seguridad en voip -Wahay

What is Wahay?

Wahay is an easy-to-use, secure and decentralized audio conference call application. It allows you to easily host and participate in conference calls, without the need for any centralized servers or services. We are building a voice call application that is meant to be as easy-to-use as possible, while still providing extremely high security and privacy out of the box. With Wahay you don’t only protect the content of a conversation, you also protect the fact that the conversation existed.
To achieve this, Wahay uses the Tor Onion Services in order to communicate between the end-points, and the Mumble protocol for the actual voice communication.
