Who called from 3074622585

I have received at least 4 calls from this numberin the past 2 days.  My husband answered this afternoon and they asked for me.  They would not give him any information or leave a message for me.  Said they would call back since they needed to speak with me and only me. We don't know anyone in Wyoming, however, we recently made hotel reservations in the state for later in the year,  This number is not the hotel number.  Sounds like a scam of some sort.

I have received 5 calls from this number this week.  When you pick up no one answers.

3 days in a row of calls from this number - they leave no message.

Receiving 1 to 2 calls a day. They never leave a message on my machine. They;ve been calling for a week now.

Call and when answering machine answers no message is left. Caller ID reads: "Wyoming".
