Uneven-distribution of calls
by satyaprakash ch 14 Nov '22

14 Nov '22

Hi, what would be the reason for the *Un-even* distribution of calls from kamailio proxy to freeswitches. The dispatcher lists are having the same weight. For example: If we are having 4 freeswitches, the calls are evenly distributing for 3 freeswitches but there is high calls for the 4th freeswitch. The dispatcher weight for the freeswitches are: rweight=50;weight=50;cc=1; Thanks and regards, Satya

kamcmd dlg.list => ERROR: reply too big
by Benoît Panizzon 14 Nov '22

14 Nov '22

Hi List I fear I am loosing dialogues somehow. We have implemented counting concurrent connections from customers by using set_dlg_profile. Sometimes, the concurrent channel count does not decrease, despite the dialog end being detected. Now I suppose I have maybe a dozen concurrent calls running, but kamcmd dlg.list is unable to dump the list. kamcmd dlg.dump_file generates quite a large file. I was running into SHM issues while load-testing and had to increase SHM to 1024 to accommodate all dialogues and vars. I fear this could have caused corrupted dialogues? Dialog Data is replicated via DMQ between two instances which I too care never to restart at the same time. Will completely stop and then restart the two affected instances and clear the dialog and dialog_vars tables to see if this issue is manifesting itself again. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

External script
by Володимир Іванець 11 Nov '22

11 Nov '22

Hello! I was wondering how everyone uses exec_cmd(). I'm using it to call an external script directly from a worker route which locks it for the time of execution. If all that is needed is to call it and forget, should the best option be to call the async route with exec_cmd()? Thanks a lot for any input on this topic!

Kill child process created by app_python module
by Marat Gareev 11 Nov '22

11 Nov '22

Hello! I'm trying to use app_python module to perform periodic actions. This is a simple python code def _update(): while True: _action() time.sleep(60) class noop_handler: def child_init(self, rank): return 0 def ksr_request_route(self, msg): return 1 def mod_init(): # signal.signal(signal.SIGTERM, signal.default_int_handler) proc = multiprocessing.Process(target=_update) # proc.daemon = True proc.start() ksr.notice('Forked process {} to update\n'.format(proc.pid)) return noop_handler() After killing kamailio processes with SIGTERM signal (killall kamailio) I see zombie process. And if I try to process the signal in daemon mode (see the comments in the snippet above), I get critical errors in the logs and still see processes: 0(37001) NOTICE: <core> [core/kemi.c:124]: sr_kemi_core_notice(): Forked process 37002 to update 1(37003) ERROR: <core> [core/udp_server.c:464]: udp_rcv_loop(): recvfrom:[4] Interrupted system call Process Process-1: Traceback (most recent call last): File "/usr/lib64/python2.7/multiprocessing/process.py", line 258, in _bootstrap self.run() File "/usr/lib64/python2.7/multiprocessing/process.py", line 114, in run self._target(*self._args, **self._kwargs) File "/tmp/script.py", line 155, in _update time.sleep(period) KeyboardInterrupt 0(37001) ALERT: <core> [main.c:774]: handle_sigs(): child process 37002 exited normally, status=1 0(37001) INFO: <core> [main.c:802]: handle_sigs(): terminating due to SIGCHLD 1(37003) ERROR: <core> [core/udp_server.c:464]: udp_rcv_loop(): recvfrom:[4] Interrupted system call 8(37014) CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 4 1(37003) ERROR: <core> [core/udp_server.c:464]: udp_rcv_loop(): recvfrom:[4] Interrupted system call So, how I can kill child process by SIGTERM signal?

acc module => account register messages?
by Benoît Panizzon 11 Nov '22

Hi Is there a way to get register messages into accounting? This could come in handy while helping figure out if clients were not registered while calls attemted to reach them. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

evapi:message-received and state
by Alex Balashov 07 Nov '22

07 Nov '22

Hi, I am t_continue()ing a transaction inside of event_route[evapi:message-received]. The $evapi(msg) has quite a bit of payload that will be needed by the resumed transaction. Is there a good way to inject this data into the transaction scope externally? No [X]AVPs created in the event_route persist, of course, since the route is scoped outside of the transaction. I have been using htable to pass data into the transaction, keyed by the index and label. But, this strikes me as a kind of clumsy memory synchronisation anti-pattern. Is there a better way?

Kamailio Not Responding to Connections
by Carlos Escalona 07 Nov '22

07 Nov '22

Hello! I hope all of you are having a nice day. I would like some help. I recently had some troublesome events in my Kamailio setup, at a particular time of the day specifically after lunch when my platform's traffic spikes Kamailio suddenly stops responding to any connection and restarting it didn't fix the problem basically I have to restart the hardware to get out of that failed state. The only unusual log is the following: Oct 28 16:49:10 ip-172-32-16-97 /usr/sbin/kamailio[952]: ERROR: topos [tps_storage.c:615]: tps_storage_record(): failed to store Someone recently posted a problem that occurred when doing stress tests with the siptrace module active and the service that collects the traces was failing, I wonder if this may be the case because it is possible that something similar is happening in my case. Unfortunately, I don't have much more information since I had to implement a quick fix that mitigates the problem for now, but I would like to be able to go back to the previous configuration that seemed more appropriate. My plan is to test now that I have solved the problem I had with the traces service, but I wanted to know if anyone had experienced a similar situation.

Serial Forking on BYE message
by Ilie Soltanici 05 Nov '22

05 Nov '22

Hello, I have a challenge here to do serial forking, not when the call is failed on the first destination, but when the call is ended. So, the first will go to one destination, will be answered, and when it's ended the BYE message should be dropped and forward the initial INVITE to another location. Is that possible?
