Imagine the situation: a potential customer calls the sales number listed on your website. Your salesperson picks it up, answers a few questions, and closes the sale. Fast and easy, right?

For any company, business communication is crucial for defining the customer experience that the brand cultivates, which can be a determining factor for survival.

With the right VoIP phone service, you can improve customers' and employees' experience.

Business VoIP services are easy to use and take minutes to set up. Besides, VoIP tends to cost a lot less than traditional phone plans.

There's a great variety of good business VoIP phone services, but how to decide which one's right for you?

In this article, we'll compare the best business phone services (VoIP) to help you decide the best one for your business needs.


Business VoIP is an internet-based business phone service that allows you to receive and make phone calls using computers, VoIP phone sets, and also mobile devices.

VoIP business phone service comes with a wide range of extra features for which you don't have to pay extra, like call forwarding, call waiting, digital receptionist (auto-attendant), voicemail, video conferencing, caller ID, and others.

Moreover, many also offer integrations with third-party software like email providers, CRM and project management platforms, and more. As an all-in-one tool, VoIP service providers can unify your internal and external communication tools, saving both time and money.


Without paying for multiple lines, you can use separate numbers for personal and commercial purposes.

Multiple numbers

No equipment is required

Compared to separate telephone lines, these numbers are easier to set up and maintain. There's no need to buy additional equipment for each number, and most virtual phone providers don't require long-term contracts.

Ease of use

You can quickly and conveniently manage your numbers on the Internet. It's possible to instantly purchase or cancel them at any time.

Added features

These numbers often include more features than a standard cellphone or landline service. They simplify call recording and the process of arranging video conferences.

Brand multiple businesses

If you run multiple small businesses, it's not difficult to introduce different virtual numbers and voicemail greetings for separate companies.

What features are most important for keeping your employees and clients in touch? Call forwarding, call waiting, conference calling, and caller ID are some of the beneficial options available with Voice over IP. But are they just bonuses for your business? Or are they essential to how you communicate with your clientele? Evaluate what your company needs from its VoIP service to ensure that the providers you research offer the features you need.

Determine What Features You Need

Narrow Down VoIPs that Fit the Bill

Once you have decided on features, it's time to think how much you would pay for a VoIP. Look at your current telephone bills and other communication software expenses you incur. Note down all the features you pay for and compare them with the VoIP offerings you need.
But before narrowing down your options, also take the "bundled services" of your current communication system. You might be enjoying an Internet plan or media streaming package with your existing telephone line. VoIP service won't provide those.

Verify That the VoIP Provider's Service Will Work with Your Equipment

Determine if a VoIP provider's service will work with your equipment by looking at their website. Plenty of providers offer full lists of supported devices, and some will also work with you depending on your existing phones and internet routers. VoIP providers also, in some cases, have testing tools on their website to determine if your internet connection will support their services, so be sure to check.

Read Reviews

This is where you verify the information you got from the company itself, at least to some degree. Don't take all reviews close to the heart, as many people are more apt to write a bad review than a good one. However, if you're consistently seeing complaints about the same problem with a particular VoIP provider, especially if they are recent, avoid this option.

Third-party Integrations

Apart from the call handling services of a VoIP, also check for its integration with other support systems.

Integrating the VoIP system with your preferred CRM software or cloud storage service will significantly simplify your business processes.

Make sure that the VoIP service provider offers such options. Even if the VoIP doesn't integrate with a particular application, it should support third-party API integrations.
Concerning third-party API integrations, it is essential for the business VoIP service to integrate with Twilio. Twilio is a developer platform for cloud communications. The success of any business is based on effective communication. This is what Twilio offers.

Twilio is taking a global telecom network and transforming it into a communications API. Developers use already familiar web languages and create communications experiences that weren't possible before in that short timeframe.

Information that is available in software systems is used to route communications to the right place and to the right person.

Twilio enables to do:

▪️ Text messages
