Hi Amin,
welcome to the Plantronics Developer Community. As a start, after you dowloaded and installed the SDK download the following items from this site to help you get started:
- Spokes 3.0 API Reference
- Spokes 3.0 Developers Guide
- sample codes MobileCall, MobileCallNative that are companion to the Developers Guide
The Developers Guide has 2 samples, one in COM C++ and one in Native C++. This document has detailed step by step instructions how to build the samples.
If you are running samples in COM C++ you must have Spokes running in the background. If you have Spokes installed, it will be launched when Windows is launched. However if you installed the SDK instead, you must launch Spokes manually.
The above material is sufficient to get you started and I am sure you will enjoy working with our SDK.
