Block anonymous calls
Hi. I am trying to set up my Asterisk box to block anonymous calls. I am having some grief from telemarketer calls to my number and I would like to block it. I see from my CDR's that some of my callers also have "unknown" in their FROM field. I would like to let them through. Only block the FROM "anonymous" that the telemarketers use. Have anyone here done it and
