What is a Cloud PBX System?

Cloud PBX systems are hosted on the internet and automatically route calls to the appropriate department or extension according to the caller's preference.

As with any new innovative enterprise technology, the VoIP industrial domain has its fair share of technology and technical jargon. If you are interested in enterprise VoIP systems you would have surely come across the term cloud PBX system and wondered what it means. The phrase also sounds quite similar to a hosted PBX phone system or virtual PBX phone system. Broadly speaking, all these terms refer to the exact same type of service-  phone service with PBX functionality which is delivered online through dedicated or shared data connections.

Let’s make the process of understanding the phrase easier by breaking down “cloud” & “PBX”.

Cloud is an umbrella term for the software & services that run on the internet. Pretty much everything these days runs “in the cloud”.

PBX is an abbreviation for Private Branch Exchange, which refers to a private telephone system that allows an organization to communicate internally as well as externally. It is the system that routes incoming calls, enables you to transfer calls to other extensions, provides business-hour settings to route off-hour calls, customer waiting queues, and hold music.

According to Techopedia, a Cloud (or Hosted) Private Branch Exchange (PBX) is "a telephone exchange system built, delivered and managed by a third-party service provider. Hosted PBX is an IP-based telephony solution provisioned and accessed entirely through the Internet."

Simply put, Cloud PBX is a virtual phone system that provides a secure and reliable business phone system through the internet. It is an IP-based PBX solution provided and accessed completely through the internet. Instead of hosting software on a server, the way digital systems do, cloud PBX hosts all software and data in the cloud.

So basically, companies can rent the virtual PBX system which is hosted and maintained by a 3rd party over the internet.

How Does Cloud PBX Work?

As with all cloud-based technologies, virtual PBX phone systems are dependent on the internet. They are flexible & portable cloud-based telephone systems that enable individuals to receive calls from almost anywhere! They allow businesses to make calls over the internet rather than using old-fashioned phone lines.

The difference lies in the fact that unlike traditional PBX systems that require on-premises hardware, the Virtual PBX system is hosted securely in the server of your VoIP provider. Maintenance and software updates are all managed externally leaving you to focus on your business. Delivered entirely over the internet and managed completely off-site, the deployment and set up is quick and easy, freeing companies from the burden of IT overheads. You can purchase the on-premise PBX system from a service provider and pay on a subscription basis. The following diagram is a simplified representation of how a cloud PBX phone system works:

Which are the Top 3 Problems Encountered When Implementing Cloud-Hosted PBX?

problems in implementing cloud pbx software

1. Insufficient bandwidth:

Before implementing a cloud-based telephone system, one needs to ensure that whether your existing network can handle the extra bandwidth required to run the chosen system.

2. Improperly trained staff:

Change is never easy and even though hosted service providers are responsible for the upkeep & maintenance of the system, there will still be a learning curve associated with implementation and the time required for everyday users to get comfortable with the most of your cloud-hosted services.

3. Ensuring security:

Hacking, toll fraud (criminals hijacking your phone system to place thousands of calls at your business’ expense) & phishing attacks are serious issues that can be countered with the most effective tool, education. Businesses also can rely on monitoring from their managed service provider to alert them if anything suspicious is taking place over your PBX (such as flagging atypical calling activity).

Troubleshooting PBX Phone Systems in 5 Steps

1. Check all device connections:

Ensure that your devices are connected to a power supply and the network. Check if all of your hardware, including phones, routers, and adapters, are plugged in correctly, including the power cords and network/telephone cords.

2. Reset your PBX and your hardware:

Reset your PBX hardware by unplugging the main cord for a minute. Reset your equipment (phones and routers) as well by unplugging all power cords for 10 seconds. Once you plug everything back in, wait for all the lights to turn back on. This will clear any fundamental issues that may have caused poor call quality. If any of your devices haven’t powered back up, flag it for repair or replacement.

3. Run a bandwidth speed test:

With a speed test, you’ll learn if your network is compatible with VoIP. Inadequate bandwidth and other connectivity issues limit the number of VoIP phones you can have. There may also be an issue with data packet transmission.

4. Confirm your router has prioritized VoIP traffic:

Ensure that your router is able to prioritize VoIP traffic and your network configuration should be set up in the right way to enable it.

5. Use the logs in your PBX:

Log into your PBX dashboard to view any errors that may have happened with your PBX. Look for a section that shows you a log of events & messages about your PBX.
