QuiteSleep is an application for Android 2.0+ which manages your incoming calls

when you're busy, sleeping, or doing anything between two time slots in any day

of the week. QuiteSleep can block a list of callers or even other different

incoming calls and send an SMS or e-mail with a predefined text to notify you're

busy, sleeping, etc.

Four different ways to allow who can call you:

1) block all; 2) block only blocked contacts; 3) block unknown 4) block unknown

and blocked contacts
