NT server needs for placing return calls

By default, callback is disabled and no Windows NT server callback dial number is
configured.
2) Configure the PPP callback server in the C-DCC implementation
The callback server can originate a return call according to either the network address
configured in the dialer route command (PPP authentication must be configured in this
case), or the dial number configured in the service-type ppp command. Therefore, the
user must configure either method in the dialer callback-center command for placing
the return call.
The user should configure the callback client user name in the dialer route command,
so that the callback server can authenticate whether a calling party is a legal callback
user when receiving its call requesting callback.
Use the service-type ppp command to configure the callback user and callback dial
number in local user view, and perform other configurations in dial interface (physical or
dialer interface) view.
