Thank you for looking at this Power. I've tried most of the call blocker programs in the repos and you're right, none of them are perfect.

I get on quite well with Crochiks MyContacts, but although it is supposed to have the facility to block calls where the number is withheld, this never seems to work properly for me.

I'd like you to consider adding a feature to block calls where the number is either unknown or withheld in addition to phonebook numbers and black/white lists.

A register of blocked calls within the interface would be handy too.
