9.7 Call Forwarding
Call forwarding means the switch will ring another number at a place where you
will be when someone dials your directory number.
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.
The second is with the “phone flash” commands where you pick up the handset
and press the flash key before dialing the following:
