This article will provide a walkthrough on activating Microsoft single sign-on in the multi-tenant side of the bvoip phone system.

Updated at April 25th, 2024

Required Access Notice

To enable the Microsoft Single Sign-on function, you must have one of the following roles in Microsoft 365:

  • Global Administrator
  • Privileged Role Administrator

If you do not have one of these roles, please contact your IT team for assistance.


Setting up Microsoft SSO 

Starting from the login page, bvoip enables customers to use their Microsoft 365/Entra ID tenant as their authentication provider, greatly simplifying the login process and making it so users do not need to remember a separate password or MFA code.

The steps in this article will cover setting up Microsoft SSO for all phone system users in a multi-tenant capacity. 

Azure AD is now Entra ID

Although our documentation may still mention Azure Active Directory, Microsoft has rebranded this product as Entra ID. As a result, these terms are used interchangeably throughout the knowledgebase.

Signing In with Microsoft Single Sign-on

Once activated for your users, they will use the normal login screen for accessing the phone system. However, instead of filling out the standard username and password fields, they will be able to login with a click of a button. 

  1. Click on the Sign in with Microsoft button. A pop-up will appear with the Microsoft login prompt.
  2. Sign-in with the desired Microsoft login details.

Next Steps: Bind Your New Users

New users need to be bound to an extension in one of your phone systems before they can access the Web Client and 1Stream systems. Follow the Setting User Bindings guide for more details.
