We received several call from that number and from numbers with similar area codes and prefixes; however, they didn't answer. From calls where I was not present they left no voice mail. Doing an internet search, it is determined that the calls are most likely some telemarketing scams, involving gifts, prizes, lotteries,  collection, credit, or some fraud. The best thing is to not answer, or if one is inclined to do something, report them for their gimmicks! Make life difficult for those hucksters!
