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

I have a problem where a call comes in and causing a 404 Not Found to be replied.
the script does not have a 404 reply set in it anywhere
unfortunately I cannot get the script to produce logs, hence my other post. But its making it tricky to find the source of the 404. following the script it should not be producing a 404, but doing a relay. I suspect there is something wrong with the tm or its not getting a result it needs.
It looks like the transaction module is triggering thge 404 somehow and Its showing up in debug below.
Does anyone have any ideas why i'm getting a 404?
version 5.6.6
Regards, Richard
