Sync contacts between Asterisk and countless other apps

Asterisk is a software implementation of a private branch exchange (PBX) that helps you establish and control telephone calls between devices, services, and destinations. Over time, Asterisk's functionality has expanded to include more than just traditional PBX-related code (such as call handling, conference calling), but now includes intelligent behaviour for voice applications including machine intelligence recording agent features on your phone system that intelligently routes incoming messages to the appropriate person based on what they can do with it immediately.
App is planned.
