JCBloc
Android Telemarketing (Junk) call blocker
This program listens for an incoming call and captures the call's number. It then compares that number to numbers stored in a blacklist. If a match is found, it blocks the call after one (short) ring. If the user has voicemail turned on, the caller is directed to leave a message there. See the README.txt file for further details. Designed to work with Andriod 2.2.
