What is cloud telephony and how does it work?
What is a cloud-based phone system?
A cloud telephony definition.
A cloud-based phone system known commonly as cloud telephony, hosted telephony or VoIP - is a modern communication solution which operates over the internet rather than traditional phone lines. Forget about the limitations of on-premises hardware. This technology enables businesses to make and receive calls through a VoIP service, which delivers notable flexibility and scalability.
Cloud-based telephony solutions integrate seamlessly with other communication tools, making it ideal when you seek an efficient, reliable, and cost-effective communications platform.
How does a cloud-based phone system work?
Examining the functionality behind a cloud telephony system.
Cloud-based phone systems utilise VoIP technology to transmit voice data over the internet. When a call is made, analogue voice signals are turned into digital data packets. These packets then travel through the internet to the recipient’s device, where they are reassembled into voice signals.
A cloud telephony platform system operates through cloud servers – hence the name – which are managed by service providers. This delivers high availability and redundancy. Additionally, the flexible system can be accessed via various devices, including desk phones, smartphones, and desktops.
Standard features of a Cloud Phone System
Any time, anywhere
Your cloud telephony licences can be live on multiple devices, meaning your teams can answer calls from their mobile, desktop or desk phone. They can choose whether each device rings depending on what they are using, so they can be available any time, anywhere and on any device.
Call forwarding
Redirect incoming calls to another number or device. This prevents important calls from being left unanswered, no matter where you’re located.
Voicemail to email
Receive voicemail messages directly in your email. This allows for easy access, management, and archiving, a feature that ensures you never miss important messages – even when away from your phone.
Auto attendant
A cloud-based telephony system can automatically answer calls and direct them to the appropriate department or extension. This efficient, accurate call routing boosts customer service.
Scalability
Cloud telephony solutions allow you to easily add or remove features as your business needs change. This flexibility means your phone system can grow alongside your business without significant investment.
Mobile integration
The phone system is accessible through mobile apps, enabling communication on the go. This supports remote work and keeps employees always connected.
Conference calling
Facilitate virtual meetings with multiple participants seamlessly. This feature is essential for remote teams, where it promotes collaboration and efficient communication.
Benefits of a cloud phone system
A wealth of business advantages.
A cloud telephone system offers numerous benefits. One of the most notable is cost savings. Cloud systems eliminate the need for expensive on-site hardware, which doubles by reducing maintenance costs. Flexibility, in terms of scalability, allows your business to easily adjust its communication infrastructure as it grows.
Cloud telephony systems support remote work by allowing employees to connect anytime, anywhere and on any device. Add in advanced features that range from CRM integration to contact centre solutions and it can improve all aspects of your company’s efficiency and customer service.

Cloud Telephony vs VoIP
How these communication technologies differ.
It’s true: cloud telephony and VoIP are closely related – but they’re not identical. VoIP refers to the technology which enables voice communication over the internet. Cloud telephony, on the other hand, encompasses a broader range of internet-based communication services, including VoIP.
Beyond VoIP, cloud telephony services offer additional features like call routing, voicemail, and integration with other business tools. VoIP is a key component of cloud telephony, but the latter delivers a comprehensive communication solution designed specifically for your business needs.
