Could you please perform the same experiment I've done in my first mail? I can reproduce it 100% of times.
Will do and report back as soon as I get to it.
Thanks a lot. BTW I'm using kamailio 1.5.4.
I was able to repeat your results with Kamailio 1.5 SVN: Whenever I issue "dlg_end_dlg" on a call in the "early" state, it will never get cleaned up.
The reason is that the reference counter isn't properly decremented. Normal calls where no BYE message is forced correctly drop to zero references and finally let the dialog module clean up the terminated call. However, with dlg_end_dlg-enforced calls, the dialog drops no less than one no matter how long you wait.
I know the error is somewhere within send_bye(), and I'm in the process of closing in. Will report again once I find the right spot and probably also provide a patch right away.
Oh, and by the way: Kamailio does deny sending out BYE requests for calls not in the "confirmed" state as of now. However, this check is done in the tm module called by the dialog module, and the latter passes to the former a dialog state of DLG_CONFIRMED *always*. That is, it doesn't respect the current dialog's state. I have no clue why but will certainly consider using the real dialog state to work around the module's current deficiencies.
