Very short ring, two days in a row. 7pm last night and just after 1pm this afternoon, I did not answer. I use the google search WHOIS-RWN to find who the caller is. This one turned up not traceable, so it is most probably a scam from another country that our government cannot at this time stop. Unless your number is on one of your known call lists (help groups etc...) DO NOT answer a number you can't identify.
