Top 17 VoIP Software Services | Business Phone Systems

May 30, 2024Business, Consulting, Digital Transformation, technology0 comments

Despite being highly connected, most customers still prefer to resolve issues and get contacted over the phone. The phone itself is not outdated, but the old analog phone systems are. In the past, analog systems were the only option, and many organisations still use them, even though they are costly to run and implement.

Nevertheless, recent technological innovation has brought about digital business phone systems like Voice over Internet Protocol (VoIP) phones. The good news is that switching to a modern VoIP phone service is easy and straightforward. The challenge is choosing the right provider from the many options available.

That’s where we come in. In this article we intend to answer some of your pressing questions about VoIP Software Services, and give you access to our IT experts for easy implementation, migration, and training. But before we get down to business, take a look at the table of content below:

What is VoIP Software?  

VoIP (Voice over Internet Protocol) is a way to make phone calls using the internet instead of traditional phone lines. For businesses, VoIP phone services are hosted on the internet and can be accessed through an app on your computer or mobile device that’s connected to the internet. This allows you to make calls using your internet connection instead of a regular phone line.

How does a VoIP business phone system work?  

VoIP uses the internet to handle phone calls. When you make a call, the VoIP app sends a signal to the VoIP servers, which then connect you to the person you’re calling. This process also works for transferring calls or putting callers on hold.

How is VoIP different from a traditional phone system?  

VoIP uses the internet, while traditional phone systems use phone lines. This means VoIP is usually more affordable, easier to scale, simpler to set up, and offers more features.

Does business VoIP include international calling?  

Most business VoIP solutions offer international calling, but the specifics may vary. Some services may require a higher tier plan or charge based on usage. Either way, international calling is generally more affordable with VoIP than with traditional landlines.

Why do I need a VoIP service for my business?  

VoIP is beneficial for businesses of any size. It eliminates the need for hardware investment and makes changes easy. You can add new phone numbers, agents, and adjust call routing and configuration with ease.

What internet speed do I need for VoIP services?  

The FCC recommends a minimum download speed of 0.5 Mbps for VoIP calls. However, your internet speed may need to be faster (around 50 Mbps) if you have multiple agents making calls simultaneously.

What do VoIP service providers offer?  

When considering an investment in your business, you want to know what benefits you’ll receive. VoIP service providers offer several advantages:

  • Quick setup: Get started in less than a day, unlike traditional landline systems that take weeks or months to set up.

  • Remote access: Manage your phone system from anywhere with internet access, ideal for remote call centres or flexible workforce arrangements.

  • Mobile access: Use your phone system on mobile devices with most business VoIP services’ mobile apps.

  • Easy scalability: Adapt to changing business needs quickly and affordably without hardware dependencies. Upgrade your plan for advanced features or add new users effortlessly.

  • Flexibility: Add new users, phone numbers, and features as needed without installing new lines or equipment.

VoIP service providers simplify your phone system management, allowing you to focus on your business growth.

What types of VoIP are available?  

Cloud VoIP  

Cloud VoIP is a cost-effective option for businesses because it doesn’t require special equipment on your premises. A third-party provider hosts the service, and you make calls over the internet. You’ll need a stable connection and good bandwidth. Your provider will likely offer advanced features like call analytics and routing.

On-premises VoIP

With on-premises VoIP, you install special equipment at your location. This gives you more control and security, but it’s more expensive to set up and maintain. Scaling up can also be tricky and costly, as you’ll need to buy more equipment and configure it.

What features do business VoIP systems offer?  

Automatic Call Distribution (ACD) and Interactive Voice Response (IVR):
ACD routes calls based on your custom rules, while IVR greets callers with menu options to connect to the right extension, department, or agent.

App and Software Integrations:
VoIP’s digital nature makes it easy to integrate with apps and software you already use, like CRMs or a marketplace of hundreds of apps.

Basic and Advanced Calling Capabilities:
VoIP solutions offer standard call features like:

  • Call waiting, transfer, blocking, and forwarding

  • Conferencing and 3-way calls

  • Voicemail, caller ID, and call masking

  • Call monitoring, recording, whispering, and takeover

  • Call forwarding

  • Omnichannel communication, Analytics, and Automation for repetitive tasks.

Note that not all plans may include all features, but upgrading to a higher tier can provide your team with the necessary tools for a cost-efficient phone system.

Business VoIP vs. Landline: Pros and Cons  


Landlines use a separate network called public switched telephone network (PTSN) and don’t rely on the internet, making them more reliable in terms of downtime. VoIP, on the other hand, relies on the internet, so if it goes down, your phone service does too. However, landlines can still be used during power outages.

Call Quality:

VoIP call quality depends on your internet connection. If it’s good, VoIP sounds as good or better than landlines. But if your connection is poor, landlines might be better.

Features and Benefits:

Both VoIP and landlines offer similar call features, but VoIP is more flexible and cost-effective. VoIP plans can be upgraded easily, and you don’t need new hardware. VoIP also integrates with other apps like CRMs and email, making it more efficient.


VoIP is generally cheaper than landlines, especially for long-distance and international calls. Setting up a VoIP system for 12 employees costs around £800, while a landline system costs £2,500. Adding new phone numbers or making changes is also more expensive with landlines.


Landlines require more hardware, are more complicated to set up, and take longer to implement. While this might not be a direct cost, it’s still a significant consideration.

In summary, VoIP offers more flexibility, integration, and cost savings, while landlines have better reliability and call quality (in some cases).
