What is a Cloud Phone System?
VoIP — Your Phone System, Reinvented
A cloud phone system (also called hosted VoIP — Voice over Internet Protocol) routes your business calls over the internet rather than traditional copper phone lines. The PBX hardware that used to sit in your server room? It’s hosted in secure data centres, managed for you 24/7.
Your team makes and receives calls from desk phones, mobile apps, or laptops — from the office, home, or anywhere with an internet connection. You pay a simple monthly licence per user, not per-minute call charges.
No on-site PBX hardware Work from anywhere Scale up or down instantly Fully PSTN switch-off ready

FAQS
Got Questions About Switching to a Cloud Phone System?
We've helped hundreds of businesses across the UK & Ireland make the move. Here are the questions we hear most often.
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.
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.
Most cloud phone systems are priced on a per-user, per-month licence model — typically from £9.98 per user per month depending on the platform and features. This is generally lower than the total cost of ownership for on-premise systems, as 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.
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.
As a general guide, a stable VoIP call requires around 100kbps of bandwidth per concurrent call — well within the range of 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.
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. We also supply business broadband with 4G/5G failover as an add-on, giving you a secondary connection that activates automatically if your primary line drops.
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. Features like auto-attendant also give small businesses a professional call experience previously only available to larger companies.
BT's Public Switched Telephone Network (PSTN) — the traditional copper landline network — is being switched off in the UK by January 2027. All businesses using analogue lines, ISDN connections, or PSTN-dependent systems must migrate to a VoIP or 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.
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. On-premise systems offer more control and suit businesses with specific compliance or connectivity requirements.
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, no third-party contractors.
