Dont believe the hype about Extreme Call Blocker, Mr Number or Call Control, those apps are not the only ones that work on Gingerbread - RCB functions on any Android version 2.1 and up, is much faster and 100% silent.
This app does not control your voicemail service. If your blocked calls are being sent to voice mail, try another blocking method or use Google Voice. You can simulate a disconnected message by forwarding busy calls to a number that doesn't exist.
OUTGOING CALL permissions are needed for obfuscation mode, refer to the Help for more information on why, possibly free hat racks for your tin hats.
ACCOUNTS are needed for Google contact Groups.
SEND SMS needed for auto-replies, SMS routing and obfuscation.
INTERNET ACCESS is for licensing, Flurry and the "Write to us" feedback tool.
LOG DATA is only sent with your permission via the "Write to us" menu item in Settings. You do not have to send anything if you don't want to.
