Unified Communications

Enterprise Skype for Business (Unified Communications)

SKYPE FOR BUSINESS (Skype4B) is a Unified Communications (UC) service that connects people everywhere - on Windows as well as other operating systems and platforms, including most mobile devices, as part of their everyday productivity experience. It provides a consistent, single-client experience for Presence, Instant Messaging, User-to-User Voice and Video, as well as a great meeting experience. Skype for Business also delivers seamless and secure integration with other Microsoft collaboration products such as Outlook, SharePoint and Office applications.

There will be three Skype for Business offerings available to the Agencies:

  • AT&T Hosted Skype For Business Basic Profile (VoIP only)
  • AT&T Hosted Skype For Business Enhanced Profile (Full UC with VoIP)
  • Skype for Business Online Provided by Microsoft on the Office 365 platform (Full UC with no VoIP)


Both of the AT&T Hosted service options include Enterprise Voice (VoIP) capabilities that will be the replacement for our current Enterprise Centrex Telephony service. The Agencies can choose which option they would like each of their users set up on, but if the user requires Telephony services with Skype4B, they must be set up on one of the AT&T Hosted Skype4B service options. The AT&T Hosted Skype4B Enhanced Profile service also includes the ability to set up Skype4B Meetings with Dial-in access numbers.
