Got a call from this number. No voice message left.

They call and never leave a message

Called and did not leave a message

Man with a southern accent called at 7:22 pm asking for Brian.  I told him he had the wrong number and it was pretty obvious he knew there probably wasn't a Brian here.  He immediately went into his pitch "Maybe YOU can help, I'm with [some veterans organization]..."  Doubt it's a legit organization, so I blasted an air horn in his ear, hung up and blocked the number.

They called at 9:30 am left no message, may be a telecommunication co out of Boise, ID according to reverse look up. I don't use VOIP so no reason for them to call me.
