There are two methods to activate call forwarding. The first is exactly the same as on an analog line, i.e.,
you pick up the handset and dial the access code assigned by your telephone company and the number that
you want the calls forwarded. Check with your telephone company for this access code.
The second is with the “phone flash” commands where you pick up the handset and press the flash key
before dialing the following:

The Prestige sends a single short ring to your telephone every time a call has been forwarded (US switches
only).
