For decades, businesses relied on traditional PBX (Private Branch Exchange) systems for communication. However, as businesses grew and technology advanced, the limitations of traditional PBX systems became apparent. They required lots of physical wires and equipment. Moreover, it was expensive and hard to change or move from one location to the other.

 

The need for a more cost-efficient and adaptable phone system led to the evolution of the Hosted PBX system. It replaced traditional phone systems requiring bulky hardware and offers a virtual communication solution for businesses.


What is Hosted PBX?

Hosted PBX is a Private Branch Exchange phone system that operates over the Internet. It’s a virtual PBX phone system completely hosted in the cloud and not tied to any physical location. It allows you to make phone calls online instead of using wired cables. Your telecommunication service provider handles and maintains all the technologies that power your hosted PBX system. 

How Does a Hosted PBX System Work?

A Hosted PBX system involves a few key components: a VoIP (Voice over Internet Protocol), stable internet, and a service provider.

 

Firstly, the system starts with a connection to your Hosted PBX provider.  When you set up this particular phone system, you’ll also install the VoIP devices designed to handle voice data over the internet.

 

As you make a call using a VoIP-enabled device, it immediately converts your voice into digital packets. Once the voice is converted into these digital packets, your phone system routes the call to your service provider’s server. Here, it transforms the digital packet back to the original audio format. Once converted, the call is sent to the intended recipient. Though this process seems intricate, it happens swiftly and seamlessly to provide a smooth calling experience.

Limitation of Hosted PBX

Despite such impressive perks and features, it isn’t without drawbacks. The Hosted PBX’s primary limitations are the complete reliance on the internet connections and concerns about the system control.

1. Dependency on Internet Connectivity

A hosted PBX system relies entirely on an internet connection, which can sometimes be problematic. When your internet service is down or unstable, it can affect your business phone system capability. It often leads to poor call quality and even dropped calls.

2. Limited Control Over System Updates

As the service provider manages the entire system, you have limited control over the updates and upgrades. You must wait for the upgrade when you require the new functionalities. Also, the upgrade might not always align with your business’s preferences. Moreover, some hosted PBX providers might also charge extra for the new features.
