Calling the number, I got an automated message saying it was AAMI.

I then called AAMI on the main number listed on their website and asked about this number. They couldn't confirm it was a legitimate number. I suspect this is some sort of fraud, someone pretending to be representing AAMI.

If they were genuine they would have left a message on the home phone answering machine. No-one rings us on our home phone except for cold callers so we don’t usually pick up. Suggest it is yet another phising call.

I have a missed call from this number no message left. I suspect it's a scam.
