Hi Jorge,
Any SIP client must answer to an incoming request (even if it
understands it or not) - it must send back some reply. The dialog module
terminates the call if it gets a timeout (408) of 487
(transaction/dialog not found) from the client. Other negative replies
are not considered.
Usually, the risk is to have clients blindly answering with 200 OK to
any OPTIONS (even if the dialog does not exist).

Yes, the "B" flag was already configured (6 hours).
But, might have a problem with Pp flag if a UAC don't reply to SIP
OPTIONS messages?
Thanks.
Regards.

Or, be sure and set a reasonable dialog lifetime (like maybe 2 hours)
together with the "B" flag (to send BYEs one dialog timeout).

Hi all,
I'm using OpenSIPS 1.8. with several Asterisk. When Proxy SIP
manages a call keeps a dialog with (called,caller,Asterisk)
through store_dlg_value function from dialog module. Later
through get_dialog_info function it match calls and resolves
transfers issue.
I have the following problem, when a network failure occurs
those dialogs keep on and this generate errors.
How can I avoid this and remove those dialogs?
Note: I don't know if it can be useful but 'Failure Route' is
performed shortly after the failure.
Thanks.
Regards.
