Call Blocking features control your incoming calls:

Anonymous Call Rejection $4.55 / FREE on the LiteBlue Bundle
Use this service with Caller ID to reject anonymous callers — whose numbers are blocked from your Caller ID display. An announcement states that you do not accept anonymous calls and they can remove blocking and place the call again. Blocked, private and anonymous numbers are rejected. Calls from identified, unknown, out-of-area or unavailable IDs will ring through as usual.

To turn on the service, press *77. Listen for the confirmation tone, and then hang up. To turn off the service, press *87. Listen for confirmation tone or announcement. Hang up.

Per-Call Blocking — Free
Dial a code on a per-call basis to prevent your number from appearing on Caller ID.

To use Per-Call Blocking, press *67. Dial the number you're calling as usual. The person you've called will not be able to see your name and number on their telephone display screen (if they have Caller ID). Instead, a "P" or "Private" will be displayed, for this call only.

Per-Line Blocking — Free
Set your number to appear on Caller ID as "private." Or unblock your line to identify yourself. To unblock, press *82. Dial the number you wish to call.
