Pattern Call Blocker

Be in control of your phone and automatically reject spam calls!
Create a reject list of numbers to block and manage this simple call barring app.
Grow your blacklist and customize the actions to be performed.
This open source and free application blocks unwanted calls on a rule-based logic, with number pattern recognition.
When an incoming call is detected, the service loops through the list of active filters,
and for each filter, when there is a match, a custom action is performed, like dropping the call,
logging the event or sending a warning message.
A filter is assembled by combining two rules and one action: a calendar rule to define
when the filter is active, a filter rule to define the numbers and patterns against which
the incoming call is matched and an action to be performed when the filter is active and
there is a match.
It is now Open Source and available on GitHub!
