Why does VoIP Need a Good Internet Connection?
July 24, 2019

Why does VoIP Need a Good Internet Connection?

You've most likely heard of the term 'VoIP'. VoIP uses your broadband connection to make and receive calls; rather than the PSTN. This makes your calls cheaper (or even free), can improve your call quality and even cut dramatically reduce your running costs.

Whilst VoIP has been around for a long time, it is widely considered to be the new, more modern alternative to traditional telephone lines. VoIP uses data packets of voice to make calls - rather than

But, why does VoIP need a good internet connection?

Because VoIP uses your broadband connection, it requires a good internet connection. Typically, your businesses broadband connection only sends data from emails, browsing the web and other online activities. However, with VoIP, your broadband also sends your voice.

It's a bit like a motorway. Typically, you just have cars on the motorway - which are your browsing and emails etc. However, with VoIP, you are adding bigger trucks to the motorway alongside the cars. This means that your motorway (or broadband) needs to be big enough to contend with this extra traffic.

How fast does my broadband need to be for VoIP?

As a guide, Commsplus would recommend that a minimum speed of 28Mbps download is required for a stable, reliable VoIP connection. With most businesses using fibre broadband, this is more than achievable; in fact, you probably already have the minimum recommended speed.

What if you don't have the required 28 Mbps?

Technically, even if your business doesn't have the minimum recommended speed, you can still get VoIP. But it won't be as reliable, you may suffer dropouts as well as quality issues.

You could look at upgrading your business broadband to a fibre broadband connection, or upgrade your package if you already have fibre broadband. However, we appreciate that some businesses may not be able to get a fibre broadband connection, due to their location.

If you can't get a fibre connection, then you may want to look at other options, such as a leased line, or a 4G broadband connection.
