I have kamailio behind a TLS termination proxy so the sockets are correctly
deduced to be TCP. However the clients only talk TLS to the proxy and are
confused when the top Via header added by Kamailio is TCP. Is there a way
for Kamailio to forcibly pretend its protocol is TLS? Like
advertised_address but "advertised_protocol" instead.
(With pjsip testing: it has a flag use_tls which ignores TCP from Kamailio
and continues to use the persistent TLS transport to proxy. Linphone fails
because it tries to honor TCP in Via and is unable to establish TCP
transport).
BTW I am using t_relay_to_tcp so Kamailio will return traffic to the proxy
as TCP even though the contact addresses specify transport=TLS.
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?
BR, Björn

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?
Regards,
Harneet

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

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

So, how I can kill child process by SIGTERM signal?
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
