Hi, all. Today we’re happy to share some excerpts from the recently published Programming for Unified Communications with Microsoft Office Communications Server 2007 R2 (Microsoft Press, 2009; ISBN: 9780735626232; 416 pages), which comes directly from the Microsoft Office Communications Server product team. This post includes the book’s About the Authors, Contents at a Glance, Introduction, as well as a stretch of text from Chapter 2, “Microsoft Unified Communications APIs Foundation.” I’ll keep this intro text short because much follows.

Why We Wrote This Book
Microsoft Office Communications Server is a relatively new product. Although it has its originsin the Enterprise Instant Messaging products, such as Exchange Instant Messaging,Live Communications Server 2003, and Live Communications Server 2005, it has evolved tobecome a comprehensive platform for all real-time communications. The current release,Office Communications Server 2007 R2, not only supports enterprise instant messaging (IM)and rich presence, but also offers a powerful Voice over Internet Protocol (VOIP)–based telephonysystem, multiparty audio conferencing, Web conferencing, and application sharing.
This server offers tangible benefits in direct cost savings (for example, by eliminatingcostly audio conferencing services provided by telecom carriers) and improves productivityby providing more efficient ways for people to contact each other. Office CommunicationsServer is one of the fastest-growing server products in Microsoft history, with tens of millionsof licenses sold.
Office Communications Server is a software-based solution that runs on standard computingand networking hardware. This server offers a rich, open API platform, making it an openand extensible part of the Microsoft Unified Communications (UC) platform. There aremany opportunities for developers to build new applications on this platform. We knowthat developers are looking for resources to help them develop applications using the UCAPIs, and this book is the only one on the market today that addresses this need. Written byexperts from the product group, Programming for Unified Communications with MicrosoftOffice Communications Server 2007 R2 offers an easy-to-read exploration of the APIs. Wehope it serves you well.
What This Book Is About
This book is organized into five parts.
Part I, “Understanding Unified Communications,” introduces the UC platform and providesan overview of the APIs.
Part II, “Office Communicator Automation API,” explains the Office CommunicatorAutomation API in depth and provides a detailed walkthrough of an example.
Part III, “Unified Communications Managed API Workflow,” explains the UCMA Workflow APIin detail and walks through an example of a business process communication.
Part IV, “Unified Communications Managed API,” covers the Unified CommunicationsManaged API architecture and shows how to extend the Office Communications ServerEnhanced Presence model by using this API.
Part V, “Debugging, Tuning, and Deploying Unified Communications Applications,” explainshow to debug, tune, and deploy UC applications.
Who This Book Is For
This book is intended for developers who want to create enterprise applications that includecommunications functionality built on the UC platform. Familiarity and experience withMicrosoft Windows COM, Microsoft .NET Framework, and Windows Workflow Foundationdevelopment is recommended. This book is written on the assumption that the reader hasthis knowledge. Code examples in this book are written in C# unless otherwise noted. Forclarity and to better illustrate how to use the APIs, the code samples are not written withdefensive coding practices in mind. Please apply defensive code practices when reusing thesamples in your own production applications.
For an in-depth resource on the internals of Office Communications Server 2007 R2, see theMicrosoft Office Communications Server 2007 R2 Resource Kit (Microsoft Press, 2009), whichyou can purchase in a bookstore or order from http://www.microsoft.com/learning/en/us/Books/13113.aspx. That book also covers the Office Communications Server SoftwareDevelopment Kit (SDK), which is intended for administering and controlling complianceof the conversations (for example, ethical walls and custom disclaimers) with OfficeCommunications Server, and therefore is outside the scope of this book.
We sincerely hope that you find the technical information within this book useful andlucrative to your work.
This book features a companion Web site that makes available to you all of the code used inthe book. This code is organized by chapter, and you can download it from the companionsite at http://code.msdn.microsoft.com/programmingocs.

Chapter 2Microsoft Unified Communications APIs Foundation
This chapter will help you to:
This chapter provides a technical overview of the Microsoft Unified Communications (UC)APIs so that you can understand them, how they relate to each other, and what purposethey serve.
The intent of this chapter is to provide you with sufficient information to help you decidewhich UC APIs best fulfill your needs. If you already know which APIs meet your needs, youcan look only at the sections that cover the APIs of interest to you, or skip this chapter altogetherif you wish.
Unified Communications Managed API 2.0
The Unified Communications Managed API (UCMA) is a code platform managed byMicrosoft .NET Framework, which provides access to presence, instant messaging (IM),telephony, and audio/video (A/V). UCMA is a Session Initiation Protocol (SIP)–based platform.SIP is a signaling protocol that is used for setting up and tearing down multimediacommunication sessions. This API abstracts the details of the communication protocolsused by Microsoft Office Communications Server.
UCMA is used to build scalable middle-tier applications that work with OfficeCommunications Server 2007 R2, provide large-scale message throughput, and representmultiple endpoints. You can use this API to build the following types of applications:
More advanced applications include the following:
UCMA 2.0 is considered a middle-tier API written completely in C#. Therefore, it runsonly in environments where the .NET Framework is supported. It provides the followingcharacteristics:
UCMA 2.0 supports two types of SIP endpoints that are designed for distinct applicationscenarios: the ApplicationEndpoint class and the UserEndpoint class. You use theApplicationEndpoint class in applications that represent automated applications, such asbots that interact with users. You use the UserEndpoint class in applications that connectto Office Communications Server on behalf of users and perform operations on behalf ofthose users.
To configure Office Communications Server to trust connections from UCMA applicationsthat use the ApplicationEndpoint and UserEndpoint classes, the application provisioningprocess must define a Globally Routable User Agent URI (GRUU). For more informationabout GRUUs, see Chapter 9, “Preparing the UC Development Environment.” This is all thatis necessary if the application creates only UserEndpoints. After the application has authenticatedthe user, it does not need to supply those credentials to Office Communications Serverfor authentication. For applications that create ApplicationEndpoints, the provisioning processalso must create a Contact object that defines the application’s SIP URI. You also have theoption to create a display name and a TEL URI. The ApplicationEndpoint uses this Contactobject to register with Office Communications Server.
Examples of applications that use the ApplicationEndpoint class are Automatic CallDistributor (ACD), interactive IM or voice bots, and conference bridges. For more informationabout these applications, see the “UCMA 2.0 Workflow API” section later in this chapter.These applications use a Contact object to identify the application in Active DirectoryDomain Services. The Contact object specifies the application’s SIP URI and phone number.Examples of applications that use the UserEndpoint class are those that publish additionalpresence information. Examples of additional presence information include showing a GlobalPositioning System (GPS) location on behalf of a user or acting as a proxy when the user isnot available and routing incoming IM messages through a Short Message Service (SMS)gateway.
UCMA is composed of the following two interfaces:
This architecture can be represented as shown in Figure 2-1.
