3.6 Online Sign-in through Microsoft's Cloud PBX
The phone features online sign-in and connectivity to Office 365 server on Microsoft's cloud.
Users can sign in to/connect to and authenticate with Microsoft's Cloud PBX, Microsoft's cloud-
hosted version of enterprise voice. Two sign-in method options allow users to connect to
Microsoft's Cloud PBX:
ADAL (Azure AD Authentication Library), based on OAuth 2.0 (RFC 6749).
OrgID (Organizational ID) or LiveID, Microsoft's proprietary connectivity to Cloud services.
Note: Online sign-in to the phone must be in the following format:
• Sign-in address
• Username in UPN (User Principal Name) format. UPN format is the way the user's name
appears in their e-mail address listed in the Active Directory, i.e.,
username@domain.com
• User’s network IT password
Signing in with a username that is a NetBIOS Domain Name, i.e., domain\username, as well
as signing in with the phone Extension and PIN Code, are disallowed for Skype for Business
online sign-in. They are only allowed for on-premises sign-in.
