Who called from 6082561901

I just got a call from that number, and the message left said it was from the Madison VA

Caller ID says "US Government". Looked up the number online and it says that it's a VA Hospital.

Yea, it's a VA hospital in Madison, WI.  Very mysterious, can't imagine why they would call me.

I eceived calls from this number plus 608-249-0399 and 608-256-1662. When I answered they said they had a gift certificate that wasn't use and I said I wasn't interested and they hung up on me. I called the number back and it says by recording that the number is disconnected. The calls were from Madison WI.

It's the Madison VA scheduling desk; I think they are just misdialing.
