Figure 5-28: Phone Setup page
If callback is supported by your ISDN service and the remote office you are
connecting to, you can enable callback on the router. This means the remote
office router will call you back immediately when you call it, reversing ISDN
charges.
5. In the “Phone Setup page” on page 56, enter the local telephone numbers
allocated to you by your ISDN provider. These are the telephone numbers
that people will use to call you. If you only have one number, leave the other
blank.
6. Choose whether or not to enable callback on each phone port.
7. Select whether you want both phones to ring when either number is called,
or only the phone on the port with number called. Click the
OK button.
