Smarter, Cheaper, and More Flexible Communication

In today’s fast-paced, digitally connected world, traditional telephone lines just don’t cut it anymore. Whether you’re a small startup, a growing mid-sized business, or a large enterprise, switching to a VoIP (Voice over Internet Protocol) phone system can revolutionise how you communicate.

At 5G Communications, we specialise in providing reliable, scalable, and cost-effective VoIP telephone systems tailored to your specific business needs.

What is a VoIP Phone System?

VoIP stands for Voice over Internet Protocol. Instead of relying on traditional copper wires or analogue telephone lines, VoIP technology transmits your voice calls over the internet. It converts your voice into digital signals and sends them through your broadband connection.

This means you no longer need to depend on outdated landline infrastructure or pay extra for long-distance and international calls. With VoIP, everything is unified through your internet service—giving you flexibility, mobility, and enhanced features at a fraction of the cost.

Key Benefits of VoIP for Your Business

1. Cost Savings

One of the most compelling reasons businesses switch to VoIP is the significant reduction in costs. Local and international calls are much cheaper, and you can eliminate the cost of maintaining separate voice and data networks.

2. Advanced Call Features

VoIP systems come packed with features you’d normally only expect from high-end PBX systems. These include:

  • Call forwarding and routing
  • Voicemail-to-email
  • Call recording
  • Auto-attendants (IVR)
  • Hold music
  • Conference calling
  • Caller ID, call queuing, and more

3. Flexibility and Mobility

With VoIP, your telephone system moves with you. Staff can make and receive calls from anywhere using a desk phone, mobile app, or desktop softphone—ideal for remote or hybrid workforces.

4. Scalability

Growing business? No problem. Adding a new user or line is as simple as clicking a button. There’s no need for new phone lines or expensive hardware installations.

5. Business Continuity

VoIP systems are hosted in the cloud, which means your communications remain operational—even during power cuts or natural disasters—so long as you have internet access or mobile data.

Who Can Benefit from VoIP?

VoIP telephone systems are ideal for:

  • Startups and SMEs looking for low-cost, professional telephony
  • Remote teams and hybrid businesses needing seamless communication
  • Call centres and customer service teams requiring advanced features and analytics
  • Multi-location companies who want a unified system across sites

FAQ’s

VoIP (it stands for Voice over Internet Protocol) means that you make calls over the internet rather than over the traditional phone network. And with a cloud-based phone option, your call routing takes place in our internet-connected secure data centre instead of in hardware installed on your premises.

Put these technologies together and you get a cloud-based VoIP system. Why would you want one? How about lower upfront costs, fixed monthly pricing, no maintenance, and automatic updates for starters? Plus, being on the internet means you can manage your service through an online portal wherever you can get an internet connection; and the service easily grows as your business does.

Yes, you’ll get the same level of clarity as you do with a regular landline (depending on the set-up and the internet connection, call quality may even be better). Calls made over your internet connection take priority over data, so you can be sure that your call quality will be consistent.

When you talk to us about installing a cloud-based phone service, we’ll discuss your current broadband connection to ensure your VoIP calls will be of good enough quality for your business. And if you’re looking for a new broadband connection, we’ll find the right package for your business from our comprehensive range: standard broadband, fibre broadband, or SoGEA.

This phone system allows your business to have access to similar features that a larger company would without the high costs associated with the purchase of on-premises PBX equipment

Our VoIP phone service is designed to scale it suits all sizes of business whether you have a single home office or multiple locations around the globe. With on-demand features and same-day provisioning you can add users or remove users quickly and easily.

With our advanced feature packs you can completely tailor the user’s experience and provide a call centre solution, reception console and much more with a simple click.

Call us on 01494 523 523 to receive pricing and specialist advice on our IP phone ser options.

We aim to make setting up as simple as possible, which is why you’ll have a team of cloud experts to call on if you need help.

Our 5G Cloud Phone service is the simple plug and play option where phones arrive ready to go. Just connect things together and we’ll talk you through how to set it up so it’s right for your business, including help with setting up call handling rules and user profiles.

The 5G Cloud Phone service, which is ideal for the business with more than 9 employees, is also a system that you can install yourself, but you’ve also got the option for us to pop in and set it up if you prefer.

How much you’ll pay depends on several different factors so it’s difficult to give you a price just here.

It all depends on which service is best for your business: how many people will be using the system, now and in the future? How does your business work? How many IP phones do you want? What type? What about Feature Packs and call minutes? And so on …

So give us a call and we’ll have a chat about what you need.

For starters, everything you need you can get directly from us, making the whole process easy. All the equipment and the internet connections we supply are designed to work together to give you the highest quality of service.

To get you up and running, you’ll have support from our team of VoIP experts who will help you set up the system so it works for how you run your business. They’ll show you how to configure and manage it through the online portal.

And you’ll be able to call our free helpdesk for technical help or advice, whenever you want.

The speed you need basically depends on a couple of things: how many people will be on the phone at the same time; and how much data your business uses.

You might think you need fibre broadband, but this isn’t necessarily the case as a VoIP call only uses a fraction of your broadband’s capacity.

Don’t worry about this, though. We won’t place any orders until we’ve talked to you about how your business works, what you want to achieve, what your future plans are, and so on.

We host our cloud-based service across multiple secure data centres, each in a different location. In the unlikely event that one of them has a problem, another takes over. Our business broadband and fibre broadband networks are very reliable.

But let’s say your internet connection does have an off day. You can take your IP phones, plug them into another broadband service and carry on as normal, using the same number (note, though that, we’ll only support your cloud-based phone system when you’re using it with the 5G Comms Business equipment and internet connection that we set it up to work with).

And, when things are up and running again, re-connect your phones as before and you’re back in business with high quality phone calls. Or, using the online portal, you could just re-direct your calls to any other landline or mobile.

There are several ways you can use your mobile.

You can set your mobile to ring whenever your office phone does, which is handy whether you’ve just popped away from your desk or you’re out of the office.

With 5G VoIP Phone Systems you can flip calls between phones. So if you get a call on your Cloud Voice number, say, just as you’re leaving the office to go home, you can flip the call seamlessly from the office phone onto your mobile.

And then there’s the mobile app (for Android and iOS devices).

This turns your mobile into an extension of your phone system. Not only can you answer and make calls, but you’ll also be able to see when people are available to talk, set-up call routing, and transfer calls between colleagues.

With the mobile app you can control your phone system from wherever you are.

Yes.

Security is absolutely crucial.

That’s why the data centres where we host our VoIP phone services undergo robust audits; it’s why they have everything from firewalls to intrusion detection systems; and it’s why all your data is encrypted, to protect it from cyber-attacks and unauthorised access.

First, you’ll need an internet connection and the equipment that comes with it. If you’re looking for a new broadband connection, we can find the right package for your business from our comprehensive range: standard broadband, fibre broadband, or leased line.

Next, you’ll need IP phones from 5G Communications or use exisiting (note: our VoIP service will only work with our IP phones, which are specially designed to work with our cloud-based VoIP service. We also pre-configure our IP phones before we deliver them to you). If you want to make calls through your computer, you’ll need a headset and microphone that plugs into your computer.

You’ll also need appropriate Feature Packs for each user. The packs offer different levels of features.

If you’re ordering lots of phones, you may need a Local Area Network (LAN), which connects all of them together into one phone service. We can supply and install one for you.

And if you want to use a standard phone or even a fax machine on your system, we can supply an Analogue Terminal Adapter that connects to your Business Hub or LAN. You can then just plug your standard phone in and use as normal.
