Re: 404 sent from Kamailio NOT from the script

Hello,

it should be no internal 404 response from tm, maybe from other modules
that you use. You can load the debugger module and enable cfgtrace to
see what actions from kamailio.cfg are executed and try to figure out
which one is generating the 404.

Cheers,
Daniel
