I’ll be one of the first to tell you that shopping for a Unified Communications solution for your business is no easy task. With the sheer amount of jargon and technical terms that accompany UC, it can be difficult to even wrap your head around what you’re looking at or reading about. Add on top of that the vast number of options between different vendors, providers, partners, hardware manufacturers, and you need a map just to navigate this field of business VoIP.

And just to make everything even more confusing, before you begin searching for a VoIP provider, your business must decide how exactly to establish and host a communications platform. Of course, we’re big advocates for cloud-based or hosted solutions, with a growing list of reasons to switch your business over.

However, adopting an entirely hosted solution isn’t always the best option for everyone — sometimes an on-premise solution or hybrid cloud works best.


What is On-Premise vs cloud?


Well, before you can even begin comparing different platforms and providers, your business must understand the different delivery methods, and the implications behind each. Depending on several factors from the business size, to location, to specific team needs well help determine how large or small the investment must be.

For example, cloud vs on premise solutions can help save costs upfront, but reoccurring monthly charges will only grow as your business grows — so a 10,000 seat Enterprise might want to consider a standard On-Premises approach. However, on-premises solutions can make mobility difficult in an increasingly mobile world.

But before we bog you down with a list of generalities, lets clearly define the options and what they mean for your business:



Pretty much just as the name states, on-premise solutions are in-house telephony and communications platforms, mainly used by the largest organizations. Instead of subscribing to another service, the business will pay for their own IT infrastructure and work closely with a provider to build an entire communication system for the entire business. On-premise solutions could be based off a Standard PBX, SIP Trunking, or more recently might include IP PBX and VoIP capabilities if building out a hybrid solution.



Generally, when you think Business VoIP, you are thinking of a hosted solution. With a cloud solution, all the heavy lifting is handled by the service provider — your business may need to purchase some phones, routers or network switches, but other than that turning on the service is essentially a flip of a switch. The provider hosts the network and service in their data centers around the world, and provides access to your business with a reoccurring subscription fee.



Kind of like the best of both worlds, a hybrid solution allows a business maintain control over their platform in-house, but also offer the service through the cloud, all around the world. So, just like in an on-premise solution, your business acquires the necessary hardware to establish and maintain their own telephony and communications platform. But, just like a hosted solution, your business can then disperse this platform to all other locations, through the cloud — remote locations in other cities can receive the same service without having to subscribe to another provider, or build their own infrastructure.


What Are the Key Differences?


So of course, simply defining the solutions does not tell the whole story. There isn’t a “best” or even “better” option, but rather whatever works best for each particular use case. A one-size-fits-all approach would just be too broad and generic, falling short of the unique needs each business will have. Cloud computing must be accompanied with training on how to protect sensitive data adn how it integrates with your current operating systems, so this can increase the toal cost.

Depending on a lot of different factors, like the size of your business, the number of locations, the number of teams, capital to spend, and more, your organization will have to come to an independent conclusion on what the right solution might be. And to help you understand that, we can break down each solution and their specific benefits:


Benefits of On-Premise Software

  • Enhanced control over the entire system. With all the hardware related to your network located in-house, your business gains complete and total control. Your business will generally need to retain IT professionals for setting up and maintaining the network with the ability to control every single aspect. This enhanced control allows for enhanced security as well — since everything is in-house the entire network can be protected by physical firewalls with IT staff acting as the guards.
  • Potential Cost Savings by avoiding reoccurring costs from a subscription. When establishing an on-premise solution, your business might require a single one-time purchase of hardware and services, which will allow your organization to depreciate the costs over time. With a hosted solution, your business is always paying monthly, and the costs will only grow as you add more phone lines and features, when your company grows.
  • Stronger Integrations that don’t already exist could be built with in-house IT teams and professionals hired to maintain the solutions — as opposed to relying on a cloud provider to offer an API, or built their integrations. CRM integrations are popular, but it can be difficult to come across UC integrations with accounting software, for example
  • Regulation and Continuity Requirements might require organizations within different industries to install and maintain their own communications solutions. Because of the enhanced control, your business can gain enhanced compliance and ensure the network and business is adhering to different regulations. Going even further, an in-house solution can help ensure continuity and disaster recovery. If a disaster strikes and hosted services go out, you better hope the provider can get it running quickly. But on the other hand, if your business’s on-premise network goes down, your business can act quickly and fix it, or reroute communications to other servers.


