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.
