Wow, what jerks. I just got a voicemail message on my new (5 days old) VoIP (Voice over Internet Protocol) system. The calling number was recorded as 1-770-368-1185. The call came in on Thursday September 8, 2005 at 9:02pm, which is also a violation of the Telephone Consumers Protection Act.
This is very similar to the system described at SEC Instant Classic #1: Fraudulent Wrong Number Stock Tips.
