Full PBX features delivered over the internet — no on-site equipment required
Works on any device from any location — perfect for hybrid and remote teams
Scale users instantly — add new team members in minutes, not weeks

A cloud phone system (also called hosted PBX or cloud telephony) delivers all the features of a traditional business phone system over the internet — without any on-site hardware to maintain. Call queuing, auto-attendant, hunt groups, call recording, voicemail to email, and CRM integration are all available as standard. Users make and receive calls on desk phones, computers, or smartphones — from any location with an internet connection.
Cloud phone systems eliminate the capital cost and maintenance burden of physical PBX hardware. They enable hybrid and remote working — your team can use their business phone number from any device, anywhere. They scale instantly as your team grows. And with the ISDN switch-off in January 2027, migrating to a cloud system is no longer optional for businesses still on traditional phone lines.

Key questions for businesses comparing cloud phone system options.
Cloud phone systems and VoIP are closely related — both deliver calls over the internet. VoIP is the underlying technology; a cloud phone system is the complete service package including the management platform, features, and support. All cloud phone systems use VoIP, but not all VoIP services include the full-featured management platform of a cloud phone system.
Yes — if your current phone system uses ISDN or PSTN lines, it will stop working after January 2027. Now is the ideal time to migrate to a cloud phone system, take advantage of improved features, and avoid any last-minute scramble before the deadline.
Yes — most cloud phone systems integrate with Salesforce, HubSpot, Microsoft Dynamics, Zoho, and other major CRMs. Calls are logged automatically, customer records surface when a call comes in, and outbound dialling can be initiated directly from the CRM.
Cloud phone systems can often be set up and operational within 1–5 days. Number porting (transferring your existing numbers) typically takes 5–10 working days. Your provider will manage the process and ensure continuity of service throughout.
