From what you describe this seems to be related to transaction life in
delete state. If the dialog is not answered, it is not inserted in
dialogs list. It is kept attached to invite transaction.
I agree that state 3 should stay no longer than 32sec, normally this
should be clear by caller sending BYE due to non-ACK. You said you are
not doing record routing, how the bye gets then to the proxy so the
dialog is cleared from memory?
Cheers,
Daniel

I've checked and the same occurs when the INVITE transaction is

with a final [3456]XX response. In any case it remains in memory in state 5

Hi, using Kamailio 1.5.4.
I use dlg_manage() for an INVITE. 200 Ok is replied by the callee but
the UAC doesn't send the ACK (due to a crash).
The dialog remains in Kamailio dialog memory/table in state 3 and would
expire after default_timeout (which usually is 3600 seconds or more,
unsuitable for this case).
Yes, it could occur that the proxy is not doing loose_routing, but in
that case it doesn't make sense to use dialog module, so shouldn't
dialog module expire dialogs in state 3 after ~32 seconds?
I'm using profiles_with_value to limit the number of calls per user, so
this issue is a bit important, as a UAC not sending the ACK for a 200
means one less available channel for this user during dialog module
default_timeout.
Another issue: when a call is cancelled the dialog remains in memory
for
~4 seconds more.
This is:
- INVITE received and any provisional response => dialog in state 2.
- CANCEL received => dialog in state 5 for ~4 seconds.
Is there any reason for that?
