What Are Business Phone Systems?

Business phone systems, like residential phone systems, give businesses a way to manage all their ingoing and outgoing calls. Unlike residential systems, business phone systems have several additional features for more complex call management, such as:

  • Multiple lines. Businesses can allow employees and callers to switch between multiple phone lines to field several calls simultaneously.
  • Conference calls. Conference calls allow multiple people to participate in the same call at a designated time. Conference call features are an important component of modern hybrid work environments.
  • Call forwarding. With call forwarding, businesses can send calls to different levels and even email addresses.
  • Call holding. Call holding allows you to hold calls until a staff member can answer the phone line. You can even add music for the caller to listen to when on hold.
  • Headset support. Business phone systems have wireless and wired headset compatibility to reduce the fatigue of holding a phone up all day.
  • Visual voicemail. Visual voicemail services not only store messages but can also transcribe and send them to the intended recipient via text or email.

What Are the Different Phone Systems for Small Businesses?

Modern offices use three main types of business phone systems: KSU, PBX, and VoIP. Below is a summary of these types of phone systems and their pros and cons. 


Key system units (KSUs) are one of the older models of office phone systems and are usually used by small businesses with fewer than 40 employees. These easy-to-use systems carry all the standard features a small business would want, such as operators, voicemail, and call waiting

The main feature of a KSU is the central unit, which operators use to switch phone lines and direct calls. Some KSU systems do away with the central unit and have a wireless setup. Generally speaking, these are the cheapest kinds of business phone systems. 

The main downside of a KSU is its relative inflexibility. KSUs typically only have up to 40 phone lines and do not allow many options for company growth. They’re best suited for smaller businesses that don’t have plans for growth.


Private branch exchange (PBX) systems are more advanced phone systems and have programmable central units, which does away with the need for individual operators. These switching devices can automatically reroute calls to the intended recipient. 

PBX systems have a lot of automation and are better suited for larger businesses. High-end PBX systems have a diverse range of features for businesses, like call holding, call forwarding, voicemail, and more. Many PBX systems also have a separate power unit so you can still use them in the event of power outages. 

The main benefit of PBX systems is their scale and flexibility. Some of the largest businesses use turnkey PBX systems to manage hundreds, if not thousands, of calls every day. PBX systems require substantial hardware installation, so they are usually more expensive than KSU systems.


Voice over internet protocol (VoIP) is a relatively recent type of phone system that uses internet connectivity to provide phone functions. VoIP phone systems are highly scalable and can directly interface with your existing internet connection, reducing hardware and installation costs. 

Business owners can opt for self-hosted versions of VoIP systems. However, since VoIP systems rely on an internet connection, you cannot use them when the internet is down. The upshot is that VoIP systems provide fast connections with the clarity and speed of a high-speed internet connection. 

Another benefit of a VoIP business phone system is how you can use the protocols on different devices, like smartphones or tablets. However, internet latency issues mean you can experience stuttering and lag on calls. If you want something scalable, then VoIP is most likely your best choice.

We realized that our business needed more from our technology than we were getting. It seemed like things were always needing fixing or breaking at just the wrong times. We thought we were saving money by having one of our employees support our IT. When we looked at how we were pulling him away from his core responsibilities, how often we were down because of an issue and the knowledge we just didn't have in house, we were actually spending enough money to afford a professional IT partner - Succurri IT. They provided us with a technology assessment and visited our office before coming up with a plan for us. They helped us get our IT department in order and modernized. We are in a different place and extremely happy with the predictability we now have.
