But, might have a problem with Pp flag if a UAC don't reply to

<div dir="ltr">Hi all,<br>
<br>
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. <br>
<br>
I have the following problem, when a network
failure occurs those dialogs keep on and this
generate errors. <br>
How can I avoid this and remove those dialogs?<br>
<br>
Note: I don't know if it can be useful but
'Failure Route' is performed shortly after the
failure.<br>
<br>
Thanks.<br>
Regards.<br>
