What Is Hosted PBX (Private Branch Exchange)? A Guide – Voip Elements

Hosted PBX, a private branch exchange (PBX), is a telecommunications system managed and operated by a service provider. Unlike traditional PBX systems, which rely on copper wires and landline phones, hosted PBX utilizes the internet for making and receiving phone calls.

Businesses opt for hosted PBX, or transition from traditional PBX setups, for various reasons. Cost efficiency, access to advanced telecommunications features, and the desire to streamline workforce communication are among the primary motivations.

For businesses exploring telecommunications solutions, hosted PBX presents a compelling option. This guide covers everything you need to know about hosted PBX systems, including their functionality, benefits, and reasons why they may be the right choice for your business.


Understanding Hosted PBX

Understanding Hosted PBX

Being kept online and separate from the physical location of the business, a hosted PBX—basically, a cloud-based phone system—requires less maintenance and saves money.

The word “private branch exchange,” or “PBX,” refers to the system that allows calls to be transferred between lines inside of a company. Telephone operators handled and switched lines by hand to route calls to the appropriate people when the industry first began with analog PBXs.

The name IP PBX comes from the fact that the function is now online. Furthermore, cloud PBX, virtual PBX, and hosted IP PBX are terms that are commonly used to describe cloud-based PBX.

Not having to pay for maintenance, software, hardware, or training. With little installation costs, a hosted private branch exchange phone system is completely managed off-site.

Because of these advantages, more businesses are selecting cloud PBX service providers as their economical and practical office phone service provider. We will discuss additional benefits of cloud-based PBX services later in this article. 


Traditional PBX vs hosted PBX

Traditional PBX vs hosted PBX

On-premises PBX and analog PBX are other names for traditional PBX systems. These PBX systems are operated by on-site software that is placed at your company’s office, together with physical hardware like copper telephone wires.

Your on-site PBX establishes a connection between your landline and the Public Switched Telephone Network (PSTN) when you place a call. The Plain Old Telephone Service (POTS) is another name for that system.

Hosted PBX uses VoIP technology to transmit voice traffic over the internet. Instead of using standard desk phones with separate extensions, businesses that use hosted PBX for their communication systems typically employ VoIP phones, also known as IP phones or softphones.

Instead of using copper cables and the PSTN, the hosted PBX infrastructure is fully maintained by the service provider and is connected to the internet.


Here are some of the key differences between on-premises traditional PBX and hosted PBX:


Traditional PBX Hosted PBX
On-premises hardware and software Infrastructure managed by provider via internet
Relies on copper wires and PSTN (POTS) Relies on internet connectivity
High initial set-up costs Minimal set-up costs
Requires on-site IT staff Provider handles maintenance
Expensive to scale Easy scalability
More control over PBX system Hand over control to service provider
Basic calling features Additional features like IVR and ACD included

This comparison clearly outlines the distinctions between traditional PBX and hosted PBX systems, highlighting their respective characteristics and advantages.


How Does Hosted PBX Work?

How Does Hosted PBX Work?

Hosted PBX (Private Branch Exchange) operates on the principle of utilizing internet protocol (IP) for communication, enabling organizations to manage their phone systems virtually through a service provider. Unlike traditional PBX systems that rely on physical hardware and copper wires, hosted PBX leverages the internet to transmit voice data, offering a more flexible and cost-effective solution for modern businesses.

At its core, hosted PBX works by routing calls over the internet rather than traditional phone lines. When a call is initiated, it travels through the organization’s internet connection to the service provider’s data center, where the call processing occurs. This data center houses the necessary hardware and software infrastructure to manage the entire PBX system efficiently.

Here’s a Breakdown of How Hosted PBX Operates:

  1. Initiating a Call: When a user dials a phone number, the signal is converted into digital data packets and transmitted over the internet to the hosted PBX provider’s data center.
  1. Call Processing: At the data center, the call is received and processed by the hosted PBX software. This software manages various call features, such as call routing, voicemail, call forwarding, and call recording.
  1. Routing the Call: Based on predefined rules or configurations set by the organization, the hosted PBX system routes the call to the intended recipient. This can include routing calls to specific extensions, departments, or even external numbers.
  1. VoIP Technology: Hosted PBX systems often utilize Voice over Internet Protocol (VoIP) technology to transmit voice data efficiently over the Internet. VoIP converts analog voice signals into digital data packets, ensuring clear and reliable voice communication.
  1. Accessibility: Hosted PBX systems offer accessibility from anywhere with an internet connection. Employees can make and receive calls using desk phones, softphones (software-based phones), or mobile apps, providing flexibility for remote and mobile workers.


Benefits of a hosted PBX phone system

Benefits of a hosted PBX phone system

Hosted PBX is replacing traditional on-premises PBX in an increasing number of enterprises.


Here are the main advantages of hosted PBX that motivate companies to switch and startups to choose a hosted PBX solution over a traditional PBX for their telecoms right away, from cost savings to enhanced flexibility:


  1. Cost Savings: Because there is no need to invest in costly hardware or infrastructure, hosted PBX systems usually have lower upfront costs than traditional PBX systems. Since the service provider handles upkeep and improvements, businesses can also save money on these expenses.
  2. Scalability: Businesses may simply add or remove phone lines and functions as needed with hosted PBX systems because of their excellent scalability. They are perfect for companies of all sizes, from little startups to huge conglomerates, due to their scalability.


  1. Flexibility and Mobility: With a hosted PBX system, employees can make and receive calls from anywhere with an internet connection. This flexibility is especially beneficial for remote or mobile workers who need to stay connected while on the go. Additionally, features like call forwarding and find me/follow me ensure that calls are never missed, regardless of the employee’s location.
  2. Advanced Features: Hosted PBX systems offer a wide range of advanced features that can improve productivity and enhance communication within the organization. These features may include auto-attendants, voicemail-to-email transcription, call recording, conferencing, and integration with other business applications such as CRM systems.
  3. Reliability and Redundancy: Hosted PBX systems are typically hosted in secure data centers with redundant infrastructure, ensuring high availability and reliability. This means businesses can rely on the service to maintain uninterrupted communication even in the event of a power outage or natural disaster.
  4. Easy Management and Maintenance: Since the PBX system is hosted in the cloud, the service provider is responsible for managing and maintaining the infrastructure. This frees up IT resources within the organization and allows them to focus on other strategic initiatives rather than managing a complex phone system.
  5. Professional Image: A hosted PBX system can help businesses project a professional image to customers and clients. Features like virtual receptionists and customized greetings can give the impression of a larger, more established organization, even for small businesses.

Overall, a hosted PBX phone system offers cost-effective, flexible, and feature-rich communication solutions that can help businesses improve efficiency, productivity, and customer satisfaction.
