Re: [SR-Users] siptrace & topos modules on 5.3

Hello,

ahh, just noticed you are tracing from the config at transaction layer, meaning that traffic is sent during config processing when the content is without topos changes.

To get the traffic as seen on the network, set modparam trace_mode=1 and remove the use of sip_trace()/sip_trace_mode() in routing blocks. You can still filter what is sent out using event_route blocks, if you do not want all the traffic to be mirrored.

Cheers, Daniel

Hi Daniel,

I did this change but unfortunately no change. Anything more I could check?

Hi,

We are using kamailio 5.3 latest version with the topos module.
We have added Homer 7 latest version to consolidate traces from
all kamailios and we have enabled siptrace module on kamailio to
send data to homer. What we have seen up today is that traces on
homer have sip headers before topos changes. So if I look at
the same call on sngrep on the kamailio machine, I see the
correct topos changed headers. If I check the same call on Homer
I see headers without topos changes. Also we get duplicate
headers on ACKs on homer.

I was wondering what we have done wrong in the config and we have
these results on homer. Any help will be much appreciated!

Our config has:
===========-
#!substdef "!MY_HOMER_CAPTURE!sip:MY_HOMER_IP_ADDR:MY_HOMER_PORT!g"
#!substdef
"!MY_LOCAL_SENDSOCK!sip:MY_KAMAILIO_IP:MY_LOCAL_SEND_PORT!g"

loadmodule "topos.so"
loadmodule "siptrace.so"

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_on", 1)
modparam("siptrace", "trace_mode", 0)
modparam("siptrace", "hep_capture_id", NODE_ID)

modparam("topos", "db_url", DBURL)
modparam("topos", "mask_callid", 0)
modparam("topos", "sanity_checks", 0)
modparam("topos", "branch_expire", 130) # 3 Min
modparam("topos", "dialog_expire", 10800) # 3 Hours
modparam("topos", "clean_interval", 60)
modparam("topos", "event_mode", 3)

request_route {
sip_trace_mode("t");
........
}

onsend_route {
    if (is_method("ACK")) {
sip_trace();
    }
}
==============

Thank you!

Kind regards,
Angelo
