Hello,
the interface selection is based on the conditions met at a specific
moment, depending also on the operations done in the code case by case.
If you want to enforce a specific one, then you have to specify it via
modparam.
Cheers,
Daniel

Hello,
I captured a tcpdump on this scenario and saw that in fact, the
siptrace is sending the 403 Forbidden towards Homer.
The issue is that for this local reply, Kamailio instead of using the
private interface as it does for the other messages, is choosing the
public interface, so the local reply doesn't arrive on heplify side.
After forcing the socket with send_sock_addr, the reply appears on Homer.
modparam("siptrace", "send_sock_addr", "sip:x.x.x.x:xxxx")
From the documentation, I saw that if we don't use the send_sock_addr
Kamailio will choose the interface, but shouldn't it choose always the
same interface?
Thanks for the help finding the issue.
Regards,
Tiago

Hello,
logs indicate that the siptrace is engaged when the reply is sent out:

Can you watch the network traffic with ngrep/wireshark and check
if the reply is actually sent over?
Cheers,

Hello,
So I tested with the following configuration:
modparam("siptrace", "duplicate_uri",
"sip:x.x.x.x:9060")
modparam("siptrace", "hep_mode_on", 1)
modparam("siptrace", "trace_to_database", 0)
#modparam("siptrace", "trace_flag", FLT_SIPTRACE)
modparam("siptrace", "trace_on", 1)
modparam("siptrace", "trace_mode", 1)
modparam("siptrace", "hep_version", 3)
modparam("siptrace", "hep_capture_id", 2040)
I can see this on the logs:

Hello,
local replies should be captured with trace_mode=1. Run with
debug=3 in kamailio.cfg and attach all log/debug messages
printed by Kamailio for such case (from the INVITE to the ACK
processing).
Cheers,
Daniel

Hi,
Thanks for your reply.
We had the modparam("siptrace", "trace_mode", 1) but the
issue with that is that local error answers from kamailio
doesn't appear.
For example, when Kamailio receives the INVITE and replies
with a forbidden, the Invite and the ACK is there but the
Forbidden is not.
So with "trace_mode" 1 , everything works fine except this
messages missing and this was the problem that we tried to
solve messing around with the functions and flags.
Regards,
Tiago

Hi,
Any one have some idea about this? Or how it should be
configured in
order to still have the original response
received in kamailio instead of the mapping one?
If you want all the traffic mirrored, then look at:
*
https://www.kamailio.org/docs/modules/stable/modules/siptrace.html#siptrace…
<https://www.kamailio.org/docs/modules/stable/modules/siptrace.html#siptrace.p.trace_mode>
It is simpler that the use of functions and flags to
select what
messages should be mirrored.
Cheers,
Daniel
