GNU Free Call 是一个全新的项目，用于组织内部的电话通讯服务，基于 SIP 协议开发的点对点呼叫网络，大部分使用c++开发并在GPLv2协议下授权使用，新的名称改为'GNU Telephony'。
GNU Call 项目，与Skype的主要不同点在于，它将使用P2P(点对点)SIP协议，所以该协议并不会依赖单个服务提供者。该组织希望创造self-organised呼叫网络，因没有单个的脆弱点，而提高安全性和可靠性。它是建立在现有的GNU SIP Witch上，该项目是一SIP 呼叫的服务器，提供管理和rout呼叫的方法。
为了创建替代Skype的开源软件，GNU Project 宣布计划GNU Call，该项目希望提供安全的在线呼叫给所有的用户，与流行的Skype VoIP服务竞争。
GNU Call的雄心不可低估，可就像很多评论员说的一样，要想抢占Skype 的市场，即使是最好的产品，也将是件艰苦的工作。
GNU Free Call is a new project to develop and deploy secure self-organized communication services worldwide for private use and for public administration. We use the open standard SIP protocol and GNU SIP Witch to create secured peer-to-peer mesh calling networks, and we welcome all participation in our effort.
GNU Telephony is a project to enable anyone to use free as in freedom software for telephony, and with the freedom to do so on any platform they choose to use. We also wish to make it easy to use the Internet for real-time voice and video communication, and in fact for all forms of real-time collaboration. Finally we wish to make it possible to communicate securely and in complete privacy by applying distributed cryptographic solutions. Our goal is to enable secure and private real-time communication worldwide over the Internet that is free as in freedom, and is also free as in no cost too!
