I answered this call to see if I would get the normal hang up I usually do with these strange area codes, however it also came up on my phone as VOIP and it was for a free home security system, but you must do these certain things in order to receive it, garbage! I don't know why I continue to get these recordings and calls where they simply hang up on me. I get at least one a day! I just block the number, but more always pop up. I'm registered on the Do Not Call list, but seems these robo calls are not included in this? So annoying!
