Description
Use the ppp callback ntstring command to configure the dial number required for a
Windows NT server to call back the router.
Use the undo ppp callback ntstring command to cancel the configured callback dial
number.
By default, no callback dial number is set for the Windows NT server.
When a router functions as the callback server to call a Windows NT server, this
command should be configured if the server needs the router to send the callback
number.
Related command: ppp callback.
Example
# Set the dial number for a Windows NT server to call back the router to “2489”.
[3Com -Dialer1] ppp callback NTString 2489
