Hosted Versus On-Premise PBX

Complex PBX | Gradwell

Despite the huge growth in digital communication tech, most businesses still rely to one extent or another on good old fashioned telephone calls. Or to be completely accurate, on a modern, updated version of the traditional technology.

Gone are the days of an operator sitting in front of a massive switchboard, fiddling with analog switches and pins to connect calls. Most businesses these days use a PBX, or Private Branch Exchange, a series of automated multi-extension phone lines, getting rid of the need for a live operator, and largely carried out over a VoIP (Voice over Internet Protocol). This allows phone calls to be made over broadband internet, rather than a traditional landline.

The popularity and effectiveness of this tech has led to a dilemma for many businesses. Now that their telephone exchange is internet-based, does it make more sense for them to keep managing it in-house, or use a purpose-built hosted PBX system?

This question is perhaps not as straightforward as it might appear, as both options have a bunch of pros and cons, and the eventual decision will most likely depend largely on your individual business, and its specific needs.

Luckily, Gradwell can help. We’ve pulled together a short guide to the positives and negatives of hosted vs on-premise PBX, to help you decide on the best option for your business, and to demystify some of the PBX solutions. Read on to get an idea of what will work best for you.

When businesses approach the MSP market, many fall into the trap of opting for a range of suppliers to manage various services in a bid to cut down on overhead expenditure. While it may be tempting to use multiple suppliers to save money, this can slow down your setup process by causing service fragmentation.

Instead, you should look for an MSP that offers all the services you require; you should work with one MSP that can meet all your specific company needs. A good MSP will ask about your specifications early on, including your data usage, storage and remote working. They should have a good better understanding of your business and industry as they will need to understand how segments will work together.

What is hosted PBX?

Hosted PBX is where an outside provider ‘hosts’ your PBX, providing the physical servers and the services to run your phone network. This will often be a cloud hosted PBX, and the provider will also be responsible for maintaining, securing and updating the PBX.

What is on-premise PBX?

On-premise PBX keeps it all in-house, with the phone system physically deployed in your offices. The company will buy and own all the necessary equipment, and will have complete control over all aspects of the PBX, including maintenance, moves, changes and updates.

Cost

One of the big differences between on-premise and hosted PBX is about upfront costs.

Hosted PBX turns your phone system into a monthly expense, as they tend to be charged on a subscription basis, with varying plans depending on the number of users.

On-premise PBX usually comes with a lower monthly cost, but needs more money to be spent upfront. Your business will need to buy equipment and licenses to set up the system, but from then on monthly costs will be largely around maintenance and upgrades.

For larger organisations with the capital, buying your own equipment upfront is often preferable, whereas for smaller businesses and start-ups, transferring the cost of your PBX from a purchase to an expense can be really helpful.

Flexibility and control

It is important to think about the level of access and control you will want to have over your PBX, as there are significant differences between the two options.

On-premise PBX gives you full control over the system. You’ll be able to add users, make changes, fine-tune settings, and create advanced interactive voice responses to your heart’s content. You’ll also be able to integrate the PBX with your existing CRM, if necessary.

Hosted PBX is a little more hands-off. PBX providers open up enough of the system to give users control over what they need to do, but will take care of everything else. Hosted PBX also means that the provider takes care of the maintenance, which can be a huge positive for smaller companies with fewer resources.

Essentially it is a question of control vs responsibility. More control over the system equals more responsibility for maintaining and managing it. This is one of the more attractive qualities of a hosted PBX, as everything is sorted for you, allowing you to get on with your core business and work more effectively.

It is also worth thinking carefully about the future of your business, particularly in terms of staffing. If you are expecting significant growth, or spikes in the number of employees, a hosted PBX might easier to manage than an on-premise system. With a hosted PBX you pay for what you use, so if your user numbers go up (or down) it is an easy fix. With an on-premise system, you’ve paid upfront, so contractions mean wasted resources, and growth requires more investment.

Resources

As you might expect, an on-premise PBX is a bit more legwork than a hosted PBX, and it is worth considering the resources you are able to throw at the system before making your choice.

Larger companies with well-resourced IT departments might well prefer an in-house option. The IT department will need to have the skills to install and setup the system, and the time and resources to manage and maintain it.

A hosted PBX, on the other hand, is far less demanding. Smaller organisations, startups, and anyone without significant IT resources will find someone else taking care of the setup, and the day-to-day running extremely useful.

Structure

The final piece of the puzzle to consider is your own organisational structure. Is your business centralised in one location, or do you have multiple offices and a host of remote workers?

An on-premise PBX is totally capable of dealing with remote working, but it is a little more complicated, and can be more expensive or require additional equipment and setup. This is unnecessary in a hosted environment, as the PBX itself is remote, meaning no installation headaches or issues with remote users.

For fully remote organisations, the issue of physical space for equipment can also come up. If you don’t have a central office, then you are going to struggle to find somewhere to store your servers! At this point a cloud PBX is particularly appealing.

For larger organisations with great IT resources, and a centralised working structure, an on-premise PBX is a great option. However when it comes to smaller organisations, start-ups, or companies with fewer resources, the lower upfront costs and lessened maintenance responsibility of a hosted PBX can be really attractive.
