Hello Daniel, it works now: 0(22097) DEBUG: <core> [sr_module.c:625]: find_export_record: found <bind_textops> in module textops [/usr/lib/kamailio/modules_k/textops.so] Thanks! We are going to add some functionality to the siptrace module concerning distributed logging without writing the data to your local database. When using trace_send_duplicate we loose the information from fromip_column, toip_column and direction_column as well as the exact time. So we need to send this information, too. We have two approaches. First approach: Instead of writing the data to the local database send all the database fields in one udp paket to another server and write them into database there. Second approach: Add 4 header fields containing the information to the sip-message and send the SIP message to another Kamailio server using trace_send_duplicate. There remove the 4 Header fields and write into the database. Do you think there is a better way to achieve this?

I just committed the fix on GIT master branch (devel version): http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=db188fbc f4d752a2afab2e298a2f081f836d7e92 I couldn't test it for now, so if you can give it a try and report whether it is working ok or not, then I can backport the fix to 3.1.