Benefits of Hybrid Unified Communications

  • An easy transition to a cloud-only service can be made possible with a hybrid approach. By integrating both a cloud and an on-premises solution into one, a hybrid approach can allow a business to utilize existing PBX infrastructure and hardware to deliver UC functionality over the cloud. This approach can help a business transition to a new cloud approach without jumping ship all at once, and avoid some of the more common mistakes.
  • Disperse your Service to different locations through a hybrid approach. With physical hardware located within the organization’s mean location, remote offices can be fed service through a cloud delivery model. Essentially, your business will be offering its own in-house communications services as a hosted solution, but only to your organization’s other locations.
  • Go Cloud, Yet Save Costs at the same time by utilizing existing on-premises software to disperse the service. Your business won’t have to pay for any other hardware, or a recurring subscription to access the platform. With control over the system in the main location, your business can also gain some financial flexibility, with the ability to specifically decide what features to stay on-premise and which can be hosted in a public cloud or private cloud.
  • Stay On top of Security with a hybrid approach by maintaining control over the network. Since the hosted service is still running off of your organization’s hardware, located on-premise in one main location, the business can maintain control over the network, and therefore the network’s security. On-premises equipment can easily be protected with hardware firewalls or even other tools like in-house encryption, and session border controllers.


Benefits of a Cloud Environment

  • A subscription model for your phone system eliminates the need for a large capital investment, as startup costs are usually less intense and the service is paid for overtime. This eliminates the need for in-house IT and staff to maintain the service, only further saving costs for the business. For small teams, why pay extra for what you don’t need, like the expensive hardware for an on-premise solution?
  • Get Going Quick and Easy with off-site hosted solutions. Establishing an entire communications platform with a hosted solution can happen in a matter of days, or at most weeks. However, building an entire on-premise network can take months, since Cloud solutions don’t necessarily need an IT department to get it all going. With UC as a Service, the setup is handled by the provider, and all your business needs to do is log in to the online admin portal.
  • Simple to Maintain is the motto of cloud services. There’s no costly hardware, no physical connection to the PSTN, no tricky server room that requires trained IT professionals. If your business needs to change a feature or add new lines, that can all be handled through simple online portals. Again, the “heavy lifting” so to speak, is handled by the provider.
  • Increased Flexibility generally goes hand-in-hand with a cloud platform. Since the service doesn’t require an expensive hardware installation process to add on new phone lines or even new features, your business can manipulate the platform in a matter of seconds. However, this increased flexibility can bring along with it an increased cost — adding a new phone line is as simple as logging into your account, but users generally pay for the number of lines on their account, driving the cost up as the business grows. On top of that, a cloud infrastructure allows for more SaaS integrations and improved data security.


Unified Communications Must Meet Customer Needs


While the options seem endless, at the end of the day the right choice depends on exactly what your business needs. There is no one right answer, and there is no one-size-fits-all approach. Each business also has its own unique needs, unique locations, and unique industry requirements.

Consider both your own needs and customer needs including security concerns, downtime, upfront investment on server hardware , and how cost-effective your system is. Those upfront costs will trickle down to customers so consider how IaaS could offer complete control over capital expenses.

With an understanding of what options even exist out there, your business can then narrow down into different areas of focus. The first step would be simple to understand what options exist, and why they exist. The best way to make a decision is to be informed on the decision, but also informed on what your business needs, and doesn’t need.
