Business VoIP allows users to make calls over internet-enabled devices. The user's voice is sent over the internet, as opposed to a PSTN, which makes traditional phone calls possible. VoIP calls are mostly in the cloud, but some systems may require certain types of VoIP equipment and hardware to operate. The hardware is what can transfer your existing phone system into one that is completely internet-based. This software can be installed on these devices in one of two ways — on-premise or hosted.


On-Premise Software vs. Hosted Software

On-premise software means that the solution is run on a local server or IT infrastructure located in your office. This allows for extra security and control over your software, but also tends to come with an extra cost of managing an in-house server. Hosted-software is the more common way to run your tools these days.

This means that a third-party provider houses the server for your business, and you can access it through the cloud. Taking this route means you can pay on an as-needed basis and scale your solution up or down as you please. Hosted solutions are becoming the more popular way to run your software as it's cost-effective and takes up less physical space in your office.

No matter which route you take, these processes are what will get your VoIP hardware up and running. In this article, we'll discuss the types of hardware you may need for your VoIP systems and the best vendors to purchase them from.


Types of VoIP Equipment

IP Phone


You’re going to need some additional hardware to get your phone service up and running. Here’s a list of some common items you may need:

Analog Telephone Adapter — This device, also known as an ATA allows you to use a standard phone to make calls over an IP network. An ATA is a vital piece of hardware for an IP phone.

Channel Bank — This device converts analog signals that typically travel over phone lines to digital signals that can travel over the internet.

Ethernet Cable — As mentioned above, this type of phone requires this cable to connect to the internet. The cable provides wired connections to the internet.

IP Phone — An IP phone, also known as a VoIP phone, is a physical phone system that utilizes VoIP technology instead of a traditional phone line. The phone connects to the internet through an ethernet cable that has plenty of internet bandwidth, which then connects to the IP address of your VoIP provider.

PoE Adapter — This device, also known as a PoE injector is what physically powers an Ethernet cable. The cable is plugged into the tool, which is then plugged into an outlet, allowing the cable to work.

Uninterruptible Power Supply (UPS) — This device is essentially a battery backup. Since IP calls rely on electricity and an internet connection, this will allow you to make a call in the event of a power outage.

VoIP Gateway — These gateways act as a bridge between a traditional phone infrastructure and a computer network. This device converts analog phone signals to SIP (Session Initiation Protocol) and vice versa. More robust gateways can up to 256 calls at a time.

VoIP Headset — These devices can be used in any VoIP call. They are headphones with a built-in microphone. This isn't a vital piece of hardware for your phone system, but it will allow you to go hands-free while you take a call.

IP PBX Server –  An IP Private Branch Exchange (PBX) Server is the metaphorical center of your phone system. This device is a computer server that routes your call through the appropriate channel to connect you to the internet.

VoIP Router — A router directs internet traffic by passing data packets between computer networks. This is what connects your VoIP-enabled devices to the internet and is responsible for your call's quality and connectivity.

Keep in mind that you won’t need every one of these devices in order to implement a powerful VoIP phone system and take advantage of these top VoIP features. It all depends on the provider you go with.
