Received multiple calls over the past two weeks. Caller from the Portland Oregon area never leaves a message. When I called back (twice) there is no voice mail or answer.

Received multiple calls over the past two weeks from this Portland area number. They never leave a message.  When I call back no person or voice mail ever answers.

Been getting calls from this number once a day for a week. Never leave a message. I've never called them back, which makes me the callee, them the caller.

Left long message on machine that was just people fooling around, like a "pocket call". Called number back and recording said all were busy, but the next available would help me. No one ever did, nor did they identify their company.
