The Everyday Phone can block 20 individual numbers, meaning that you really can avoid speaking to the people you don't want to.
Do Not Disturb
For those times when you just want some peace and quiet, switch on Block All so that your phone won't ring. If you want key friends and family to still get through, they can do, by tagging them as VIP's in your address book.
