Programmer's guide

The most important parts of Yate are described bellow and also some libraries used to communicate with Yate.
The purpose of Yate is to provide an extensible telephony engine. Holding the base code as simple as possible and adding functionality as needed allows one to find the best balance between desired functionality, performance and stability.

Yate is a next-generation telephony engine; while currently focused on Voice over Internet Protocol (VoIP), its power lies in its ability to be easily extended. Voice, video, data and instant messaging can all be unified under Yate's flexible routing engine, maximizing infrastructure and communications in business.

The software is written in C++ and supports scripting in various programming languages like PHP, Python and Javascript.
