The caller did not speak after I answered the call and hung up. When I called back a recorded message said,” the number you have called is not available from this service”
I suspect robo call or telemarketer. I’ve blocked this number

Has to be a scammer, the old " you missed this caller who didn't leave a message " ploy.. Same attempt occurred yesterday.. Added to the growing Blocked list..

Caller: Scam

Picked up the call, confirmed your name, then hung up..
Do not pick this call up!
