Called my cell - 2 rings, hung up. 10 seconds later, the same number called my husband's cell and left a voicemail. It was a travel agency. He deleted the message.
I sent the call to voicemail because I didn't recognize the number. There was a recorded message about a trip. I too am on the do not call registry. If I want to travel I'll find my own travel agent thanks. This borders on the line of harassment.
