Just called the number and there is a message explaining who and why you received the call. Essentially this is the automated appointment reminder service from Hampshire Hospital you will not be able to interact with it if they leave a message. So you will need to answer when they call you again.

5 messages on my answerphone from this number - a recorded voice saying, "This is a message for Mrs........(with my name). To retrieve your message, please press any key on your telephone keypad" I am skeptical and wonder it by pressing a key this would connect me to a premium rate number. I did wonder if this was Test and Trace, but I have the NHS Covid app so think I would be contacted via that.
