Anonymous call rejection

Anonymous call rejection is a landline calling feature which screens out calls from callers who have blocked their Caller ID information. Anonymous Call Rejection is based on caller ID (not automatic number identification or ANI). It is often free with caller ID on landlines. This feature is normally included with Caller ID, but may be available separately from the local telephone company. The ACR feature is not available in all areas.
