Hi everybody, I'm just testing Kamailio 5.4.1 with dialog replication over DMQ. This seems to work very good. Dialogs are replicated without problems. When I'm restarting one node I would have expected, that all dialogs are synced again, just like in dmq_usrloc. But this does not happen. After a restart the nodes dialog-list is empty. Did I miss somethin? Is there a special parameter that I have to set?

Is Min-SE check broken?

by harneet singh

Hi All, I am facing an issue in understanding how the min_se should be working in kamailio. As per the SST documentation, it seems like if the min_se is configured as 500, then any value of Session-Expires OR MIN-SE if lower than 500, can be responded to by a 422. However, I strangely see the reverse happening. To investigate further, I looked in to the ki_sst_check_min() code in the master, and these seems like a potential issue. Ref Code: Inside ki_sst_check_min(), there is an if condition like below: if (sst_min_se < MIN(minse, se.interval)) { However, shouldn't it be the other way around? ie if (sst_min_se > MIN(minse, se.interval)) { because we need to send 422 if the received value(in INVITE etc) is smaller than the sst configure min_se value? I also found a different documentation, at https://git.sgu.ru/oldssu/ex-opensips/blob/cb9df8d59dbb254a9d862569fd5d11f6… where the check is as below? if (sst_min_se > MIN(minse, se.interval)) { Can someone confirm if this is broken, or my understanding is incorrect?

Config works fine with mysql as topos backend. So the bug is restricted to topos-redis.

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-…>

Create new listener on the fly

by H Yavari

Hi Kamailio community, I am running an IPsec server beside Kamailio, so I am interested to know if there is any method to create a SIP listener on a specific port on the fly. I mean, when I create the IPsec SAs through the IPsec server, I ask Kamailio to create a listener/handler for that port too.This case might be very rare, but it is always good to hear community ideas. Thank you. Regards,Hossein

Kill child process created by app_python module

by Marat Gareev

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?

Pipelimit needs restart to reload values

by Duarte Rocha

Greetings, I've been using the pipelimit module and the pl_check function to control users rates in my proxy. if (!pl_check("$var(UserID)", "TAILDROP", "$var(UserRate)")) { pl_drop(); exit; } In this case $var(UserID) is the pipe and $var(UserRate) is the maximum rate. The value of the rate is retrieved on every call via query to a DB. If I change the UserRate value to 0 CPS on the DB calls are not rejected unless they go over 1 CPS. However, if I restart Kamailio all calls are correctly rejected. Why does this happen? Can I change this behaviour? Cheers, Duarte

Appending new branches via external means

by Alex Balashov

Hi, Is there a means of appending new branches from config script for a transaction which is already proceeding in the background, without using `tsilo`? That is to say, I have an async transaction which is resumed in an async worker and is t_relay()’d away to some destination. Meanwhile, I have learned about new destinations for it to try via an incoming registration, and would like to append additional parallel forking branches to that transaction, even though it is already proceeding. ts_append() does this for me; the issue I have is that it is mediated through a registrar, but I am not a registrar. My registrar is upstream, and my proxy is just a front-end to it. So, in essence, I require something like `tsilo` at a more general level, where contacts can be populated by some other mechanism rather than being learned via callbacks out of `usrloc`. Is there a way to accomplish this?
