4. Planning Your Skype for
Business Voice Solution

5. Real Microsoft expertise. Real business value.™
All-in-the-cloud, on-premises, or hybrid?
• Do you want (or are required) to retain functionality provided by your
on-premises deployment?
• Do you need features that are currently available only with your on-
premises voice solution?
• How do you best provide Private Branch Exchange (PBX)
functionality, access to the Public Switched Telephone Network
(PSTN)?
• Do you need to provide conferencing capabilities for all users in your
organization?
• What your plan is for moving people to the cloud?
All of these depend on your company’s current and future needs!

6. Real Microsoft expertise. Real business value.™
What is the best solution?
The first steps on deciding what solution will provide the “best fit” can be made easier by
answering a few simple questions:
• Do I have an existing on-premises Skype for Business Server deployment?
• Are my users today “homed” in Skype for Business on-premises, in the cloud on Skype for
Business Online, or both?
• Do I want to move my on-premises users to the cloud?
• Is Microsoft’s PSTN Calling service available in my region?
• Do I want to keep my current telephony carrier?
• Do I need to keep my current telephony carrier because of an existing contract?
• Do I have an existing on-premises legacy PBX that I want or need to keep?
• Does my current legacy PBX offer unique features that are critical to my business?
• Do any / all of my users require features not currently offered in Cloud PBX?

7. Real Microsoft expertise. Real business value.™
Where do IT responsibilities sit?
Whether you consider on-premises only, cloud-only, or a mixture of
both through a hybrid deployment of Skype for Business (all of which
we will cover in this series), there are five core responsibilities that
you as the organization’s IT will take ownership for:
1. Networking and connectivity – Ensure network capacity and
availability through firewalls, proxy servers, gateways, and across
WAN links by performing a network assessment (or by contracting
with a partner to do the assessment).

2. Data governance & rights management – Classify your sensitive
data and ensure it is protected and monitored wherever it is
stored and while it is in transit.

and assets.

Where do SHARED
responsibilities sit?
• With a Cloud solution,
wither full or hybrid,
understanding where
exclusive and shared
ownership falls goes hand
in hand with understanding
the responsibilities that IT
must undertake in
managing and maintaining
a voice solution

13. On-Premises Enterprise Voice

hardware and software that are not supported by Skype for Business
Online. For example, Survivable Branch Appliance (SBA)
configurations.
• Privacy restrictions that prevent synchronization of Windows Active
Directory accounts with Office 365.
• You desire control of the entire platform and solution.

20. Cloud PBX with PSTN Calling
Comparing Skype for Business Solutions

21. Real Microsoft expertise. Real business value.™
Cloud PBX with PSTN Calling
Microsoft-hosted Cloud PBX functionality with an added PSTN Calling service enables
calling to landlines and mobile phones around the world. Because the PSTN Calling service
operates out of Office 365, this is a completely-in-the-cloud offering that does not require
an on-premises server deployment.
The Cloud PBX footprint is very simple:
PSTN
Office 365 including Skype for Business Online
Microsoft
Cloud PBX
Skype for Business
Users

22. Real Microsoft expertise. Real business value.™
Cloud PBX with PSTN Calling
Microsoft-hosted Cloud PBX functionality with an added PSTN Calling service enables
calling to landlines and mobile phones around the world. Because the PSTN Calling service
operates out of Office 365, this is a completely-in-the-cloud offering that does not require
an on-premises server deployment.
You can use the following decision tree for Cloud PBX with PSTN Calling:

calling to landlines and mobile phones around the world. Because the PSTN Calling service
operates out of Office 365, this is a completely-in-the-cloud offering that does not require
an on-premises server deployment.
Cloud PBX with PSTN Calling is great when:
• Your PBX does not offer unique features that you need to retain.
• You don’t want to maintain an on-premises PBX solution
• You don’t want to maintain any Skype for Business infrastructure.
• You want to use Microsoft-provided PSTN services (and PSTN Calling service is available
in your region).
• You want to leverage Office 365 for your subscription-based licensing.
• You want to use cloud-only features like Skype Meeting Broadcast & PSTN Conferencing

24. Real Microsoft expertise. Real business value.™
Cloud PBX with PSTN Calling
With Office 365 integration you have the following advantages:
On premises
Office 365
Exchange Online
SharePoint Online
Skype for
Business Online
• Use Skype for Business Online for Cloud PBX, off-
loading the burden of on-premises PBX systems.
• Use Exchange Online for email, off-loading the
burden of on-premises email servers and storage.
• Use SharePoint Online for collaboration, off-loading
the burden of maintaining on-premises SharePoint
servers.
• Use Skype for Business, Exchange, and SharePoint
integrated features, including Unified Messaging
(UM) in Office 365.

25. Hybrid Voice
Comparing Skype for Business Solutions

26. Real Microsoft expertise. Real business value.™
Hybrid Voice
If you have an existing Skype for Business Server deployment, you can
choose a hybrid offering that consists of a Skype for Business Server on-
premises deployment modified for hybrid PSTN.
Users in your organization who are homed in the cloud can receive PBX
services from the Microsoft cloud, but PSTN connectivity is provided
through Enterprise Voice on your on-premises Skype for Business Server
deployment.
Plus you can use cloud-only features like Skype Meeting Broadcast & PSTN
Conferencing

27. Real Microsoft expertise. Real business value.™
Hybrid Voice
This deployment can be the most complex, as it requires components from
both an on-premises as well as the cloud - based on where users are
“homed”.
