Hello!
Is it possible to find out the name of the onreply_route that was set
before?
Something like this:
t_on_reply("MANAGE_REPLY");
...
if ( t_is_set("onreply_route") ) {
get_onreply_route_name();
...
}

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,
I have still the problem that my htables are not written into a sqlite
db when I shutdown kamailio.
Manual writing via:
kamcmd htable.store ...
is working.
As I can see in the logs with highest loglevel, the function destroy()
is never called.
ht_db_url.len is > 0
ht_db_init_con() should work, else nothing would work with the db.
But I can not see the debug messages from ht_db_open_con()
Any ideas?
Best regards,
Bernd
Hello,
I am looking information about Kamailio operating as an SBC.
I saw this video of Kamailio World 2021: Kamailio As An SBC For Network Segregation:
https://www.youtube.com/watch?v=UW6l3R4OnsY&t=1381s
But where I can find more detailed technical information ?

Hello,
In reference to this issue https://github.com/kamailio/kamailio/issues/3081 I've been advised to set http_reply_parse to "no" which I did (and it is the default value anyways).
# grep http_reply_parse /etc/kamailio/kamailio.cfg
http_reply_parse=no
After setting this, I still get these parsing errors:
{ "idx": 23, "pid": 102, "level": "ERROR", "module": "core", "file": "core/parser/msg_parser.c", "line": 748, "function": "parse_msg", "logprefix": "", "message": "ERROR: parse_msg: message=<HTTP/1.1 100 Continue\r\n\r\nHTTP/1.1 200 OK\r\ndate: Wed, 26 Jul 2023 16:43:19 GMT\r\ncontent-length: 224\r\ncontent-type: text/plain; charset=utf-8\r\n\r\n{\"result\": {\"ruri\":\"\",\"fU\":\"\",\"tU\":\"\",\"privacy\":\"\",\"identity\":\"\",\"error\":{\"code\":0,\"message\":\"\"},\"mb\":\"\",\"Headers\":null,\"encrypted\":\"\",\"sipsScheme\":\"\",\"attestation\":\"\",\"authUser\":\"\",\"authPassword\":\"\",\"disableStirShaken\":\"\"}}>" }
Is there anything that I am missing beyond setting that parameter?
Thank you,

Hello!
We had several crashs of Kamailio (5.3.4) in the last weeks. Each time, the
last logs are:
/usr/local/sbin/kamailio[20942]: CRITICAL: <core> [core/forward.c:347]:

Hi,
I am building a configuration script where for some traffic flows
parallel forking will be needed, and in this case I need to go beyond
the default max limit of the max amount of branches.
Apart from this specific case the traffic load that kamailio will need
to handle is very low, let's say just one second here and there with up
to 5 concurrent calls at most.
This limit is as far as I understand set here:
usr/local/src/kamailio-5.6/kamailio/src/core/config.h
And the default limit is:
#define MAX_BRANCHES_LIMIT 32 /*!< limit of maximum
number of branches per transaction */
Here are the questions I have related to this:
1) If I increase the value of this constant in config.h, how high is it
reasonable to set this value and still have a stable system?
2) If I increase MAX_BRANCHES_LIMIT beyond 32, are there also other
parameters that needs to be changed for the system to be able to cope,
and if so whichparameters?
Regards,
Lars
Bastian,
According to mine stats all seems ok...
# kamctl stats shmem
{
"jsonrpc": "2.0",
"result": [
"shmem:fragments = 330",
"shmem:free_size = 1889418024",
"shmem:max_used_size = 258962624",
"shmem:real_used_size = 258065624",
"shmem:total_size = 2147483648",
"shmem:used_size = 248809096"
],
"id": 212042
}
pkg.stats also not showing any signs of exhausting.
For me what is working is server can send packets, but not receive em
back even. And it's happening only on 1 interface.

Hi people,
I installed Kamailio 5.3 on Ubuntu Server 22 LTS, but I am not able to resolve several PHP errors that occur when I try to open the website http://localhost/siremis/.
Which Linux distro and version is best suited for installation?
Is Kamailio version 5.3 operational or is it better to use version 4.4?
