Incoming calls

Quick question….I was out in the car today running errands. I saw an 800 number come as an incoming call (BT to my cellphone). I pressed the “hang up” button to reject the call.

For the next 5 or 6 times I got back in the car and started it, XM came on for a short while and I then saw on the radio another “incoming call” and I had to reject each one (no phone number showed each time). I had to reject each call.

Have anyone seen this type of behavior before?
