Scalable and Secure Cloud PBX Phone Systems

A private branch exchange, or PBX, is a telecom switch that typically exists on the physical premises of a business, requiring IT teams to maintain costly on-site phone system hardware. A cloud PBX is the virtual version of the PBX system, with the cloud business phone system using voice over internet protocol (VoIP) to automatically answer and route calls.

A traditional PBX is hardwired with the public switched telephone network (PSTN) to initiate a call. With virtual PBX solutions, the PSTN network uses an internet connection to route the call. Cloud PBX services are hosted in secure, remote data centers, versus physical locations.

Why switch to a cloud PBX system?

Physical, on-premises business phone systems were fine when the majority of the workforce was in the office, though they came with expensive hardware and maintenance burdens. But with the onset of the COVID-19 pandemic, employees everywhere suddenly had to operate within the confines of their own homes.

As a result, companies faced unprecedented communication challenges, with IT teams struggling to manage the mix of environments and address the lack of hardware accessibility. These challenges are only going to evolve with the future of work, as businesses prepare to support a distributed, hybrid workforce .

Today’s businesses need flexible and agile business phone systems that can keep pace as their organization evolves. Switching to a PBX cloud phone system is fundamental for enabling an everywhere workforce so employees can communicate and collaborate easily, no matter where they are.

With cloud PBX solutions, all you need is an internet connection. You can avoid large, hidden costs that come with phone system equipment and infrastructure management and enable users to make and receive calls from a device and environment of their choosing.

Despite its growing popularity, there remains a lot of confusion over VoIP phone systems and how they work. You may have heard the terms fixed VoIP or non-fixed VoIP. Both VoIP phone services use essentially the same technology, but understanding the key differences between the two is critical to choosing the right option for your business.

Advantages of Cloud PBX vs. Hosted PBX

	Hosted PBX	Cloud PBX
Cost-effectiveness	Massive on-site phone system hardware that comes with hidden maintenance costs and charges for long-distance calls.	Up-front costs are tempered by the ongoing ease of a cloud PBX. Maintenance costs are nearly nonexistent — businesses simply upgrade the desktop or mobile app when there’s a fix or update.
Ease of use	With employees often receiving one dedicated piece of hardware each, a legacy PBX system requires workers to stay at their desks to receive phone calls. If they need to move desks, they have to change phone numbers.	A virtual PBX frees users from their desk phones, giving them the ability to communicate regardless of their location or their device. With cloud PBX business phone systems, employees have the flexibility to communicate from anywhere, transfer calls to video meetings, streamline global telephony carrier management, and more.
Management	IT administrators provision users through a lengthy, manual process. They can’t roll out updates, monitor usage, or troubleshoot issues their phone systems might have.	IT teams can easily provision and manage users, as well as intelligently monitor business interactions with a centralized administration portal.
Reliability	Businesses are forced to rely on business phone hardware in their office and their local phone service provider, which can be an issue if there are equipment issues, power failure, or local outages.	As long as users have an internet connection, they can make and receive calls from a PC or mobile device. If a building has a power outage, users can still make calls from another location.
Integrations & partnerships	Traditional PBX solutions typically leave businesses stuck with one single hardware provider. Employees don’t have the ability to connect phone communications with other business applications.	Some cloud PBX providers, like Zoom Phone, integrate with leading business applications, as well as work with a select number of hardware partners. Users may also have the option to use their current phone service provider to power a cloud PBX service.
Support	Maintenance calls for expert IT technicians and service changes typically result in a lengthy request process.	A Cloud-hosted PBX service like Zoom Phone offer quality monitoring dashboards and call detail reporting, giving administrators the power to proactively monitor and troubleshoot call quality issues.
