Because of simul-ring feature of Vonage, I received the second call on my cell. When I activated "block caller" on the cell, AT&T gave me an error message, saying it waw not a valid number.
Same story from Arizona. I get about 1 call a day, they never leave a message, and when I try to call back I get dropped immediately into voice message with no info on whose number it is.
Received same call twice from a man whose Asian accent I could not understand. Said he wanted to give a free listing for my web site. He gave as a manager the name of a man who contributes editorials. I told him I don't want a listing. I suggest hitting them with a law suit based on the DO Not Call list.
Received a call from guy saying he was from Brandt(?) and wanted to give us a free listing. As soon as he was told he would need to talk with the office supervisor he hung up.
