Hi Federico,
Thanks, but no trace_flag defined. I quoted all sip_trace module parameter from my cfg. I want to trace in SIP mode, not in HEP mode, this might be relevant.
Cheers,
Henning

Hi Henning,
do you still have the trace_flag defined? If yes comment it, because in 5.3.x it clashed with sip_trace_mode().
Cheers,
Federico

Hello,
this seems not generally true. Just testing it with Kamailio 5.3.4.
modparam("siptrace", "trace_to_database", 0)
modparam("siptrace", "trace_on", 1)
modparam("siptrace", "duplicate_uri", "sip:XXXX:YYYY")
route{ … sip_trace_mode("t");… }
This is ignored, no messages are traced. If I add a sip_trace(“XXXX:YYYY”) as well, it trace one message (not two).
It seems that the sip_trace_mode(“t”) is just ignored. If I remove the URI from the sip_trace, it also does not trace anything, it seems to also ignore the duplicate_uri. No error messages etc.. in the logs.
Cheers,
Henning

Hi Karsten,
you don't have to call sip_trace() if you call sep_trace_mode("t") otherwise you'll have duplicated messages.
Cheers,
Federico

Hi Sergiu,
thanks for pointing that out. I tried kamailio 5.3.4 with the settings below.
Works now. I see the answers of kamailio itself.
Unfortunately my UAC input messages are now doubled in homer.
Will check that tomorrow.
And for fun - with sip_trace i can send to more than one target, nice.
#!ifdef WITH_HOMER
# start duplicate the SIP message here
sip_trace();
# address - The address in form of SIP URI where to send a duplicate of traced message.
sip_trace("sip:127.0.0.1:9060<http://127.0.0.1:9060>");
sip_trace_mode("t");
#setflag(22);
#!endif
modparam("siptrace", "force_send_sock", "MY_LOCAL_SENDSOCK")
modparam("siptrace", "duplicate_uri", "MY_HOMER_CAPTURE")
modparam("siptrace", "hep_mode_on", 1)
modparam("siptrace", "hep_version", 3)
modparam("siptrace", "trace_to_database", 0)
##modparam("siptrace", "trace_flag", 22)
modparam("siptrace", "trace_on", 1)
modparam("siptrace", "trace_mode", 3)
modparam("siptrace", "hep_capture_id", MY_HEP_NODE_ID)

Compared to previous versions, under 5.3, one must invoke the sip_trace_mode() function if you wanted to see the full SIP flow in Homer. It's not clear from documentation that it's a must function, but it did fix the problem in my case.
For example:
sip_trace();
sip_trace_mode("t")

Hi Frederico,
good point. Will also update my test setup and have a look at the new functions.

Hi,
did you try to capture the traffic going towards homer?
Siptrace module has internally changed in release 5.3 and some things that used to work in 5.2 are not working or are not doing it in the expected way.
There have been several fixes since 5.3.0, some of them are still only in master branch, I suggest you to use the latest 5.3.4 and have a look at the new capture modes and http://www.kamailio.org/docs/modules/5.3.x/modules/siptrace.html#siptrace.f.sip_trace_mode function.
Hope this helps.
Cheers,
Federico

Hi list,
I saw some strange behavior in Kamailio 5.3.0 with HEPv3. My Kamailio serves webrtc and sip tls and captures that to an Homer 7.7 instance.
I see only the UAC Parts of the message and not the answers from Kamailio in that scenario.
Maybe I reached the max Paket size for udp. Hard to debug. In production I saw everything (but there I used and older Kamailio 5.2.x and Homer 5.5 which can handle fragment udp).
Any ideas how to hunt the root cause of the problem?
Cheers
Karsten
