Pros

  • Excellent security

While most business VoIP services are designed for on-premise equipment, Dialpad is a cloud-based solution that can be used with any internet connection.

7 Key Benefits of Unlimited VoIP Calling

Although mobile communications have seen vast improvements over the last several years, many businesses are still using landlines to make calls. In addition to being expensive, these traditional phone lines can be inflexible and unreliable. VoIP systems have become a popular alternative for business owners who want to improve their communication without breaking the bank. Here are seven key benefits of using an unlimited VoIP service.

Cost-effective

One of the most significant advantages of VoIP is that it’s much cheaper than traditional phone lines. With VoIP, you only need to pay for the internet connection and hardware, which is a fraction of the cost of landlines. In addition, VoIP calls are often free or very low-cost so that you can save even more money on your monthly bill.

Flexible

VoIP systems are highly flexible, so you can quickly scale up or down as your business needs change. If you need to add more lines, you can do so without any problems. And if you need to reduce the number of lines, you can do that as well. With traditional phone lines, it’s much more challenging to make changes like this.

Reliable

VoIP systems are just as reliable as traditional phone lines, and in some cases, they’re even more reliable. With VoIP, you don’t have to worry about the line going down due to a power outage or bad weather. And if your internet connection is down, you can still make calls using your VoIP system.

Mobile

VoIP systems are perfect for businesses that need to be mobile. With VoIP, you can make and receive calls on any device, anywhere in the world. All you need is an internet connection. So if you have employees who work from home or travel often, VoIP is a great option.

Better sound quality

VoIP calls are clear and crisp, with little to no background noise. This is because VoIP uses digital signals instead of analogue signals like traditional phone lines. So you can rest assured that your calls will be crystal clear.

Advanced features

VoIP systems come with a variety of advanced features that can improve your communication, such as caller ID, call waiting, voicemail, and more. These features can be beneficial for businesses that need to stay organized and efficient.

Easy to use

VoIP systems are designed to be user-friendly, so you’ll be able to set up and use your system with little to no training. And if you ever have any problems, most VoIP providers offer excellent customer support.

How We Chose the Best Unlimited UK VoIP Providers

With so many VoIP providers on the market, it can be hard to decide which is best for your business. To help you make a decision, we considered a number of factors to make our recommendations for the best unlimited VoIP providers in the UK.

Reliability

The first factor we considered was reliability. VoIP is an internet-based technology, which means that it is subject to the same potential problems as any other internet service. However, a good VoIP provider will have systems in place to minimize these problems and keep your service running smoothly.

We looked at customer reviews and independent expert opinions to get a sense of each provider’s reputation for reliability. We also took into account the company’s history and track record.

Ease of use

The second factor we considered was the ease of use. VoIP can be complex, and the last thing you want is a service that is difficult to set up and use. For example, some VoIP providers require you to have a specialized router, while others work with your existing equipment.

So, we looked for providers that offer simple, straightforward services that are easy to set up and use.

Value for money

The third factor we considered was value for money. There are a lot of VoIP providers out there, and they all charge different prices for their services. We took into account the cost of the service, as well as the features and benefits included in each package.

We also looked at any special offers or discounts that were available. For example, some providers offer free calls to certain countries, while others include a certain number of free minutes in their packages.

Customer support

A good VoIP provider offers excellent customer support, so you can get help when needed. Even in the case of providers who promise a 99.99% uptime, things can (and do) occasionally go wrong.

There are providers who have been in business for many years and have a reputation for excellent customer service, while others are newer to the market and may not have the same level of experience.

How to Get Started With a Virtual Phone Number Provider

In this section, we’ll be going over how to set up your VoIP service. We’ll be using our number 1 best VoIP provider, Ooma, for this example.

Step 1 — Purchase an Ooma VoIP Router

 

ooma review home screen

Visit the Ooma website by clicking the link down below. From there, you’ll want to choose a Business or Residential plan based on your needs. For the sake of this review, we’re going to choose Residential but the Business process is similar.

From the home page, head on over to the Shop tab at the top of the page and select “Home Phones”. Ooma’s “Telo” service is free to use, plus you can upgrade to “Telo Air” for Wi-Fi connectivity. The LTE package does require a subscription fee, but it’ll work even through power outages thanks to a battery backup system.

ooma price plans

From there, you can pick the Ooma devices that suit your needs but you’ll need to buy at least one Ooma router to use the service. We recommend you take advantage of their bundled Handset deal so you have devices to test the service with. Remember, Ooma comes with a 30-day money-back guarantee!

ooma review handsets deal

Purchasing a handset through Ooma is a painless process, all you need to do is choose where you want your Ooma Telo sent to and enter in some basic payment details. Best of all, it’s free shipping! You can also send the devices back to Ooma if you decide you want to use their 30-day money-back guarantee.

ooma purchase screenshot

Shipping can take several days depending on your location, but once you have the Ooma device in your hands the rest of the process takes minutes to complete.

 

Step 2 — Register your Ooma device

Before you can use your Ooma device, you’ll need to register it to activate the subscription plan. Ooma is free by default, but you’ll have to enter some basic details about your usage before you can get started.

To register your Ooma device, go to “Login” on the homepage and then select “My Ooma Telo”. You’ll be taken to a login page, from there you’ll have to click “Activate my new account” to get to the registration page.

ooma review activation process

 

The activation code is located on the bottom of your Ooma router, which is helpfully pointed out during the activation process.

ooma activation diagram

After this step, you’ll be asked to enter some basic details about your location and billing if you’re going with one of Ooma’s paid plans, but it’s all pretty straightforward.

Step 3 — Figure Out Your Needs and Follow Their Guide

Finally, you’ll want to decide on everything you need to set up based on your plan and business needs. There’s hundreds of different options, which would be hard to cover in a single guide.

Once you’re done with the setup phase, all you have to do is upgrade to the World package to receive calls in the UK and you’re ready to go!

Since there’s a plethora of different options and systems, you can use Ooma’s comprehensive support section to guide your use of the software. If any part of it confuses you, don’t worry! Ooma has a 24/7 support team on hand who are always ready to help you.
