This tab contains the configuration controls that the eWON will use to perform callback operations.

Control Description
General Callback Config
Callback enabled
If this box is checked, then the eWON callback feature is enabled. This means that the eWON can be
triggered by an external event in order to call a given phone number in order to establish a PPP link.
This permits to let the eWON’s phone line pay for the call, with a budget maintained by the eWON
itself. This also ensures more security if you are calling back a private server.
Do not forget to enable outgoing calls in the dialup configuration.
Callback delay
Once the eWON has been triggered, it will wait for this amount of time before dialing out.
This is useful in order to release the phone line or perform any other action.
Wait for user login for
Once the eWON has been triggered, it will wait for this amount of time in order for the user to log-in.
Otherwise, the call is dropped. It is clear that this delay has to be greater than the sum of the callback
delay and the call establishment.
Dialup account
This list box permits to choose the server used for callback. The "User’s request account" option can
not be chosen when the trigger mode is "Ring", because the eWON does not know the server data at
this time.
