VoIP Systems

Voice over Internet Protocol (VoIP) is a phone system that transmits your voice over the Internet. It’s also known as IP telephony, internet telephony or internet calling. In contrast to a public switched telephone network (PTSN), VoIP allows you to make phone calls without the use of phonelines. It’s quickly becoming the default means of communication for modern businesses, replacing the once-standard analogue phonelines.


VoIP is a hassle-free, low-cost option suitable for many different types of business. It grants you flexibility, helping enable remote working and letting you manage everything through a computer app. VoIP also has the benefit of lower call charges, as well as reduced outlay on multiple phone lines or lots of hardware.

How does VoIP work?

Unlike a traditional analogue telephone call, VoIP transmits your voice digitally. VoIP converts audio into packets of data that are converted back into audio at the other end of the line. This compressing and unpacking is handled by something called a ‘codec’, a hardware or software process that changes audio signals into data – and back again.


These data packets go from A to B through an internet protocol (IP), either via a Local Area Network (LAN) or online. Delivery is instant: the person you are speaking to experiences a phone call just as they would with the traditional method.


You can use software or hardware options to make VoIP calls. With hardware, you use a traditional handset and you’d be hard-pressed to see the difference between VoIP and analogue telephone calls.


The other option is using a software-based VoIP phones, often referred to as ‘softphones’. These are applications installed on a mobile phone or computer, and many of them have interfaces resembling a classic phone handset. You can use the computer’s built-in microphone and speakers to make calls or opt for a headset to boost your audio quality. Softphone providers include CloudTalk, GoTo Connect and LiveAgent. 


Why upgrade to VoIP?

We’ve focused a lot on the similarities between VoIP calls and traditional ones, so you may be wondering: what are the benefits?


The major one is cost. VoIP means you don’t have to invest in expensive private branch exchange (PBX) hardware, new phone lines and extra wiring. One Ethernet connection is sufficient for physical VoIP phones, while softphones are unlikely to need any additional connection. Businesses will also save on international calls, since going through the internet sidesteps the premium rates that have long bedevilled global companies. Another money-saver is that repairs for VoIP systems are cheap – there is simply less hardware involved, and it tends to be newer and more reliable than traditional telephony.


An additional benefit is the inherent flexibility that VoIP phone systems offer. This is a boon to companies seeking to be as accessible and agile as they can. A cloud phone system, for example, will let users make and receive business calls from anywhere they can access an internet connection. A handy perk is that the phone number will remain unchanged, helping your business present a professional image. In an age where remote and hybrid working are the norm, this consistency can make a big difference to the smooth running of a firm.


Finally, businesses with a VoIP system will have an easier time scaling. Because VoIP works through a network, adding another user is as simple as setting them up with a laptop or a handset. A fast-growing company can save themselves a hardware headache by investing in VoIP.

Case Study: How VoIP enabled growth for an asset finance firm

A major player in the asset finance sector called upon Espria to upgrade their communications infrastructure. They needed a flexible and future-proof solution that would let them communicate across multiple locations and keep pace with their business’s rapid growth. Their current on-premises solutions couldn’t meet these needs. Out-of-date handsets lacked the ability to transfer calls, making it impossible for the business to consistently meet the high standards they aspired to.


Our solution was to implement a cloud-based VoIP with unified communications. We teamed up with iPECs cloud to set up a cutting-edge system that would allow our client to work in ‘hunt groups’ – a feature allowing a user to distribute calls from one number to many numbers – across their multiple sites. The unified communications element of our approach granted our client a newfound flexibility, with staff now able to make calls with their office numbers from any location. Additionally, field staff could seamlessly collaborate by leveraging file sharing, conference voice, video call and instant messaging capabilities.


Our client wanted to retain traditional handsets, so we set them up with the LIP-9030. A flexible directory helped handle high volume, and the business also saw big efficiency gains from the use of hunt groups to turn what would have been multiple calls into just one.


Here’s what Tom, the co-owner, said:


“As a young, progressive and ambitious growing company, we needed to ensure we aligned ourselves with a communication system that not only supported our current growth but also supported us in the future and we feel the iPECs system does that.”

How to switch to VoIP

The first step is contacting a trustworthy provider. They will be able to explain the rest of the process, give you a quote and help you manage the transition should you choose to switch.


You can choose between a hosted VoIP service (also known as cloud-based VoIP) or a physical service running off hardware on your business’s premises. Cloud-based services come with a monthly fee. Hosted VoIP is the best option for most businesses as it’s low maintenance and straightforward to set up.

VoIP/ IP Phones


Hosted VoIP is another named for cloud-based VoIP. It means that the service is delivered remotely via the cloud rather than through a server located on the business’s premises.

VoIP software comes many forms, each of them specialised to a different set of needs. Some offer video conference, business texting and even integrated email marketing, while others are more basic. Examples include 4Com, Lily Comms, Vonage, Berry, CloudTalk, GoTo Connect, LiveAgent and iPECs Cloud.

The simple answer is yes. VoIP systems incur lower costs (especially at scale) and come with a raft of advantages that landline simply cannot compete with. These include the capacity for video conferencing, calling from an office number from anywhere and the ability to quickly add large amounts of users.

Yes, Zoom provides a VoIP system. Their Zoom Phone solution integrates with the well-known Zoom video conference software to replace traditional landline services.

You need a reliable internet connection to take full advantage of VoIP – otherwise calls can be prone to poor audio quality and lag. VoIP also lacks the location tracking capability that emergency services providers often utilise when responding to accidents.
