<tt>Hi Samuel,<br>
<br>
For dialog module, the primary storage (for dialog info) is all
the time the mem cache. DB is only a secondary storage and data is
flushed from mem to DB. At runtime, opensips never reads from DB,
but only from mem (the primary storage). (db mode REALTIME means
the DB storage is updated in realtime from mem cache)<br>
<br>
So, you cannot have 2 opensips sharing dialog info via DB. Or you
want to implement a failover kind of scenario (like shifting
dialogs from one box to another) ?<br>
<br>
Regards,<br>

<br>
I'm started reading about dialog module and how to use it in a
distributed environment. I've read about the 'B' flag and how it
can be used to send BYEs to the end-points. My question is
whether, using db_mode REALTIME, another instance of opensips can
use the information stored in the database to send the BYE to a
dialog created in another opensips instance. <br>
<br>
The scenario is the next one: <br>
1.several opensips sharing the database and one of them receives
an INVITE.<br>
2.It creates the dialog and sets the B flag. The parameter timeout
is then set to the corresponding value. <br>
3.Another opensips uses the information from the dialog table to
send the BYE either forced by an external t_dlg command or reading
from the database (I guess the period can be controlled with the
db_update_period parameter).<br>
<br>
Is this possible with the current version?<br>
<br>
Thank you very much in advance and congratulations,<br>
Samuel.<br>
