This number has called me on my cell phone several times the past week. When you answer, it hangs up. When you try to call back it is always busy. Filed a complaint @ Bandwidth.com, (800) 808-5150.
Whoever he is, called 3 times within last 90 minutes. I have to laugh, as I only heard one. Calls my landline phone which is my "junk" number. I use PhoneTray Free on the landline. Freeware program which requires a compatible dial-up style modem, and for the user to have Caller ID. There is also some hardware thing that will block unwanted calls. It is about $90. I am getting that soon. For the most part, if you put some effort into blocking these people, or getting them into trouble (which is what I hope happens to this guy), they can't harass you.
