Hello,
Kamailio SIP Server project is organizing another meeting of its
developers and community members during November 7-8, 2023, hosted again
by sipgate.de in Dusseldorf, Germany.
The event is intended to facilitate the interaction between Kamailio
developers and contributors in order to offer a convenient environment
for working together on several topics of high interest for the project,
including writing code for Kamailio and its tools, improving
documentation, or discuss about future development.
Everyone from the community is welcome to join, developer or user
interested in helping the project. Please note we have a limited
capacity of seats in the meeting room, the main policy for accepting
participants being first come first server. Also, very important to be
aware that this is not an event to learn how to use Kamailio.
More details about the event, the venue, how to register, are available at:
* https://www.kamailio.org/w/developers-meeting/
Looking forward to those two intensive hacking Kamailio days in Dusseldorf!
Cheers,
Daniel

Dear friends, I have a question: When adding a custom module in kamailio, I referenced a third-party library. There was no problem with compilation, but when I ran it, it reported that the third-party library could not be found. What is the reason?
The current Makefile is as follows：
```
# WARNING: do not run this directly, it should be run by the main Makefile
include ../../Makefile.defs
auto_gen=
NAME=rocketmq.so
THIRDPARTY=/mnt/vdd/kqbi2/3rdparty
ROCKETMQ_ROOT_PATH=${THIRDPARTY}/rocketmq
CXX?=g++
LD?=g++
LIBS+=-L$(LOCALBASE)/lib -L$(ROCKETMQ_ROOT_PATH)/lib/linux/x64 crocketmq.o -lstdc++ -lrocketmq
DEFS+=-I$(LOCALBASE)/include -I${ROCKETMQ_ROOT_PATH}/include
CXXFLAGS=$(CFLAGS:-Wno-deprecated option=)
CXXFLAGS+=-Wno-write-strings -Wno-deprecated -Wno-unused-function -Wno-sign-compare -Wno-strict-aliasing
include ../../Makefile.modules
crocketmq.o: crocketmq.cpp crocketmq.h
@echo "Compiling $<"
$(CXX) -std=c++11 $(CXXFLAGS) $(CFLAGS) $(C_DEFS) $(DEFS) -c $< -o $@
rocketmq.so: crocketmq.o
modclean:
-@rm -f crocketmq.o crocketmq.d rocketmq_mod.o rocketmq_mod.d
clean clean-modules: modclean
proper realclean distclean maintainer-clean: modclean
```
There is no problem in compiling, but when running, the third-party librocketmq.so library cannot be found, and various export LD_LIBRARY_LIBRARY also does not work.
```

Hi
I have a scenario where I need to implement serial forking but each
destination has also a next hop proxy. I can do the forking using
append_branch, but how can I set the destination URI for each branch? In
some cases the R-URI does not change, only the next hop proxy.
Example:
R-URI Next Hop
user1(a)domain.com XXX.XXX.XXX.XXX
user1(a)domain.com YYY.YYY.YYY.YYY
user2(a)domain.com XXX.XXX.XXX.XXX
I was thinking I could use a htable to store the next hop using the
R-URI as the key, but as can be seen above there are possibly duplicate
R-URIs with only the next hop changing.
Thanks.

Morning
What have you got your listen / advertise address / port set as?
See this link > https://www.kamailio.org/wiki/cookbooks/5.5.x/core#advertised_address
I'd probably start by looking at that.

Hello,
I'm using Kamailio as SIP proxy to receive INVITE packets, randomize A-number and then relay it to a certain gateway.
I noticed that a Via header is added to the INVITE sent by Kamailio to the gateway with 0.0.0.0 as address as shown below:
Via: SIP/2.0/UDP 0.0.0.0;branch=z9hG4bK2d97.61de75dd58fa7ca7450cc8b9b01db62f.0
As far as I know, the IP that should be used in the new added VIA header must be Kamailio IP, but it's not the case here, knowing that Kamailio is not behind NAT.

Hello,
Is there a way to change the transaction order when a failure fork occurs -- to explain, endpoint 1 calls endpoint 2. Call towards endpoint 2 goes unanswered, and so the call forks to voicemail, I see that an INVITE is sent towards my voicemail server first, followed by a CANCEL towards the endpoint; can I send the CANCEL first to the endpoint and then INVITE towards my voicemail server. I'm essentially using the bundled/sample configurations for testing.
Thank you.
UA1(192.168.0.1) --> kamailio (internal:192.168.0.2 public:1.1.1.1) --> UA2(2.2.2.2)
if in UA1 INVITE, I write KSR.rr.record_route().
so UA2(2.2.2.2) received sip msg (Record-Route: <sip:1.1.1.1:7080>), so Kamailio can received BYE/ACK from UA2.
but，Kamailio can't received BYE/ACK from UA1.
if in UA1 INVITE, i write KSR.rr.record_route_advertised_address("192.168.0.2"), then Kamailio can received BYE/ACK from UA1, but not from UA2.
what can i do, let Kamailio receive BYE/ACK from both sides ？
Hello all,
Can you please clarify part of the following doc for me?
--
6.7. early_timeout (integer)
The timeout (in seconds) after which the dialogs in unconfirmed or early
state (no final response received) are destroyed.
* Default value is “300 (5 minutes)”. *
*Example 1.7. Set early_timeout parameter*
...
modparam("dialog", "early_timeout", 180)
---
In the case where Kamailio acts as an SBC, will kamailio send a SIP BYE
message to both devices (UAC and UAC)?
Or
Can Kamailio send a BYE message to both parties when timer b has expired?
If yes, how to do it?
Regards
Abdoul
UA(192.168.0.11) received 183, find Record-Route(36.140.122.12)
then send ACK to 36.140.122.12(Kamialio public ip) not 192.168.0.2(kamailio internal ip), so Kamailio can't receive ACK.
this is my config，192.168.0.11 -> Kamailio -> Other SBC(public ip)
function ksr_request_route()
if KSR.is_INVITE() then
KSR.rr.record_route();
KSR.nathelper.fix_nated_contact()
end
end
This question has been bothering me for a long time, help me

Hi All,
I use kamailio In front of Asterisk and kamailio needs to refresh registrations periodically towards Asterisk to ensure the availability of users from Asterisk side.
I use uac module and call uac_req_send() for sending REGISTER requests.
I set $uac_req(evroute)=1
The event_route[uac:reply] is called fine, but in kamailio logs I see the next lines:
CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f114995ada8), called from uac: uac_send.c: uac_send_tm_callback(860), first free uac: uac_send.c: uac_resend_tm_callback(732) - ignoring
After some time, kamailio has crashed.
CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f114995ada8), called from uac: uac_send.c: uac_send_tm_callback(860), first free uac: uac_send.c: uac_resend_tm_callback(732) – ignoring
CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 34
ALERT: <core> [main.c:774]: handle_sigs(): child process 1407950 exited by a signal 6
Any idea that is it a bug or I use something wrong in config?
Thanks in advance!
