Busy signal.  Unsolicted.  Been getting a bunch of robo calls from Oregon lately

Unknown. Called, left no message.

@ Utah Skeptic --- indeed, I have been getting a lot of calls from Oregon myself, they call, never leave a message.

Got a call from this number at my work; they did not leave a message

I've received two calls today from this number at work. They did not leave a message. It's too bad my outgoing message that they're calling the legal department of a large company didn't scare them.

I've received 3 calls from them at work. I answered and they hung up each time...So I take it nobody knows who the number belongs to?
