Hello,
I try to setup realtime monitoring.
Here is part of my script:
loadmodule "nathelper.so"
modparam("nathelper", "remove_on_timeout_bflag", "RM_ONTO_FLAG")
modparam("nathelper", "ping_threshold", 5)
.......
route {
.........
setbflag(RM_ONTO_FLAG);
.........
}
>From location tableI (cflags) I see "RM_ONTO_FLAG"
Unplug Internet connection from registered endpoint.
Opensips send sipping. Received "Destination unreachable (Port
unreachable)".
Record in location table is not deleted.
Where is problem?
Regards,
Dragomir

> * user experience - using the zombie registration to reach un-existing

> For usage perspective, the nathelper module now has two new parameters:
> * ping_threshold - timeout to consider a ping as unanswered;
> * max_pings_lost - the number of unresponded pings after which the
> contact is
> removed from usrloc;
> In order to activate this feature, every contact must have the
> sipping_bflag
> (to be pinged) and remove_on_timeout_bflag (to be deleted on no-answer)
> activated.
> This means these flags must also be configured in the nathelper module. [0]
