The Office 365 version of Microsoft Lync does NOT include the ability to place calls to or receive calls from the PSTN, the functionality that Microsoft refers to as “Enterprise Voice.” Enter AudioCodes One Box 365. One Box provides an on-premises appliance that allows you to use part of Office 365 along with a version of Lync that provides full Enterprise Voice capabilities. This allows you to keep the simplicity and productivity of using Microsoft software in the cloud without the cloud-based Office 365 limitations.
