Business Telecoms FAQs

Got a business telecoms question you've always wanted answered?

Send us your question and we'll answer it for you!

What is the best telecoms solution for SME businesses?

We’ve found that for business with a decent volume of inbound and outbound calls, a flexible VOIP platform like 3CX can do almost anything they need, from contact centre features to API integration.

If you already use Microsoft 365 in your business we can help you extend that functionality into external dialling, which may mean you can ditch your separate phone system. We can even ensure you can keep your numbers.

We’d also advise treating your mobiles and telecoms system as one – they’re all used for customer contact at the end of the day! We can help you bring everything together into a single service.

How can I reduce telecoms costs for my business?

How much you can reduce your costs by really depends on what your current setup is. We’re experts across all areas of telecoms, and we love saving customers money.

Book yourself an initial consultation with us and within 15 minutes we’ll be able to tell you if we’re able to save you money.

In the majority of cases we are able to save money and add features and security at the same time!

How long does it take to set up a new telecoms system?

That depends on the complexity of the setup and what’s needed “on the ground” in any physical locations you may have. However, in the past we’ve even been able to get people up and running on the same day! That’s because 3CX, our preferred system, can be hosted in the cloud, has app and web-based calling, and unlimited extensions are available at no extra cost.

But the best thing to do if you need a solution quickly is book an initial consultation with us – we’ll soon be able to tell you what’s what..

What are the best business mobile plans in the UK?

The best business mobile plans are the ones that improve your business.

Sorry if you were hoping we’d tell you a specific provider and plan, but in our experience, the cheapest is rarely the best.

There are so many things that business should consider when it comes to the mobility of their business – from cost and coverage through to security and resilience – it really is best to have an open conversation with experts like us.

Not only can we help you decide on the approach – and providers and plans – that are best for your business, we can help you with ongoing management, plus, you’ll have a single bill from us, making the billing side waaaaaay simpler!
