind_acc> in module acc [/usr/lib/x86_64-linux-gnu/kamailio/modules/acc.so] 0(2488) INFO: acc_json [acc_json_mod.c:159]: mod_init(): janson version : 2.12 0(2488) DEBUG: <core> [core/mem/q_malloc.c:374]: qm_malloc(): qm_malloc(0x7f0a6b154010, 56) called from acc: acc_mod.c: acc_register_engine(725) 0(2488) DEBUG: <core> [core/mem/q_malloc.c:419]: qm_malloc(): qm_malloc(0x7f0a6b154010, 56) returns address 0x7f0a6b220b40 frag. 0x7f0a6b220b08 (size=56) on 1 -th hit 0(2488) DEBUG: acc_json [acc_json_mod.c:269]: acc_json_init(): init ... 0(2488) DEBUG: acc [acc_mod.c:741]: acc_register_engine(): new acc engine registered: json 0(2488) DEBUG: <core> [core/sr_module.c:722]: find_mod_export_record(): found export of <load_dlg> in module dialog [/usr/lib/x86_64-linux-gnu/kamailio/modules/dialog.so] 0(2488) ERROR: acc_json [acc_json_mod.c:245]: mod_init(): cannot register ACC CDR JSON engine 0(2488) ERROR: <core> [core/sr_module.c:974]: init_mod(): Error while initializing module acc_json (/usr/lib/x86_64-linux-gnu/kamailio/modules/acc_json.so) ERROR: error while initializing modules May it be related to the Jansson version ? I use the native one from Debian 10, v2.12. Do you have any advice, or some tips to debug my issue ? I don't really want to use acc module and parse CDRs manually from syslog, json is far easiest for this job. Thank you -- Alexis R&D Sewan
