I think the problem with 4.2.2. is the following:
After dialog cleanup code is not executed after script exit. Thus, if
the dialog is created without generating a transaction, e.g.:
...
dialog_manage();
... some checks
sl_send_reply();
exit;
the dialog is created, but not destroyed after exit. Thus, next time a
request with identical dialog IDs (e.g the second INVITE after
authentication) is received, Kamailio finds the un-destroyed dialog and
falsely think this message belongs to a spiraled request and thus does
not register the tm_callbacks for the responses. Thus, the dialog stays
in state 1 forever.
Probably there are 2 bugs:
1. The dialog callbacks are not executed on script exit (this works fine
in Kamailio 4.1.7)
2. The spiral detection code is buggy. Just because a dialog exists is
not a proof for a spiral. In fact, a request with only 1 Via header can
never be a spiraled request.
