Hello list,
under special circumstances I have a problem with the DIALOG module of SIP-Router/Kamailio
version 3.0.2. The dialog module is used in combination with presence, presence_xml, pua,
pua_usrloc and pua_dialoginfo modules + db_mysql modules. The db_mode is set to
"write_through", because of redundancy requirements.
From my point of view this problem has something to do
with timing in general. E.g. a so called "data call" has a duration of about 50
ms only; INVITE....BYE). That problem occurs on this short calls only. Because of the
problems in the dialog state machine, NOTIFY messages are incorrect. Even when the call is
already finished, the NOTIFY message includes the state "confirmed" and causes a
wrong status indication....
The detailed error message can be seen here:
"Jun 9 16:00:39 debian /usr/sbin/kamailio[14992]: CRITICAL: dialog [dlg_hash.c:591]:
bogus event 6 in state 2 for dlg [dialog-ID] with clid [Call-ID] and tags
'1299370188-28358304-1276092068837' ''"
I found in old mails of the developer list another error that looked nearly the same, but
it differed in the event and state of the dialog state machine (the thread can be found
under the link http://www.mail-archive.com/devel@lists.kamailio.org/msg03234.html). That
bug should - according the information that I've found in the list - be solved.
Therefore I will ask you: is the error as displayed above another well known error / bug,
which (maybe) should already be solved? Is it a new bug?
Thanks for any information.
regards,
Klaus Feichtinger
