Blocked Call Warning. I always block calls from solicitors and junk faxes. Today, with a keyboard or mouse error, I blocked the number "1" as I was attempting to block a number and ended up blocking all incoming calls. This should not be a feature allowed or at least there should be a warning pop up that states doing this (or any other critical clicking around in the admin portal) will prevent all incoming calls from coming in. While I am a small business and I did lose a major client because of this mishap, what if I were I hospital or any other type of emergency service? This is really a serious flaw. There needs to be a failsafe for critical programming errors.
