The conaito VoIP Video EVO SDK contains a high performance VoIP and Video conferencing client capable of delivering crystal clear sound and video capturing even for both low and high-bandwidth users. Conaito VoIP Video EVO users are arranged in a tree-structure where each node is a room/channel where users can talk, see Users, send instant messages and share files.

Examples of such applications could be Internet phones, conferencing tools, surveillance systems, e-Learning systems, or any other type of application where audio and video transmission between networked clients is an essential part of the application.

The VoIP Video EVO SDK consists of both a client and a server. The VoIP Video EVO server is a standalone application which provides user authentication and keeps track of connected clients. It can operate in both LAN or WAN (Internet) environments. Each server instance is capable of serving 1000 simultaneous clients. A VoIP Video EVO client can connect to the server and can from there interact with other clients. The client is wrapped in a DLL file (.so on Linux) which enables developers to add the following features to their application:

• Multiple active real time audio and video streams
• Instant text messaging
• File sharing
• Tree structure for grouping clients
• Audio capture supported by DirectSound and WinMM
• Video capture supported by DirectShow
• CELT and Speex audio codecs for VoIP supporting both high and low bandwidth usage

… and much more!

The VoIP Video EVO DLL comes in two versions, one for development in .NET Framework using an object-oriented approach and one with a C-API for development in C and C++. Numerous examples are included with the SDK so developers can easily get started developing their own applications. Check out the documentation in the navigation bar to the right for a complete tour of the SDK's capabilities.

Having the above features available makes it simple to develop any type of VoIP- and Video-enabled application, like e.g. a teaching tool, live support, chat, meeting tool, a multiplayer game or any other type of application which requires users being able to talk, type messages and send files to each other.

For conaito VoIP Video EVO clients to be able to interact with each other they must connect to a conaito VoIP Video EVO server which keeps track of where users are located and forwards voice/video-data packets between clients (p2p is depending possibly!). The conaito VoIP Video EVO server is able to serve 1000 simultaneous clients and can be hosted in both LAN and internet environments.
