from the menu bar, select Advanced > Dial-up Preferences. In the Dial-up Preferences dialog box,
click the Callback tab and do one of the following:

After the PPP authentication is passed in a call, this option prevents the callback server from
disconnecting the current connection and calling back. Instead, the server will maintain the
current connection and allow the client to access the LAN or the Internet.
{ Select the Ask me during dialing when the server offers option.
The callback server will use the callback number you entered to place return calls.
{ Select the Always call me back at the number(s) below option.
The callback server will always place return calls at the number or numbers already set.
