Why to choose VoIP for businesses



VoIP (or Voice over Internet Protocol) is simply just the method of transmitting voice communications (telephone calls) over an IP network such as an office Local Area Network (LAN) or the Internet. It is also the latest evolution of communications technology that includes ISDN and, as you’d expect, there’s a lot of debate as to which is better.

The following guide details why VoIP is fast becoming the communications technology of choice for today’s businesses:

Reduce Costs

VoIP provides many benefits over legacy telecoms technologies but by far the most documented will be in terms of costs. Substantial savings should be realised in terms of the rental costs and ongoing call charges but you will also find that VoIP deployments are easier to manage so there would be additional cost savings in terms of engineering and support charges.

Enhanced Functionality

The ability to have remote extensions such as home-workers, retain you landline number and deliver faxes to your inbox are just some of the additional features VoIP can introduce to a business over the legacy telecommunications options.


In the old days of digital telephony you would have to have paid for an engineer to come and move an extension, thus making reorganising an office an expensive and complex project. With VoIP, you simply unplug the phone at the old desk and then plug it in at the new desk and the ‘system’ will take care of the configuration.


Disaster recovery comes as standard with VoIP. Unlike ISDN, in the event of a disaster such as a fire or flood, you would be able to log onto a portal and re-route where your inbound call traffic would go so that you can continue to operate. With ISDN this would be a time-consuming and costly exercise.

Future proofed

Sweden has already stopped delivering legacy ISDN services and it’s widely expected that the UK will follow suit in a few short years. By deploying VoIP today you are future-proofing your telecommunications and enjoying the additional benefits VoIP brings.


Easy to migrate

Making the switch to VoIP is incredibly simple. Firstly, everything happens remotely so you don’t have to do anything. Then, you can migrate in phases with no disruption to your existing services. And whilst VoIP is secure, reliable and resilient you can also retain some of your legacy services as a back-up for complete peace of mind.

You’re already using it…

Interestingly, you’re already using VoIP, even if you’re using ISDN. BT’s 21st  Century Network (21CN) project migrated their core network from legacy PSTN technologies to the latest carrier grade VoIP which means that once your call reaches the BT exchange it will be carried over their new VoIP network.


As VoIP is much more flexible than traditional technology it’s easier to build in security features that would be too costly or just impossible with legacy solutions which means that for sensitive information such as financial details remain safe and secure and cannot be eavesdropped.
