What is a cloud phone system?

A cloud phone system (also called hosted VoIP) routes your business calls over the internet rather than traditional phone lines. The system infrastructure is hosted in secure data centres, meaning you don't need on-site PBX hardware. You pay per user licence, calls are made via desk phones, mobile apps or softphones, and management is handled remotely — making cloud systems more flexible and cost-effective than traditional setups.

What is VoIP and how does it work?

VoIP stands for Voice over Internet Protocol. It converts your voice into digital data and transmits it over your internet connection, rather than traditional copper phone lines. Calls can be made from desk phones, computers, or mobile apps. For businesses, VoIP offers significant cost savings, greater flexibility, and a much wider range of features than analogue or ISDN lines.

How much does a cloud phone system cost?

Most cloud phone systems are priced on a per-user, per-month licence model — typically from £12 per user per month depending on the platform and features. There are no large upfront hardware costs and maintenance is handled remotely. Yellowcom provides bespoke quotes based on your user count, call volumes, and requirements.

Can I keep my existing phone number when switching to VoIP?

Yes. Yellowcom handles full number porting as part of every installation. Your existing geographic or non-geographic numbers are transferred to your new cloud system with zero disruption to incoming calls. The porting process is managed entirely by our team.

What broadband speed do I need for a cloud phone system?

A stable VoIP call requires around 100kbps of bandwidth per concurrent call — well within most business broadband connections. More important than raw speed is connection quality; low latency and minimal packet loss are critical for clear calls. Yellowcom includes a full VoIP connectivity assessment with every installation.

What happens to my phones if the internet goes down?

Modern cloud phone systems include built-in failover options. With iPECS Cloud, calls can be automatically diverted to mobile numbers or an alternative site if your main connection fails. Yellowcom also supplies business broadband with 4G/5G failover as an add-on, giving you a secondary connection that activates automatically.

Is a cloud phone system suitable for small businesses?

Absolutely. Cloud phone systems are particularly well-suited to small businesses — no large upfront costs, no hardware to maintain, and you only pay for the users you need. Systems like iPECS Cloud can start with as few as 2 users and scale as you grow.

What is the PSTN switch-off and how does it affect my business?

BT's Public Switched Telephone Network (PSTN) is being switched off in the UK by January 2027. All businesses using analogue lines or ISDN must migrate to VoIP or a cloud-based alternative before the deadline. In Ireland, a similar copper network migration is planned under ComReg's roadmap. Yellowcom manages the full transition for you.

What is the difference between cloud and on-premise phone systems?

With a cloud phone system, all infrastructure is hosted in data centres — you simply connect your phones via the internet. With an on-premise system, a PBX unit is physically installed on your site. Cloud systems require lower upfront investment, are easier to scale, and are maintained remotely.

Does Yellowcom cover the whole of the UK and Ireland?

Yes. Yellowcom supplies and supports cloud phone systems across Northern Ireland, Scotland, England, Wales, and the Republic of Ireland. We have offices in Belfast, Glasgow, and Dublin, with local engineers available for on-site installations and support — no offshore call centres.

“We were still on ISDN with no idea what to do before the switch-off. Yellowcom sorted everything — new system, ported our numbers, trained the staff. Couldn’t recommend them more.”

“Having local engineers available makes a huge difference. When we had a question after going live, someone picked up the phone — not a chatbot, not a call centre queue.”
