Received call to my cell phone at 2-2-10 10:58 AM PST. I did not answer and let it go to voice mail. I checked the voice mail message but they/it did not say anything. I called the number back using my work phone so there is no way they would have my personal number. Also, my outgoing calls from my work phone do not show my inbound number on caller ID. Anyway, all I got was, "I'm sorry. The number you have reached is not in service."
