About VoIP

What is VoIP?

VoIP stands for Voice Over Internet Protocol, or more commonly, Voice Over IP and is usually pronounced as ‘voyp’. VoIP is also sometimes referred to as an IP Phone system.

How does VoIP work?

Simply explained, VoIP refers to making calls that are made over the internet rather than over an analogue line, commonly referred to as landline or PSTN.

Using a VoIP service allows you to make and receive calls from almost any device as long as you have an Internet connection using unified communication apps. This makes a VoIP phone system ideal in scenarios such as the Coronavirus / Covid-19 pandemic where users need to work remotely.

VoIP advantages and disadvantages

What are the benefits of a Voice over IP phone system?

Reduced set-up costs and installation time
Decrease in costsSome providers, such as ourselves, offer a fast turn around on VoIP orders – including same day. Furthermore, in most cases there is usually no set-up costs for a VoIP phone system however this is dependent on your provider.

Reduced call costs
Compared to calls made via a landline, IP call costs are considerably less. In most cases, you may find your VoIP provider offers inclusive calls like we do.

Call recording
With most VoIP solutions call recording is available, most of the time at an additional cost. However, call recording can be important if you take verbal contracts or even for training and monitoring purposes.

With our VoIP solution, we can provide call recording and call recording storage for up to 7 years. Furthermore, you can even start, pause, stop and resume call recording live during a call.

Advanced features
From advanced call routing with voice menus to advanced call analytics – VoIP offers a lot of features that businesses may find critical. One popular feature we like is BLFs (Busy Lamp Fields). This feature allows users to see if another user is on the phone, saving a users time needlessly putting calls through to a user who is unavailable. This feature bundled with the many others is why a recent study found staff save around 32 minutes a day when using a VoIP service.

What are the disadvantages of VoIP?

Internet connection
One obvious downside of a VoIP phone system is that it is heavily reliant on an internet connection. Which means if your Internet goes down, you will be unable to place any outbound calls using your device. However, with modern solutions such as VoIP mobile and desktop apps and 5G broadband back-up solutions this issue should not be as prevalent.

As well as an internet connection, VoIP phones are reliant on always having power; meaning if you don’t have power, you are unable to dial out. This is again mitigated if you use the mobile or computer app.
