Hi Davy,

we're using siptrace with kemi and python 2. I can not confirm your problem on kamailio 5.2.2.

In difference to your script, however, i'm not setting a target address in the invocation.
Instead the cfg script sets modparam("siptrace", "duplicate_uri", "sip:<myhomerip>:9060") and uses KSR.siptrace.sip_trace()

Maybe it makes a difference, can you try it out?

Regards,

Thomas
