A lottery winner declined the call letting him know he had won $100,000 (£90,000) because it was an unknown number.
The winner only realised he may have won after checking his emails and then seeing a message from the state lottery.
This made him check his voicemail where sure enough, he had a message informing him of his good fortune.
The Michigan State lottery said in a statement: "The lucky player, who chose to remain anonymous, won $100,000 after he was selected in a random drawing that took place on August 31.
"He earned entries into the giveaway by scanning non-winning $300million (£270million) Diamond Riches tickets on the Michigan Lottery app."
The lucky winner, from Washtenaw County, Michigan, who chose to remain anonymous, said: "I received a call from a number I didn't recognise, so I didn't answer it and it slipped my mind."
The player, who is 56-years-old, added: "Later that night, I was checking my email and saw a message from the Lottery saying that I had won $100,000.
"As soon as I saw that, I remembered the mysterious call and listened to the message that was left.
"I am not sure I got an hour of sleep that night, I was so excited that I had won. First thing the next morning, I called the Lottery to schedule my appointment to claim the prize!"
The state lottery said that the player had recently visited the Michigan Lottery headquarters to claim his big prize. They said: "He plans to save his winnings."
For most people, winning the lottery would turn their life around.
A man preparing for important surgery accidentally bought too many lottery tickets - and won on every one!
The 67-year-old from Towson, Maryland, mistakenly purchased three identical tickets for the same draw last week.
He said he totally forgot he already bought one for the midday and evening Pick 5 game so grabbed another on a trip to the shops.
His wife, unaware that he had already collected tickets for the draw twice, bought him a third ticket later that day thinking he wouldn't remember.
Cursing the wasted money, little did he know he was about to seriously cash in on the mistake.
Using the same numbers for all three - 5-1-3-5-9 - he couldn't believe it when he scooped a total prize of $150,000 (£138,000).
"The one time that I accidentally buy three tickets, the number hits three times. It was unbelievable," the player told UPI.
But it's not the first time he has won big after scooping a huge prize on the four ball game a couple of years ago.
"I went to play my daughter's birth year, which is 1979," he added.
"The clerk at the store got it wrong and gave me the wrong number, 1997. When I got home later, guess what four digits hit that day? 1997!"
He says he plans to spend some of his recent winning on her after banking the huge prize from his error.
