Hi Flavio,<br>
<br>
According to the RFC, the callee side must not send a BYE for a
dialog in early state. <br>
I have just edited the dialog state machine to no longer log BYEs
from the caller's side for dialogs in early state as bogus.<br>
<br>

<div>I had the same issue recently, I have captured some packets
at the same exact time of the messages. In some cases, if your
system becomes unresponsive for a few seconds, CANCELs were not
relayed by the proxy (actually I saw several requests without
any reply for some time). Then, the other side sent a BYE (some
sort of timeout I believe) in early state because it didn't
receive the CANCEL request. This was happening because of a
MYSQL stored procedure (billing) closing records in a large
database with millions of acc records, mysqld was going to 100%
and blocking the system. I stopped the stored procedure and the
system stopped presenting these messages. So, maybe this is
something to worry about. I hope you don't have the same issue,
but I believe it is worth to check. </div>

Hi Jan,<br>
<br>
I was just saying to Max (see the other email) that BYE
instead CANCEL seems to be according to RFC; and as the
dialog module has nothing to do on a BYE in early state, we
could simply remove the error log and let the callee to
decide if the BYE should be accepted or not.<br>
<br>

Bogdan

Bogdan,<br>

Thanks for the quick reply. I understand my
programming at least is OK. The<br>
critical log entries are just inconvenient when
reading the log files.<br>
Returning a 501 works for x-lite, it then comes back
with a Cancel. If not<br>
returning a 501 strange things happen (INVITE to
failover etc).<br>
<br>
I only see the problem only with x-lite clients. Do
you know that sending a<br>
BYE before a Cancel is 'wrong'? If so I can open a bug
report with X-lite.<br>
<br>
Gr.<br>
