1/23    I'm trying to track down and/or minimize the number of fax calls
        to my number. I've used Selective Call Blocking and have blocked
        about 8 numbers so far and it worked for a few months but lately
        I've been getting calls from Private Callers. What are some other
        options I have? Is Call Trace useful when you don't know who is
        calling you? Thanks.
        \_ Block private callers.  Why should anyone need to anonymously fax
           you?
