Phone system planning is not always as simple or straight forward as you would wish. However planning can be done with some level of ease in Office 365 for a Cloud PBX solution.
Check out this Microsoft article:
Find information on Microsoft’s Phone System in Office 365 (Cloud PBX) solutions for enabling call control and Private Branch Exchange (PBX) capabilities in the Office 365 cloud.
Microsoft offers a variety of options for enabling your users to call landlines and mobile phones through the Public Switched Telephone Network (PSTN)—whether their accounts exist in Office 365 on Skype for Business Online or in your on-premises Skype for Business Server or Lync Server 2013 deployment.
This article outlines the different Microsoft voice offerings, and then provides guidance on which options might be the best for you, depending on your organization’s current status and future plans. You can use this article along with the Skype for Business Online Voice Solutions poster available as a download in both Visio and PDF formats.
Enterprise Voice is Microsoft’s world-class software-powered Voice over Internet Protocol (VoIP) solution, included in on-premises deployments of Skype for Business Server. Enterprise Voice offers a rich set of capabilities and features, including Response Groups, Call Park, Enhanced 9-1-1, and much more. Enterprise Voice is a full Private Branch Exchange (PBX) system for your organization, including PSTN connectivity through your local operator.
Phone System in Office 365 (Cloud PBX)
Phone System in Office 365 is Microsoft’s technology for enabling call control and PBX capabilities in the Office 365 cloud with Skype for Business Online. Phone System allows you to replace your existing PBX system with a set of features delivered from Office 365 and tightly integrated into the company’s cloud productivity experience.
With Phone System in Office 365, your users can use Skype for Business Online to take care of basic call control tasks, such as placing and receiving calls, transferring calls, and muting and unmuting calls. Phone System users can click a name in their address book, and Skype for Business places a call to that person. To place and receive calls, Phone System users can use their mobile devices, a headset with a laptop or PC, or one of many IP phones that work with Skype for Business. For administrators, Phone System provides the ability to manage calling within the same Tenant admin console used for messaging, collaboration, and so on.
As with traditional PBX systems and with Enterprise Voice, calls between users in your organization are handled internally within Phone System, never going to the PSTN. This applies to calls between users in your organization located in different geographical areas, removing long-distance costs on these internal calls.
To enable calls to landlines and mobile phones, Phone System can be connected to the PSTN in one of two ways:
- By purchasing Calling Plan—the PSTN calling plan add-on to Office 365.
- By using on-premises PSTN connectivity, where software on-premises connects with your existing telephony infrastructure.
