Hello,
If you think there is a bug in the tm module, you could create an issue in our \
tracker here: https://github.com/kamailio/kamailio/issues/new?assignees=&labels=&template=bug_report.md
Please also add some description of the wrong behaviour that you are seeing in the \
server to it.
Thanks,

Subject: [SR-Users] bug in tm module?
Hello
I'm running K5.5.3 and have checked the 'issues' link in github and saw nothing \
regarding what I am seeing. I think that there is a bug in the tm module with \
respect to the "tm:local-response" event route. In the "t_reply.c" file, there is a \
static variable called '_tm_local_response_set_lookup'. This variable is initialized \
at load time to zero. It is checked in the '_reply_light()' routine and will \
initiate a local callback from the config script if "armed". The problem as I see it \
is that if the callback is readied, the variable is set to one. But it is never \
reset. So the practical outworking is as follows. A register is received and the \
request_route arms the callback. The register requires an authorization (local \
database sqlite). After the 401 is sent back, the callback via the module event \
route is called as expected. All good except that the module event route script \
fragment is never executed again after the first call. I'm no expert on the tm module \
but I would think that somewhere in there, the variable should be reset to zero so \
that subsequent transactions can initiate the event route again.
thanks for any help,
Dan
