I would agree with woofgang on this one. It's happened to me loads of times, and it's so annoying! As for the anonymous caller reject, I can see this would be very useful. On the other hand, though, apart from preventing nuisance calls, it could block an important call. I work in the NHS and have to sometimes ring people at short notice. Obviously, my call would be classed as anonymous and, therefore, blocked, which can be a nightmare if you're trying to get hold of someone to pass on urgent information. More than once I've had to ring on my personal mobile, and advise patients to remove their blocking facility if they are likely to be receiving further calls with regard to appointments or treatment. Just something to bear in mind.
