Office Communications Server 2007 R2 Product Overview – v 2009.1.30 29
On-premises audio conferencing
Save conferencing costs by setting up an on-premises audio conferencing bridge for internal and
external users and by replacing external services that offer reservationless audio solutions. The on-
premises audio conferencing bridge that supports both VoIP connections and PSTN dial-in audio
participants is new in Office Communications Server 2007 R2.
One-click setup from Office Outlook 2007
With a single click, users can schedule a conference call from Office Outlook (see Figure 23). Details,
such as meeting time, location, and attendees, follow the familiar Office Outlook template. Additionally,
conference call-specific information, such as dial-in number, meeting IDs, and PIN reminders, are
automatically populated.

Multiple levels of authentication for more secure conferencing
To help ensure that only the authorized people participate in a call, Office Communications Server 2007
R2 provides several call setup options:
Open Authenticated: Only participants who are authenticated against Active Directory can join
the call.
Closed Authenticated: Only participants who are authenticated against Active Directory and are
on the list of conference call attendees can join the call.
Anonymous: Anyone with the proper meeting ID and participant passcode can join the call.
Corporate enterprise voice users validated against Active Directory
Users who join via Office Communicator and Office Communicator Phone Edition are already
authenticated against Active Directory. There is no need to enter a PIN or pass code. For users joining
via Office Communicator, there is no need to input the meeting ID either. Users truly experience a
much more simplified “click to join” experience.
Unified conferencing means more than just audio is available
Unified conferencing provides a seamless escalation process between audio conferencing and other
communications modalities, such as desktop sharing and video conferencing.
Better control of an audio conference
Office Communications Server 2007 R2 improves the user experience by providing the Office
Communicator interface for call management as opposed to asking users to memorize Dual Tone
Multi Frequency (DTMF) codes for functions such as muting their phone.
