Benefits of VOIP for business


Advancements in telecommunications technology have turned a lot of models of business communications on their heads which have changed the way many companies communicate internally, and with their customers.

Few developments have had as much of an effect on this as VOIP infrastructure, like that of our SkyVoice Business solution, which has brought numerous benefits to businesses everywhere.

VOIP or Voice Over Internet Protocol delivers a voice calling service, much like traditional landlines, that are operated over internet protocol networks, making it function and cost, much in the same way that an internet connection would.

Let’s take a closer look at how this as benefitted those businesses (and even homes) that use this solution:


One of the major advantages that businesses can glean from VOIP solutions is a significant long-term cost in running costs, mostly due to the fact that VOIP makes use of internet protocol infrastructure instead of a fixed landline, to facilitate voice calls.

When you compare the difference in costing models between fixed landlines and internet lines, it is easy to see why.

Fixed landlines come at a cost per use, which means that the more calls you make (and depending on where those calls are being made to), you end up paying more because of a per-minute or per-second costing model.

Any business with a telesales department using a fixed-line for calls already understands how quickly this can result in mounting costs.

A VOIP line, on the other hand, being one that is tethered to internet protocols, has a costing model similar to that you would get from any uncapped internet line, which means that it is costed to a once-off or fixed monthly fee that will not rise depending on how many calls you make.

If your business generally spends a lot each month on calls being made from fixed lines, this is a massive advantage that compounds the more reliant you are on your phones.


Local telecommunications lines often leave something to be desired in terms of the call quality you get from them, often with results that vary from day-to-day. A crackling phone line with static in the background making it near impossible for the person on the line to hear you, does nothing for your business, especially for those precious moments where it needs to relay important information or pique a prospect’s interests over the phone.

Clarity can make all the difference, and let’s be honest, fixed phone lines don’t always provide it.

By working through ha quality internet line, such as fibre, LTE, or ADSL, VOIP services can drastically improve the quality of your calls, assuming you have access to a stable internet connection.

VOIP uses very little data, so even with an internet connection that has high bandwidth needs, you will still enjoy a crisp voice line from your phones, every time.


Uptime on phones has been a concern surrounding them since they were first widely used, but having a dependable phone line for your business that you can rely on to keep communication flowing, is arguably essential for any business, of any size.

Networks working off of old phone lines, for many reasons, simply cannot offer this kind of uptime and reliability.

Firstly, here in South Africa where cable theft is a daily reality that often interrupts service deliveries. Exposure to bad weather is also a common issue that makes phone lines unresponsive, and repairs for both of these issues can be a timely affair that leaves you without a point of communication.

Then of course there is a general lack of maintenance that often occurs on fixed-line infrastructure, particularly if your business works in a remote location that sees little attention. All of these issues can cause serious complications for your business, often incurring additional costs when you need to use a temporary, alternative solution, like mobile phones.

Being tied to an internet protocol, however, VOIP is as reliant as your internet connection, which can be a huge benefit for those with access to reliable internet, like LTE (especially in remote areas) or indeed, fibre.

This means fewer interruptions to your communications for any business with access to the internet, which should, at this point, describe most of them.


A common area of concern for businesses opting to change the way and tech they use communicate is whether or not they will be able to keep their existing detail once they make the move.

This is an understandable concern, as a simple number change can mean a lot of complex alterations to other parts of your business.

How many business cards, letterheads, invoices, and ads will need to change? The cost of reprinting and redesigning these items might be one you don’t want to have to deal with.

What about your website, social media pages or any other type of online advertising? Having to change your number means getting in touch with these agencies and seeing to it that the changes are made.

Worse still, what about those clients who have your number saved, but have no other way of contacting you? Are you to just leave these clients in the hopes that they will find your new details somewhere down the line?

Fortunately, with VOIP services like our SkyVoice Business solution, you can keep your old or existing numbers by simply porting them over to the new system, and it will be as though nothing had changed, except that your calls will be clearer, more reliable, and much cheaper overall.


With the right VOIP package in place your business can even circumvent the costs that are generally associated with routing calls to numbers across various cellular providers. For instance, if you want your salespeople who are out on the road to have calls made to the office forwarded to them, you would normally have had to set up call forwarding through a system like a PBX in the past.

While this is still a fairly common way of doing things in businesses with high volumes of calls and intricate communication networks, there is a cheaper and much easier way…

Our service for Sky Voice Mobile for instance lets you use the VOIP infrastructure to forward or route cellular calls over Wi-Fi, cutting the cost of call forwarding by disintermediating mobile operators and instead using your internet connection at the office, and not requiring expensive equipment like PBXs to do it.


There are plenty of excellent reasons to opt for VOIP services like our SkyVoice Business and Mobile packages.
