Configuring Privacy and Security Features
You can also configure these features using your PC and the IP Phone Web
Interface. See “Blocking Caller ID,” on page 71 and the “Blocking Anonymous
Calls,” on page 71.
NOTE For the Cisco SPA 501G, configure these features using the IP Phone Web Interface
or use the star codes (described below).
Blocking Caller ID
You can block Caller ID from your phone so that your phone number will not
appear to the person you call.
Using the Setup button:
STEP 1 Press the Setup button.
STEP 2 Select Preferences.
STEP 3 Choose Block Caller ID and press edit.
STEP 4 Press y/n to choose yes.
STEP 5 Press ok.
STEP 6 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.
