Top 11 VoIP Providers for UK Small Businesses

Written by on August 31, 2016

VoIP, or Voice over Internet Protocol, is a phone service that you can get with only your Internet connection and no landline phone company required.

Avoiding the long tech explanations and unnecessary terminology, a phone or an adapter turns phone signals into digital ones and sends them across the Internet.

So why use VoIP?

First, to save money. Generally, VoIP services are cheaper than traditional phone services, especially when we’re talking about roaming calls.

Second, they include way more functions. You can have your clients redirected to your mobile number while you’re enjoying margaritas on the beach.

We’ve collected the best VoIP service providers that will help you stay in touch with your customers.

To sum up:

Depending on your business specifics, you may consider choosing different solutions. For example, if you have 1-2 client calls per week, it makes sense to think about a VoIP provider that charges on a per minute basis without fixed contracts.

In case you have a large number of calls per day, consider monthly contracts, adding voicemail and other add-ons to improve the customer experience and save more money.
