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.
To block anonymous calls:
STEP 1 Log in to the web interface.
STEP 2 In the
Voice
tab, click the
User
tab.
STEP 3 Under Supplementary Services, locate the Block ANC Setting field.
STEP 4 Choose
yes
or
no
to enable or disable.
STEP 5 At the bottom of the page, click Submit All Changes.
