Unknown caller on my unlisted phone tonight. I did not recognize the number, so I did not answer. The unknown caller did not leave a voice message. There are 14 complaint reports (across 3 sites) on the internet since May 9th. No one knows who this is. When they answer the callthey are met with total silence. Is that not weird? Anyway, given this reported annoying behavior, Ichoose to block this caller rather than to be bothered with repeat calls.
