Annoyed by phone calls from unknown or private numbers? Don't want your girlfriend/boyfriend calling while your spouse is home? Do Not Disturb gives you the power to automatically block unwanted callers, sending them straight to voicemail. You can choose from 4 different call blocking options; specific numbers, unknown numbers, private numbers, or set a time frame in which all calls will be sent to voicemail. When activated, the application screens the incoming call, decides if the call is wanted, and either cancels the ringer or allows the call based on your preset parameters. Do Not Disturb is a great solution for those plagued by telemarketers, or those of you who want just a little more say on which calls come through to your device. Its available for $6.99 untill Mid-December and supports all devices.
