Frequently Asked Questions
What is a cloud business phone system?
A cloud business phone system (also called hosted VoIP) runs your calls over the internet rather than traditional fixed phone lines. Instead of a physical PBX box in your office, the system is hosted in the cloud, so you can make and take calls from a desk phone, mobile, tablet or computer. It’s cheaper to run, easier to scale, and comes with features like call forwarding, video calling and voicemail built in. Our systems use Broadsoft, Microsoft Teams and Webex for reliable, high-quality connectivity.
How much does a business phone system cost?
Cost depends on how many users you have and the features you need, so the pricing is tailored rather than fixed. Cloud phone systems remove the need for expensive on-site hardware, so you’re generally paying a predictable monthly cost per user instead of a large upfront investment. We’ll scope a solution to your team size and call needs – get in touch for a quote.
What's the difference between a cloud phone system and a traditional PBX?
A traditional PBX is a physical hardware installed in your office that routes calls over fixed phone lines. A cloud (or hosted) phone system does the same job over the internet, with no bulky equipment to buy, maintain or replace. That means lower costs, easier scaling as you grow, and the freedom to take calls anywhere. If you’re still on an ageing PBX, we can manage the move to cloud with minimal disruption.
Can I keep my existing phone system?
In many cases, yes. We can usually port your existing business numbers across to your new cloud phone system, so you keep the numbers your customers already know. We’ll confirm what’s possible for your specific numbers as part of setting things up.
Can I take my business calls when I'm out of the office?
Yes – that’s one of the main advantages of a cloud phone system. We can integrate your business phone line with your mobile, tablet or computer, so your calls follow you wherever you have an internet connection. Your team can work from the office, home or on the road using the same number and features.
How many phone lines does my business need?
With a cloud phone system you’re not limited by physical lines the way you were with older systems – capacity scales with your plan. What matters more is how many staff need to make and receive calls at once, and whether you need features like call queues or outbound call centre capabilities. We’ll help you work out the right setup based on how your business actually uses its phones.
Do I need specialist equipment or fast internet?
You’ll need a reliable internet connection, since calls run over the internet, but you don’t need to invest in expensive hardware. You can use existing devices – desk phones, mobiles or laptops – and we’ll advise if any upgrades are worthwhile. If your connection needs a boost, we can help there too through our business internet services.
How do I switch to a business phone system?
It starts with a quick consultation to understand your current setup and what you need. We then design a cloud phone solution, handle the migration (including moving across from an old PBX) and get your team up and running. From there we provide ongoing support so your phones keep working the way they should.
