Application to interact with a unified communications server

We are looking to design a small smartphone application that allows on-the-road interaction with our unified communications solution. This project does not require designing any media processing. It is a fairly simple application that connects to our server's REST interface and is able to display information the user needs. The product you will be working on will be a very attractive solution used widely to communicate, including IM, voice, video, collaboration and social business, all based on unified and rich presence. Project documentation will be made available upon request. We work with a small international team and well established processes and tools to accommodate remote members. For the duration of the project you will become a key member of this team and we will value your opinion and input.
