Blocking Caller ID

You can block Caller ID from your phone so that your phone number does not
appear to the person you call.
Using the Setup button:
Press the Setup button.
Select Preferences.
Choose Block Caller ID and press edit.
Press y/n to choose yes (enable) or no (disable).
Press ok.
Press save.
Using the star code:
Press *67 before dialing the number. (Caller ID blocking will remain enabled until
you enter *68.)

Blocking Anonymous Calls

Blocking anonymous calls prevents calls with unknown Caller ID from ringing your
phone. (For example, if a caller set his phone to not display Caller ID, the call is
considered anonymous.) These callers receive a busy signal or message.
Using the Setup button:
Press the Setup button.
Select Preferences.
Choose Block Anonymous Call and press edit.
Press y/n to choose yes (enable) or no (disable).
Press ok.
