Quick comparison

All six options offer web, desktop, iOS, and Android access. Pricing details aren’t included here, so check each provider’s current plans and requirements before choosing.

1. RingEX

Best for: Businesses seeking a cloud PBX with access across devices.

RingCentral offers RingEX as a cloud business phone system over VoIP, with mobile and desktop apps for making and managing calls. Its cloud PBX setup means business calling isn’t tied to a traditional desk phone. It may suit teams whose employees take calls from different locations or devices. Check the provider’s details to make sure the features and setup fit your business.

2. Zoom Phone

Best for: Teams that want business calling through compatible devices.

Zoom Phone is a cloud VoIP system that lets teams make business calls through desktop or mobile apps. The app-based access gives employees an alternative to relying on desk phones. Before choosing, check which devices are compatible and whether the service supports your team’s calling needs. Those details can determine whether employees can use it with their usual work setup.

3. GoTo Connect

Best for: Businesses that want phone, messaging, and meetings in one platform.

GoTo Connect combines business phone and softphone features with SMS, meetings, and messaging. The range of communication features is its main distinction. It may suit teams that expect to use more than calling, but a broader platform won’t add much if those extras don’t fit your routines. Compare its features with the tools your employees already use.

4. Vonage Business Communications

Best for: Teams looking to combine calling with other communication channels.

Vonage Business Communications is a cloud-based platform with an app for voice, video, and messaging. Its integrations with business applications may appeal to teams that want communication tools to work alongside their other software. Check whether the available integrations support the applications your team already relies on. A good fit matters more than a long integrations list.

5. Ooma Office

Best for: Small businesses seeking a cloud-based business phone service.

Ooma Office provides cloud-based phone service with features for small businesses. Employees can use desktop and mobile apps for business communications, so app access is part of the everyday setup. Its small-business focus sets it apart. Compare its calling capabilities with the features your team needs regularly. A small-business label doesn’t necessarily mean it covers every workflow.

6. Aircall

Best for: Sales and support teams that rely on CRM or helpdesk tools.

Aircall is a cloud-based phone system for sales and support teams, available through a browser or downloadable app. Its CRM and helpdesk integrations may be useful for teams that manage customer conversations in those tools. Map your current workflows and check whether Aircall’s integrations fit. That helps you judge whether the connections will be useful in practice, not just relevant on paper.
