Parameters
remote-number: Specifies an ISDN calling number, a case-insensitive string of 1 to 30 characters.
The asterisk (*) is allowed as a wildcard that matches any character.
callback: Enables callback for the specified ISDN calling number.
Usage guidelines
A dialup interface screens an i ncoming call by comparing the calling number with the numbers
configured in the dialer call-in command. If the remote SPCS does not provide the calling number,
the call is dropped directly.
On a dialup interface configured with the dialer call-in callback command, you must configure the
dialer route or dialer number command. The dial-number configured in the dialer route or dialer
number command must be the same as the remote-number configured in the dialer call-in
callback command.
Examples
# Configure BRI 2/4/0 to place return calls for ISDN calling number 8810152.
<Sysname> system-view
[Sysname] interface bri 2/4/0
