Callback is a command string that is passed to the access server. You can use a 
callback string to initiate a modem to call the user back on a specific number for 
added security or reversal of line charges.

To set the user callback option, follow these steps:

Perform Steps 1 through 3 of the 

Result: The User Setup Edit page opens. The username being added or edited 
appears at the top of the page.

Under Callback in the User Setup table, select the applicable option. Choices 
include the following:

Use group setting—Select if you want this user to use the setting for the 
group.

No callback allowed—Select to disable callback for this user.

Callback using this number—Select and type the complete number, 
including area code if necessary, on which to always call back this user.

Dialup client specifies callback number—Select to enable the 
Windows 95/98/ME or Windows NT/2000 dialup client to specify the 
callback number.

Use Microsoft NT/2000 callback settings—Select to use the settings 
specified for Windows NT/2000 callback. Note that, if a Windows account for 
a user 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.

The dial-in user must have configured software that supports 
callback.
