I hope to get the time to look into it either this evening or over the
weekend. I have some other logs sent to me for a dialog issue.

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.

Yes, that solves the problem here as well.
Thanks,

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users Hi Jan!
I replaced dlg_manage with setflag(dialog flag). This way the
dialog is
created only when a transaction is created. It solved my problems.
