I've been receiving quite a number of calls from this phone, they do not leave a meessage of any kind so I can only guess that it's a premeditated call to check to see whom is at home or not. I have call this number and the answer machine will answer and will say that the system is full and can't take any more calls.
I believe this is another number from a Solar Power scammer. CID shows Glendale CA They also use 818-296-0002, 818-330-5140, and 818-154-7522. Seems that they all have the exact same "mailbox is full" message when I call them back.
You're right....it is useless. Most of the Solar Power asshats have told me that they don't even bother to check the DNC registry. And why should they? Nothing happens to them if they violate it. I've seen an ad online for people to make these calls. There is no brick and mortar building. Anyone with a phone can make these calls. If I had my way, when these guys call, a fist could pop out of the phone and punch them in the voicebox.
