How exactly does a phone system for small businesses?

First, let’s define what a small business phone system is. A business phone system is something more than just a mobile phone.  

Small business phone systems allow companies to send and receive outbound and inbound calls (at a fundamental level). However, you might also need a feature for transferring and forwarding calls, such as your cell phone. 


Small business phone systems: Types of phone lines available for the Enterprise


When choosing the best phone systems for small businesses, there are two phone line options: VoIP phone system or PBX (Private Branch Exchange), which mainly uses the traditional line.  

We will carefully evaluate the small business phone system that uses any of the above approaches: 


  • VoIP phone system:

VoIP phones work via IP technology to transmit calls. In addition to specialised digital hardware, it can also be implemented as a program (running on a computer or mobile device) that can perform the same functions. 

VoIP telephones receive sound through a microphone and convert it to data packets, which they send through networks and the internet.  

Leaving the phone to decompress the data, it plays it back for the other person to hear. 


  • PBX phone system:

Private Branch Exchange is also known as PBX. You can think of it as the internal telecommunications network of a business or organisation.  

PBX users can communicate via internal lines, along with making and receiving external calls. Call forwarding, call forwarding, call queue, auto-attendant, voicemail, etc., are features of a PBX phone system. 

An analog or digital phone line is used with VoIP or analog or VoIP systems. You can support more telephones by splitting the physical phone line into your business into multiple lines using a PBX phone system. In addition, it is free to call other users.

Budget is the most important thing to consider when choosing the right phone system for your small business. 

Consider a few factors when planning your budget, not just the amount but whether you can afford a significant investment upfront or if you need a more flexible payment plan. 

If flexibility isn’t essential, you could get away with a more traditional or older phone system. However, remember that these systems also demand more significant investment from the beginning. 

If you’re considering moving your business forward, make sure that the phone system you choose will work for your current needs and your plans.
