Different Types of PBX System

February 4, 2023


As with any other equipment, businesses must ensure that the PBX they end up implementing meets all requirements. There are many types of business PBX should consider adopting, but not all types actually meet the needs.

What is a PBX?

This is a business phone system that allows businesses to transfer calls between users on local lines as well as access external phone lines. Some of the benefits of a PBX include:

  • Cost reduction
  • Flexibility in service plans
  • Expansion
  • Capital expenditure
  • Professional image
  • Reliable service
  • No active signal
  • Sound quality
  • Low maintenance costs
  • Multiple positioning platforms

Type of PBX System

With so many business benefits, it is clear that businesses want to implement PBX as their preferred telecommunications system. 

Once you’ve decided on a PBX as your solution, it’s time to choose between the 5 PBX options. Here’s a look at the system.

Analog (or commercial) System PBX

A traditional analog system connects callers through multiple phone lines; However, it uses conventional cables such as copper wire for this connection. 

It has all the main features of analog PBX:

  • Extension
  • Transfer
  • Silent
  • Roll Back
  • Fast Forward
  • Digital Response Assistant
  • Voicemail
  • Send a Call

Analog networks are best suited for businesses in remote areas where Internet connections may not be reliable. 

This is a standard PBX system that offers reliability, good sound quality, but it is not the first choice for businesses that want to expand and grow.

On-Site VOIP PBX System

The next step in PBX systems is Voice over IP (VoIP), which uses an Internet connection instead of traditional copper cables. The system here leverages your business’s internal systems to improve phone stability, sound quality, and provide more programming than older models.

These features or applications include:

  • Voicemail to Email
  • Mobile Integration
  • Video Calling
  • Caller ID
  • Call Waiting
  • Auto Attendant Options

Although initial installation costs may be higher than an analog PBX system, the cost savings more than pay off in the long run. In fact, business VoIP can save businesses up to 50 percent on average phone bills. VoIP is easier to maintain than traditional PBX and is only limited by bandwidth.

Hosted PBX

Unlike legacy, on-premise or hybrid PBX, hosted PBX is a type of virtual PBX where PBX services are provided using broadband services. There are no physical devices in this setup. 

This also means that you need to deploy or install third-party software or hardware to make business communications.

In a PBX hosted by Asterisk2Voip, there are no phone lines involved and all communication is done through SIP trunk technology. You just need to have a pre-configured IP phone. After that, it’s plug-and-play. 

Once connected to broadband, our hosted PBX uses your Internet connection to make and receive calls and provide enterprise-class PBX services.

Hosted PBX is a modern solution for PBX services and gives your team and clients the freedom to connect from anywhere in the world. 

To provide PBX services, you can host your services on any server – built-in or third party.

Not only is it cost-effective, but it also provides remote support, cloud support, and many other important benefits.

Hybrid PBX system

It offers many IP extensions that integrate existing PBX equipment with VoIP, connecting the phone to the office. 

Some of the features of this PBX system include:

  • Virtual Conference Room
  • Fax From IP
  • Video Conference
  • SIP Stem
  • Automatic Attendant
  • Hold The Queue

With a hybrid PBX system, if the legacy PBX or VoIP server fails, the system can be switched to another network, making it ideal for remote offices and secondary locations. This is a great option for temporary locations, such as construction sites, with cordless phones connected to a hybrid PBX system without using the building’s phone lines. 

A hybrid PBX by Asterisk2voip is especially suitable for businesses that want to have a phone system in places where reliable phone lines are needed. 

It can eventually be upgraded to a cloud-based PBX if needed.

Cloud PBX

Cloud or SaaS is the most advanced PBX system provided by Asterisk2Voip. With a cloud-based PBX system, you have complete control over managing all of your PBX operations.

Being a virtual PBX allows businesses to overcome space and cost constraints. It helps you connect all your devices to a cloud-based phone system. 

After that, you can add a lot of customization and integrate your system with SMS and other important services using the application programming interface (API).

Like an on-premise PBX, a cloud-based PBX does not need to be located anywhere. As an application, you can monitor your phone flow using a virtual interface on your PC.

Cloud PBX also uses VoIP and must always be connected to the Internet to ensure excellent uptime. Cloud PBX is the technology of the future, everything is done from your computer and you don’t need to rely on third party services. All updating activities can be easily done online without harming your data and without facing technical problems.


When choosing the right PBX solution for your business, it’s best to work with industry experts who can advise you on the right features, costs, and requirements. 

Asterisk2Voip is the market leader in voice solutions offering a wide range of cost-effective voice, data and hosted services.
