Someone called from this number but failed to leave a message.  Kind of weird because if it was a bill collector or for a charitable cause they would have left a message.

Got a call from this number, but they left no message.  I called the number and it is a cell phone number with a Detroit, MI area code, but the message for that phone number says that it is not an assigned cell phone number.  My guess is that it is an illegal caller or some other sort of not reputable company offering a fake caller ID number.

Same what Tee & Eagle Idaho said.

Caller said something to herself and hung up.

Caller asked for me but I was not home at the time. She said in a soft voice that she wanted to thank me, but for what she did not say or my husband could not hear her.
