Comparison of On-Premise Vs Cloud-Based PBX Benefits and Costs

When choosing a phone system, businesses are often faced with one critical decision.

Select an on-premise or cloud-based phone system?

With an on-premise solution, your phone system is centrally stored at your location, and your or your IT company will need to provide the service and maintenance. A cloud-based solution uses your Internet connection to connect to the cloud, requiring no additional hardware beyond the phones. System updates are all handled directly by your VoIP provider.

Cloud-based systems are growing in popularity due to remote work environments and the benefits they provide over an on-premise system.

Let’s take a look at the benefits cloud-based PBX provides over on-premise.

On-Premise

Cloud Based

Cost


  • Can be up to 40% more costly than cloud-based, requiring cabling, hardware, closet space, electrical and cooling

  • Pay in advance for planned growth

  • If your business has multiple locations you will need multiple systems

  • Upgrades and maintenance costs can add up over time

  • No hardware costs except for the phones themselves

  • Pay only for what you need and use

  • Multiple locations are supported by one phone system
    in the cloud

  • Most features and upgrades are included in cost

Installation


  • Installation takes longer with on-premise due to significant hardware required for the set-up. More office space needed to store equipment.

  • Quick and easy setup and installation due to minimal hardware deployment.

Scalability


  • Hard to scale, requiring thorough planning and accurate forecasting of needs.

  • Takes weeks or months to add or delete phone lines.

  • Scales to your needs as you grow, using exactly what you need when you need it.

  • Phone lines can be added or deleted quickly. In days in most cases.

Maintenance


  • Requires an IT Specialist to manage and make changes.

  • Other than phones, no maintenance is required.

Upgrading Features


  • Time to market varies

  • Upgrades requires manual updates from an IT specialist or the hardware vendor

  • Technology is always evolving and with cloud-hosted time to market is immediate.

  • All upgrades are made available automatically through the cloud

Mobility


  • Mobile compatibility is complex and expensive

  • Anyone can connect from multiple devices

Disaster Recovery


  • Redundancy is possible, but costly

  • Recovery is typically slower, negatively impacting
    customer experience

  • Geo-redundancy, while possible, requires double
    the space, hardware, software, and capital

  • Built-in fail-over in the event of Internet or power loss

  • Calls automatically rerouted to other data centers
    so customer experience is not affected

  • Geo-redundancy is built in, with no need for a
    capital outlay for space, hardware, or software
