The Conaito VoIP EVO Mobile SDK provides the documentation, samples and related libraries you need to integrate with other applications or systems. The SDK contains a C-API DLL and a COM control of the VoIP EVO client that can be used from any programming language C++ and .NET Compact Framework.

Both VoIP clients have been compiled for Pocket PC 2003 and Windows Mobile, which use intruction-set ARMv4 and ARMv4I, respectively. Note that it is not possible to connect to a VoIP EVO server if the WindowsCE and Windows Mobile device is running under Microsoft ActiveSync. This is because ActiveSync doesn't support UDP packet transmission. The same goes for the Emulator images which comes with the Pocket PC 2003 SDK and Windows Mobile SDK.

The Conaito VoIP EVO Mobile SDK has been tested with Embedded Visual C++ 4.0 and Visual Studio 2005. Using Visual Studio 2005 is highly recommended since it comes with an ARMv4-based Pocket PC emulator. Currently there's not a VoIP client available which will run with the emulator for Embedded Visual C++ 4.0 (which uses a x86 instruction set). The API of the VoIP clients and are the same as for the clients in the VoIP EVO SDK, except that Windows CE and Windows Mobile uses Unicode (WCHAR instead of CHAR). The Server-folder of this SDK contains the standard VoIP EVO servers which runs on Win32 and Linux.

The contents of Conaito VoIP EVO Mobile SDK and the supported development environments include all of the necessary software components for building systems based on Conaito VoIP EVO Mobile SDK including documented operational software applications, examples (with source code), explanations as well as necessary service programs, libraries and components.

The supported development environments include:

• Visual Basic .NET (.NET Compact Framework)
