Hello Daniel,

thanks for the fast reply.

i changed the loadmodule order (siptrace.so before topos.so) and its the same behavior. With sip_trace_mode("t");

For better understanding I attached the loading-part of my kamailio.cfg with siptrace and topos. The howl request route is not included, but didnt matter imho.

Cheers Karsten

Hi Daniel,

in that case it works (also with topos and then sipcapture). With your suggestion.

In my other case (as webrtc and tls registrar) I needed the function to see Kamailio self created traffic and so, imho.

Thanks for the hints.

Cheers Karsten

Hello,

to get what is received from/sent to network, you have to use:

modparam("siptrace", "trace_mode", 1)

And no longer use siptrace flag or functions in configuration file. In the configuration file the sip message is the one after topos handled the incoming message and before topos handles the outgoing message.
