Dial-in conferencing enables anonymous users and enterprise users who want or need to use a public switched telephone network (PSTN) phone to join the audio portion of an on-premises conference. Dial-in conferencing relies on the unified communications application Conferencing Attendant to provide users with a conference access phone number and reservation-less meetings. By deploying the Conferencing Add-in for Microsoft Office Outlook, users can also schedule conferences that include Conferencing Attendant access phone numbers.
Conferencing Attendant is designed to use components and features of Enterprise Voice by default, but you can configure support for dial-in conferencing in your organization whether or not you have deployed Enterprise Voice for Office Communications Server 2007 R2.
