Received "message" from this at 10:10 am, 03/24/13, a Sunday morning, on my land line answering machine in Concord. At least 2 solid minutes of dead silence. Weird.
Two days in a row now received calls from 925-134-5678.
Long pause then "Goodbye".
Tried calling back and received recording, "We're Sorry, Your call could not be completed as dialed".
I didn't know a phone number could start out with a "1".
This is starting to sound like a some sort of phishing or spam call.
