Office Communications Server 2007 R2 follows the Server/Client Access License (CAL) model. Under this model, an Office Communications Server 2007 R2 Server license is required for each operating system environment running Office Communications Server 2007 R2 Server. A CAL is required for each user or device accessing the Office Communications Server 2007 R2 Server. You can acquire Office Communications Server 2007 R2 as standalone server and Client Access licenses (CAL) or you can purchase the CALs as part of the Microsoft Enterprise CAL (ECAL) Suite. Microsoft Office Communicator 2007 R2 is the client software used to interact with the Office Communications Server 2007 R2 Server and is licensed separately as a standalone license, or available via Office 2007 Pro Plus and Office 2007 Enterprise.
Server Offerings
Standard Edition requires that primary server components, as well as the database for storing user and conference information, be configured on a single computer. Standard Edition is recommended for organisations that do not require higher availability through clustering.
Enterprise Edition enables separation of server functionality and data storage to achieve higher capacity and availability. Enterprise Edition is recommended for organisations that require higher availability through clustering.
The table below illustrates the additional new features contained within the Office Communications Server 2007 R2 CAL editions:
The Office Communications Server 2007 R2 Standard CAL is a prerequisite to the Office Communications Server 2007 R2 Enterprise CAL. Both versions of the CAL may run on either version of the server. Additionally, both Office Communications Server 2007 R2 Standard and Enterprise CALs are components of the Microsoft Enterprise CAL Suite.
Client Software
Microsoft Office Communicator 2007 R2 is the client software used to interact with the Office Communications Server 2007 R2 Server. Office Communicator 2007 R2 is available as both a stand-alone product and also included in the following Office System offerings: Microsoft Office Pro Plus 2007 and Microsoft Office Enterprise 2007.
If customers had Software Assurance (SA) on Office Live Communications Server 2005 CALs and Office Live Communications 2005 Server at the time of the release of Office Communications Server 2007 CALs on the Volume Licensing pricelist (September 1st 2008), and have maintained active Office Communications Server 2007 Standard CAL SA through the release of Office Communicator 2007 R2, they will maintain their rights to install Office Communicator 2007 R2 without purchasing Office Pro Plus 2007, Office Enterprise 2007 or the Office Communicator 2007 R2 stand-alone license.
CAL Use Scenarios
One licensing change from Office Communications Server 2007 to Office Communications Server 2007 R2 is to change the requirement for a CAL. In Office Communications Server 2007 R2, a CAL is required for direct or indirect access authenticated via Active Directory. This essentially requires CALs for internal users, but eliminates the need for anonymous external users, which allows external users to attend an Office Communications Server 2007 R2 Web conference without the requirement of a CAL or External Connector.
The following usage scenarios for Office Communications Server 2007 R2 require that CAL licenses be in place for each user or device:
For Office Communications Server 2007 R2 voice extensions
For internal users organising or attending a Web conference
For IM identities hosted on the Office Communications Server 2007 R2 Server
The following usage scenarios for Office Communications Server 2007 R2 will NOT require that CAL licenses be in place for each user or device:
For users receiving a call from an extension hosted on the Office Communications Server 2007 R2 Server
For Non Office Communications Server 2007 R2 users placing a call to an extension hosted on the Office Communications Server 2007 R2 Server
For public network or federated users with an Office Communications Server 2007 R2 user
For external users attending a Web conference

Public IM Connectivity (PIC) remains a separate license, unchanged from the current Office Live Communications Server 2005 offerings.
Speech Server (2007 R2) is included as a software component in both Office Communications Server 2007 R2 Standard and Enterprise server editions. Utilising the Speech Server role within Office Communications Server 2007 R2 requires the Office Communications Server 2007 R2 Enterprise CAL.
