Microsoft Phone System (formerly Microsoft Skype for Business Cloud PBX) enables businesses to replace their traditional phone systems by adding a set of calling features delivered in Office 365 with Skype for Business Online. With Microsoft Phone System, users can make and receive business calls in the office, at home, or on the road, using a phone, PC, or mobile device. Phone System is included in the Office 365 Enterprise E5 package, and is available as an add-on to Enterprise E3 and Enterprise E1. Businesses without Office 365 can add Phone System to a subscription of Skype for Business Online Plan 2.
Operate your business phone system in the cloud and eliminate the need for traditional PBX hardware and the associated maintenance costs. And because Phone System in Skype for Business works with Office 365, your system is always up to date with state-of-the art features. Easily transition from your old system to Skype for Business with advanced voice features. Answer, transfer, hold, and resume calls with just a touch. And instantly transform basic calls into productive, collaborative sessions with text, video, and desktop sharing.
