I just called this number back and its from a lawfirm telemarketing, however, it gives you an option to press 2 to remove your number from their call list.
I received a call from this number twice a day for about a month. They always rang once and hung up without leaving a message. I finally got sick of it, so I googled the number and ended up here. I followed Tony's advice (the poster above me) and I'm happy to say that I've been miraculously cured of this horrific telemarketing disease. All I had to do was call the number back, and press the #2 button on my phone until I heard the word "Adios". It actually worked! I haven't received an unwanted call at 7am for about 5 days, and my doctor said I'm going to make a full recovery! Thank you Tony! Whoever you are.
I would also like to thank 800notes.com, Google, Dr. Swartz, Dr. Feelgood, and most of all my wife. I know, Tony should get the most thanks, but my wife buried all my guns in the backyard. I would probably be sending this message from prison if it wasn't for her. Plus, I don't think Tony wants to compete with the other things my wife did to keep me calm during my recovery.
