1. 4Com Review โ€“ Best VoIP Provider Overall

4Com began operations in 2001 when it was founded by John Kunasch and Donald L. Brown, who were veterans of the telecom industry. 

The company was initially based in Kankakee, Illinois, founded on the principles of providing quality services at affordable prices. In fact, the company's tagline was "Quality at Affordable Rates."

With over 15 years under its belt, the company became a great success in the VoIP market. However, it was not without its growing pains. In fact, in 2014, the company filed for bankruptcy. The team behind 4Com quickly got things back on track and were able to pay off debt in just a few months with the help of a corporate investor.

How It Works

4Com uses VoIP technology, which isn’t all-to dissimilar to how virtual private servers work, to allow businesses to communicate with customers and employees on a 24/7 basis. These calls are made via a digital network, which allows the call to be routed through a server and end with a series of tones. 

This means that the calls made using 4Com’s services don’t require a phone line or a dedicated IP address. As such, the calls are completely secure and private and don’t require the use of public phone lines. However, as businesses often need to make emergency calls, 4Com also offers an “Emergency Call Service'' that allows users to place a patchy or unscheduled call.


All calls made using 4Com’s VoIP service are charged at a flat rate of £0.0050 per minute. However, there are different fees that apply depending on the destination and the duration of the call.

What Are Its Main Features?

  • โ˜‘๏ธ Fully managed service: No need for any technical know-how or phone equipment. All you need is a computer or an Internet-enabled device to make and receive calls. 
  • โ˜‘๏ธ Call forwarding: Forward all your calls to another number. - Online/desktop attendant: Use an online/desktop attendant to answer your calls, schedule appointments, and send messages. 
  • โ˜‘๏ธ 3-way call: Create a three-way call where one person speaks and the other listens to their conversation. 
  • โ˜‘๏ธ Call recording: Record all your calls and play them back at any time. 
  • โ˜‘๏ธ Number portability: Transfer or change your phone number at any time. 
  • โ˜‘๏ธ Cost per click: Purchase a click to place a call or send a message to the recipient.

3. Vonage Review โ€“ Best for Reputability

Vonage has been around for decades, and it’s grown to be one of the world’s most recognizable telecommunication brands.

It is well known for offering quality phone services at low prices with friendly customer service.

Vonage services are available in many countries, allowing you to make cheap international calls.


Vonage was started in 1995 as a division of WorldCom. The company was later sold to Symantec. In 2010, it was acquired by private equity firm, Audax Group, which renamed the company Vonage Holdings. The company was then bought by ACM Equity Partners in 2014, who renamed it Vonage. The telephone service began in 1995 when WorldCom decided to enter the telecommunications business. 

The company formed a division called Vonage under WorldCom’s Advanced Telecommunications Group (ATG) division. The division was focused on making VOIP - or Voice over Internet Protocol - calls. By the year 2000, Vonage had launched its first product, Vonage Virtual Private Network (VPN) Service, which is notable even though it does not rank as one of our best VPNs

How It Works

Vonage offers phone plans that provide a service called “iMo”. The iMo service enables you to “immerse yourself” in the sound of your phone calls by providing the best quality of sound. If you are making a call on your Vonage phone, the call is encrypted and transmitted to Vonage’s servers. The Vonage servers then route the call to the recipient’s phone, which then receives an encrypted sound. 

What’s more, it’s free! Vonage offers a variety of phone plans and options. Plans are available at different price points, and they provide different number of minutes and connection speeds. To choose the right plan, you have to consider your calling needs and requirements. For example, if you are a heavy user, then you can opt for a higher-priced plan with higher monthly rates and high connection speeds. 

On the other hand, if you have a business that relies heavily on phone communication, then you can opt for a cheaper plan with less calling minutes and low connection speeds.



Vonage may sound like a really good deal, but it’s important to know the fees that you’ll be charged. Vonage currently has tiered pricing for all of its plans. For example, the basic plan starts at £16 per month with 500 minutes of calling. 

The next plan is the £24.65 per month plan with 1000 minutes of calling. The £32 per month plan is the most expensive with 5000 minutes of calling. Once you select the plan that you want, it’s important to keep in mind the fees that you’ll be charged. 

If you were to select the basic plan for around £16 per month, then you’ll be charged an additional £1.60 per month for the gateway fee. Similarly, if you were to select the most expensive plan, you’ll be paying £16 per month plus around £4 per month surcharge for the gateway fee. It’s important to know these fees. Otherwise, you’ll be paying more than you need to.

What Are Its Main Features?

  • โ˜‘๏ธ Free International Long Distance Calling: Not all telecommunication providers offer free international long distance calling. The calling feature helps you save a lot of money. You can make as many international calls as you want as long as the calls don’t go through your local phone. 
  • โ˜‘๏ธ Voicemail: You can set up your voice mail account with Vonage. You can view your voicemail and listen to the messages by calling your Vonage phone number. You’ll be prompted to enter your password to listen to your voicemail. 
  • โ˜‘๏ธ Three-Way Calling: With three-way calling, you can dial another number and have the recipient dial back to your number. 
  • โ˜‘๏ธ Call Forwarding: You can set up call forwarding on your Vonage phone. When you call another number, the call will be forwarded to your phone number or vice versa. You can set call forwarding to be automatically enabled or disabled. 
  • โ˜‘๏ธ Speed Test: You can use the speed test to check your internet connection. The test will help you determine the download and upload speeds while you are on the internet. 
  • โ˜‘๏ธ Remote Access: You can use Vonage to remotely access your device. This can be useful if your device is locked or you want to check your device when you don’t have an internet connection.

Buying Guide

Before you select your perfect VoIP providers UK company from our above review, let’s cover more background essentials.

To Start With - What is VoIP?

For those who are new to the whole world of voice over internet protocol, you might be wondering if it has anything to do with the internet. The answer is yes, both are related. 

Voice over IP is not just phone calls that are sent through the internet in  “uncensored” countries, it's voice calls that use the internet to transfer the sound signal between two parties. 

What is VoIP

VoIP is basically using our existing phone lines to send and receive calls over the internet. This is a great way to stay in touch with loved ones while they are overseas, or to do business with people who live in another country.

VoIP is different from regular phone services in several ways. First, it uses your existing phone wiring rather than dedicated lines or lines in the cloud. Second, it does not use a dial tone, and so you must have an internet connection to use it. Third, the sound quality is lower than what you get from a landline phone.

How VoIP Works

In order to use VoIP, you need a domestic or international phone line and an internet connection. Calls are placed using SIP and routed over an IP network. Voice-over-IP is an electronic method of transmitting sound through computer networks. The sound is digitised and then converted into an analog wave for transmission. This process is called digitalization. 

The voice is then converted back into digital format for reception by the other person’s phone. Similarly, the other person’s phone converts the analog wave back into digital format for transmission. This process is called demodulation. You can see that the VoIP system relies on computer-to-computer transmission of sound.

Why Should You Use VoIP?

โ˜‘๏ธ Stay in touch with loved ones while they are overseas. 

โ˜‘๏ธ Protect your personal information and keep your online activities private. 

โ˜‘๏ธ Combinatively, you can use a virtual private network to connect to the internet when you’re out of the country.
