Cloud PBX

Works seamlessly with Office 365

Operate your business phone system in the cloud and eliminate the need for traditional PBX hardware and the associated maintenance costs. And because Cloud PBX in Skype for Business works with Office 365, your system is always up to date with state-of-the art features.

Works for all your conversations

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.

Scales globally

Connect your phone system to the Microsoft worldwide network—and get the power of the Microsoft cloud wherever your business goes. You can even use your own operator connectivity to call landlines and mobile phones using simple on-premises software.

Cloud PBX includes:

What is Cloud PBX?

Cloud PBX enables you to make, receive, and transfer calls to and from phones, mobile phones, tablets, and PCs, from nearly anywhere that has Internet access. With Cloud PBX, you don’t need a separate phone system because users get all the calling features they need, and IT administrators can use the Office 365 administrator portal to manage users’ communications.

Can I use Cloud PBX with my existing telephony provider?

With Cloud PBX, you can connect your existing PSTN service provider with Office 365 allowing calls coming through your existing on-premises infrastructure to connect with Cloud PBX. If you already have Skype for Business Server deployed on-premises, you can use that software to connect between Office 365 and your existing PSTN circuits. New customers can deploy the Cloud Connector Edition of Skype for Business Server, which provides a more streamlined deployment approach using pre-packaged Virtual Machines to connect to your PBX, SBC, or Gateway.

What are my options for using Cloud PBX for calling?

While Cloud PBX provides the call control capabilities for end users and the administrative features for IT, it connects to the PSTN through either Microsoft PSTN Calling add-on or to your existing PSTN circuits using Cloud Connectivity.

Are there any prerequisites that I need to purchase and provision before I can use Cloud PBX, PSTN Conferencing, or PSTN Calling?

Yes, in order to use these services, you must have Skype for Business Plan 2, or equivalent E SKU (E1/E3/E5), deployed as a standalone or as a component of Office 365 Enterprise E1, E3, or E5 suites. To use PSTN Calling, you must also purchase Cloud PBX or Enterprise E5 (which includes Cloud PBX functionality) as a prerequisite. To use the full Cloud PBX capabilities, including voice mail, you need Exchange Online Plan 2 and the Skype for Business Client.

Can I use Cloud PBX to connect to my on-premises telephone provider?

If you are an Office 365 Enterprise E5 or Cloud PBX customer, you can connect your existing PSTN service provider with Microsoft cloud-based call control. Scenarios are based on whether a customer already has a Skype for Business Server deployed. You can set up a new server pool or use an existing Skype for Business Server deployment to configure it to connect to Cloud PBX functionality that is covered under existing server licensing.

If you don’t have an existing server, you can use a minimal Skype for Business Server deployment through the Cloud Connected Edition that includes four preconfigured Virtual Machines (VMs) deployed on customer-owned Windows Servers. Skype for Business Server roles in VMs are not paid roles and are licensed for use with Cloud PBX.
