The best cloud phone systems provide an easy to use and manage business PBX (Private Branch Exchange) system in the cloud, allowing even small businesses access to phone features normally only affordable for enterprises.

Cloud phone systems are now increasingly replacing old hardware due to their cost-effectiveness. As cloud-based phone systems run through software and use VoIP for calls and communications, they can offer much more versatile performance while including a rich range of features as standard, such as analytics and integrations. 

Better still, pricing works out as much more efficient as you are paying for what you use, rather than having to invest in expensive on-premises hardware. This means that even small businesses can now access full-featured VoIP services for the office and even the home, which include features previously only enterprise companies could afford to build.

The result is that a small business can have a cloud-based phone system that also provides Unified Communications as a Service (UCaaS), for keeping all messaging, calls, and video conferencing, all working from the same platform. 

On top of this, small businesses can even use cloud-based call centers by utilizing Contact Center as a Service (CCaaS) provisions which are sometimes built into existing cloud-based phone systems.

Overall, cloud services have been transforming and revolutionizing the telecoms industry and the range of services that can be provided and made accessible. Here we'll feature the best in cloud phone systems.

2. Ooma Office

Affordable cloud phone services

Reasons to buy
+Easy to set up+Great value+Virtual receptionist
Reasons to avoid
-Mobile apps have some flaws

Ooma Office is a cloud-based phone service which aims to deliver a big business phone experience to small businesses.

Ooma might not be overflowing with the kind of bells and whistles you might find with some VoIP services, but it presents itself as a solution for smaller firms with tighter budgets, and is positioned very well in this respect.

However, don’t get the idea that this is a barebones VoIP offering – in fact Ooma Office gives you all the core features you would expect, plus some more advanced functions like a virtual receptionist that allows for calls to be automatically directed to the right department.

Subscribers also benefit from hold and transfer music, and Ooma provides mobile apps for iOS and Android, so you can set up capabilities such as call forwarding, enabling calls to be sent from your desk phone to your mobile when you’re out and about. That said, some of the online feedback about the mobile apps isn’t great, so bear that in mind.

Generally speaking, though, Ooma gives you a lot of functionality for a relatively modest outlay. There’s no fuss – you get all the features with that one subscription plan – and what’s more the system is easy to set up and get going with.

Naturally, you don’t get everything compared to the feature-sets of the more costly rivals out there, and the most notable missing piece of the puzzle is a lack of CRM integrations.

And, as expected, there's an analytics suite to help gauge efficiency and track KPIs in workflows and look for ways to improve them.

Because of this, Aircall also provides a large number of integrations, not least SalesForce, Zendesk, Hubspot, Zoho, Freshdesk, and Slack. However, note that a minimum of three users is required to operate this service.

Overall, though, Aircall provides excellent functionality with a low cost cloud phone system that's easy to use and accessible for small businesses as well as enterprises.
