It is amazing what they are doing with mobile phones and land lines today. I received a phone call on my land line from myself. When you got this voicemail message did it give you the number from this person? I have heard of people doing this just to see if they get a response from that number. Then they were bombarded with calls from people trying to sell them something. I am getting so many calls on my cellphone from people I don't even know but at least I am able to block them. Most of them that leave a voicemail are from debtor that are calling for people that I don't know. As far as him having you arrested for harassment I believe it would be a lot harder for him to do that then it is for someone to spoof your number.
