What is Yate

Yate stands for Yet Another Telephony Engine, and like the name states it is mainly a telephony engine; while currently focused on Voice over Internet Protocol (VoIP) and PSTN, its power lies in its ability to be easily extended. Voice, video, data and instant messenging can all be unified under Yate's flexible routing engine, maximizing communications efficiency and minimizing infrastructure costs for businesses.

Yate can be used as a:

• VoIP Server
• VoIP client

  • H.323 gatekeeper

The software is written in C++ and it supports scripting in various programming languages (such as those supported by the currently implemented PHP, Python, Perl and Javascript libraries) and even any Unix shell. The PHP, Python, Perl and Javascript libraries have been developed and made available in order to ease development of external functionalities for Yate.

Yate is production-ready software and is easily extensible.
