Callback is a command string that is passed back to the access server. You can use 
callback strings to initiate a modem to call the user back on a specific number for 
added security or reversal of line charges. There are three options, as follows:

No callback allowed—Disables callback for this group’s users. This is the 
default setting.

Dialup client specifies callback number—Allows the dialup client to 
specify the callback number. The dialup client must support RFC 1570, PPP 
LCP Extensions.

Use Microsoft NT/2000 Callback settings (where possible)—Uses the 
Microsoft Windows NT/2000 callback settings. Note that, if a user’s 
Windows account resides in a remote domain, the domain in which 
Cisco Secure ACS resides must have a two-way trust with that domain for the 
Microsoft NT/2000 callback settings to operate for that user.
