Is VoIP right for you?

Andrew Bentley


VoIP is now a commodity product. How has it reached this status without you investing in it yet? Simple. Technology doesn’t wait for people. People wait for technology. With VoIP, it’s easy to see why uptake has been rapid. The endless features and products, and the benefits that these features and products bring, have been publicised enough for every IT manager to know that VoIP is worth talking about.

VoIP Benefits

If you haven’t heard about the major business benefits of VoIP, here’s a quick reminder of the basic principles:

  • Quality: Every good VoIP service comes with Mean Opinion Scoring (MOS). This measures the overall quality of a call made over your VoIP connection. If any issues are found, MOS can identify where and when the issues took place. If you ever experience a jittery or dropped call, you can get to the bottom of the issue that caused the problem.
  • Reliability: Unlike PSTN and ISDN services, VoIP uses the internet to make calls. This means you are no longer reliant on copper lines. No copper lines means no risk of poor service due to bad weather or tampering at the telephone exchange.
  • Scalability: VoIP has no higher limit. You won’t run out of space like you did on your ISDN circuit or PBX phone system. If you need more users, we can add them.
  • Cost: VoIP consumption models enable customers to only pay for what they use – no overusage or licence uplift

VoIP as an ISDN replacement

The most common scenario for implementing VoIP is replacing ISDN. This is largely due to the benefits mentioned above. PSTN and ISDN are archaic technologies that are slowly being phased out. BT Openreach has confirmed it will stop taking ISDN orders in 2020. If you have ISDN circuits today, and plan on any business growth, ISDN can no longer serve you.

Furthermore, by 2025, all ISDNs will be permanently switched off. Yes, this is still really far away and the date may change. But, you don’t want to be the IT manager that loses sleep because they failed to prepare. The likelihood is that other IT managers will postpone deployment. Come 2025, all the VoIP providers will be inundated with equipment deliveries, porting orders and resource will be a lot lower than today.


Whether you are moving because of the business benefits, the ISDN switch off, or anything else, there are always questions. Here are the most common ones:

How long does number porting take? A straightforward port takes 30 days. Not all porting is straightforward. Depending how you bought and added to your numbers over the years, it could be more complex and takes meticulous planning – but that’s where your service provider takes over.

Can I phase my implementation? Yes. As much as your number porting will allow. If simple, you can move numbers around or install phones and equipment at your leisure. If the porting is complex, you need to be led by what can physically go ahead without causing a break in service.

What is the best VoIP handset? It differs from business to business, depending on requirements. Generally, the leaders in handsets are Polycom, Cisco and Yealink.

What do I need to move to VoIP? You need Internet connectivity. That’s the only pre-requisite you need to take care of before you start your planning. If your connectivity is poor, your VoIP experience will be poor.
