Microsoft 365 Business Voice is a cloud-based phone system designed for small and medium-sized businesses. It integrates into Office 365 for an all-in-one communication solution that brings together calling, meetings, and messaging in Microsoft Teams. Microsoft 365 Business Voice enables businesses to simplify communications by unifying calling, chat, and meetings in Teams. It enables calling from anywhere, and allows users to connect faster, wherever they are, on any device.
With Business Voice, organizations can save time and money, and reduce complexity by consolidating all communications apps with a single provider. Business Voice enables users to start a call, schedule and join meetings more easily, right from Outlook. Meeting attendees can join just as fast from Outlook or any web browser without application downloads or sign-in required. Business Voice includes Microsoft Calling Plan, a domestic calling plan that connects the business to the Public Switched Telephone Network (PSTN) to enable calls to landlines and mobile phones around the world. With Calling Plan, Microsoft is your PSTN carrier.
