Removing default call minder service from landline
Hi, we have just realised that my elderly parents have the default call minder service on their landline which switches to answerphone after 3 rings. They've missed many important hospital calls recently as they can't call these numbers back. We'd like to be able to remove this service completely as they do not need an answerphone since they're not going out anywhere during this current crisis. Could anyone advise us please?
