5 myths of switching from on-premises PBX to cloud

Table of Contents

Work in a post-pandemic world will change in unprecedented ways. Several major companies have already begun to adopt permanent work-from-anywhere models. And many are looking at hybrid approaches—where employees split their time between the office and home.

So how do companies support the new norm? For starters, a fundamental shift in technology might be in order. During the COVID-19 lockdowns, businesses discovered that their on-premises systems couldn’t support an increasingly remote workforce. Many of them turned to digital transformation and the cloud instead.

Despite the shift, though, many leaders still might be on the fence. They might have concerns about security, costs, and other factors. But in the post-pandemic workplace, switching to the cloud isn’t just a luxury—it’s become a must.

That being said, let’s address some of the top myths behind switching from on-premises PBX to the cloud.

Myth #1: On-premises solutions are more stable than cloud solutions


You might think maintaining connectivity and service is easier when your infrastructure is located in the same building as you. After all, you can easily access your system for troubleshooting and repairs.

However, with on-premises systems, you’re entirely at the mercy of whatever is happening locally—meaning a power outage or weather event can knock out service entirely. At the same time, you won’t know there’s a problem with your system or equipment until the lines go down. 


Cloud solutions are housed in multiple geographically distributed data centers. If one location is affected—whether by an unexpected event or even high levels of usage—traffic is routed through another data center, with no service interruptions to your users.

The best providers proactively monitor their networks 24/7 so they can detect, diagnose and address issues as quickly as possible, often preventing service disruptions before they happen. 

Furthermore, most enterprise cloud communications providers stand behind their obligation to provide reliable service via a Service Level Agreement (SLA) that guarantees a minimum percentage of uptime, or maximum downtime. To ensure maximum service with the fewest interruptions, look for a provider that guarantees the “five 9s”—or 99.999% uptime. – Read more
