[SR-Users] Dialog - timeout for dlg with CallID

Hello,
I changed the configuration file to call dlg_manage() for all methods:
if (loose_route()) {
dlg_manage();
if (is_method("BYE")) {
setflag(FLAG_ACC);
setflag(FLAG_ACCMISSED);
$dlg_var(billsec) = $DLG_lifetime;
}
route(RELAY);
exit;
};
but, unfortunately this is not helping either. I'm not sure that there is a
buggy UA messing RR because this is happening with 4 Providers randomly.
What else I noticed is that this is happening mostly with ISP's using
authorization, with other ISPs using IP as whitelisted source I didn't
notice anything like that.
Could this be related somehow?
Thanks.
