Users without access to a computer who want to join an Office Communicator audio conference can now call into the conference using a regular mobile, desk, or home phone. Previously, the only way for the organizer to include a user who only had access to a phone was to call the user from within Office Communicator.
Now, when you schedule an audio conference by using the Conferencing Add-in for Microsoft Office Outlook, you can add a conference call number to the conference. The Outlook invitation contains the dial-in information. Participants can use any phone to dial into the conference and enter the conference ID and personal identification number (PIN) when prompted. After the participant joins the audio conference, he or she appears in the conference roster.
