this is the trace I get. I don't see much more than I posted earlire( I had filtered on tm)

in this one I see acc module, but no acc is loaded

acc [acc_logic.c:721]: tmcb_func(): acc callback called for t(0x7faf932f42c0) event type 512, reply code 404

this line is the first for noting a 404, could it be an accounting issue?

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?
