Over the years, more and more companies have gone through digital transformation. This is because business leaders—from small businesses to big enterprises—recognize the importance of digital tools to improve business processes, increase staff productivity, and boost team performance. 

One of the most important tools that every organization should have is a robust business phone system. After all, business communications can determine the success or failure of a company. 

If you want to be successful, you need to equip your employees with a communication tool that they can use to talk to each other and collaborate on projects. More importantly, they should be able to use it to stay in touch with customers. 

As work setups move from traditional offices to remote work or hybrid work, it’s now more important than ever to find ways to keep your distributed workforce connected at all times.

The good news is there are various business phone solutions in the market for you to choose from. 

If you’re a small business owner who wants to narrow down your long list of choices, you can start by checking out what VoIP phone service is, what are the best VoIP solutions out there, and how to find the right one that can address your business needs.

What is VoIP?

VoIP stands for Voice over Internet Protocol, the technology that allows people to make or receive phone calls using a broadband Internet connection instead of a traditional landline phone.

With VoIP calls, you’ll get the flexibility to use different devices for phone calls as long as they’re connected to the Internet. For your workforce, this means that they can work from anywhere.

How to set up a VoIP phone system for your small office

Business VoIP providers like RingCentral make the VoIP setup process simple, easy, and hassle-free.  

You only need to accomplish two important things before you start the installation of your small business phone system—

1. Check if you need to upgrade your Internet plan

Your VoIP phone system won’t work effectively if you don’t have a strong broadband connection. This means securing one should be your top priority. 

If your small business requires you to make a lot of calls using many different devices in a month, then you need more bandwidth. If you don’t have enough of that, you can’t ensure call quality and avoid connection issues. 

VoIP service providers recommend having a minimum of 100 Kbps upload and download bandwidth per line. 

Consult with your Internet service provider to check if you need to upgrade your existing Internet plan. Check if they’re offering a gigabit broadband connection plan to get more bandwidth. 

Remember to take into consideration that there are other business-related activities that consume bandwidth outside of Internet-based calls. 

This includes web browsing, sending and receiving emails, file transfers, and so on. Keep in mind that the number of devices connected to your network can also affect your Internet speed.

2. Find the right VoIP equipment

You need to have the right equipment to ensure that your VoIP phone system is working properly. Take note that you don’t necessarily have to buy new equipment if you already have existing IP-enabled devices. 

If you want to explore your choices, here are some of them:

VoIP phones

VoIP phones are specially-designed devices for placing and taking calls over the Internet. There are two types of VoIP phones:

  • Hard phones are physical IP phones that look a lot like regular telephones. Some examples of hard phones are office phones such as desk phones, wireless phones, conference phones, and USB phones.
  • Softphones are software-based IP phones. Internet-connected devices like computers and mobile devices can be used as a hard phone when a VoIP app (like the RingCentral App) is installed.

VoIP headsets

VoIP headsets are headphones that include a microphone. There are wired and wireless options available. Wireless VoIP headsets use Bluetooth to connect to a device.

Quality of Service (QoS) routers

Quality of Service routers help VoIP by prioritizing voice or call traffic over other transmissions like file uploads and downloads, streaming, and gaming. A QoS router allows you to choose specific applications and categorize them based on low to high priority.

Analog telephone adapters (ATA)

Analog telephone adapters are devices that let traditional landline phones use VoIP services by converting analog signals into digital data. With an ATA, you only need an Ethernet cable to connect your landline phone to either a router or modem.
