Top 10 unified communications providers for your business [2025]

Zoom’s unified communications and collaboration solutions offer everything you need to keep your team and customers connected. Zoom Workplace provides a one-stop shop for calling, messaging, meetings, and more, available across desktop and mobile devices. 

Plus, with advanced AI features included at no additional cost with eligible paid plans, you can get assistance when you need help with note-taking, writing a message, or brainstorming ideas. Let’s dive into what makes Zoom Workplace a standout unified communications solution:

• AI Companion: Zoom AI Companion is like having a smart assistant built into your workflow. It helps you stay on top of meetings by generating agendas, real-time summaries, and follow-up action items. You can also use it to brainstorm ideas, draft messages, and even get help organizing your to-do list — all without switching tabs or slowing down.
• Cloud VoIP phone system: Zoom Phone gives you the flexibility to make and receive calls from any device. You can also elevate calls to video with a click.
• Simplified video conferencing with Zoom Rooms: Zoom Workplace was built for video, and with Zoom Rooms, unified communications video conferencing is easier than ever for in-office environments. You’ll have simple booking options, one-touch meeting starts, and wireless content sharing from connected conference rooms.
• Advanced collaboration tools: Zoom Workplace makes teamwork easier with built-in tools like whiteboards, docs, and the ability to jump from a chat to a call or video in seconds. As an open platform, Zoom also supports over 2,500 integrations through the Zoom App Marketplace — so you can bring your favorite business apps right into your workflow.
• Customizable scaling: Zoom Workplace makes it easy to scale your communications setup as your team grows. Admins can quickly provision new users, configure policies, manage licenses, and roll out features across teams — all from an intuitive admin portal. Whether you're onboarding ten employees or a thousand, Zoom Workplace puts admins in the driver’s seat — without the usual IT headaches.

RingCentral is a unified communications solution that provides a cloud-based phone, video, and messaging system, which works especially well across distributed or remote teams. With a mobile app, users can access communications from anywhere that has internet access. It’s also easy to integrate with many commonly used business apps, like Google Workspace and Microsoft 365. 

However, some users report that advanced features can be tricky to set up, and while there are options at a lower price point, they come with limited features.

Vonage offers Voice over Internet Protocol (VoIP) solutions that users can customize to meet specific business needs. They also integrate with CRM tools and other business software, keeping companies connected to their customers. The ability to customize service also makes it easy to scale as business grows.

Users report, however, that the interface isn’t as intuitive as some other solutions. Setup can be challenging, too — especially for small businesses that may not have extensive IT resources. And while it’s reasonably affordable, some features are only available with an additional subscription fee.

Gamma Horizon, often referred to as just Horizon, offers an affordable communication solution that covers the essentials. It’s a cost-effective option with flexible pricing models and an easy-to-use interface. As a cloud-based platform, it’s simple to scale without the need for complex IT infrastructure.

While Horizon is a budget-friendly choice, it’s not a full-fledged unified communications platform. It lacks some of the advanced features offered by other tools, particularly when it comes to messaging and third-party integrations. For video conferencing, Horizon relies on an integration with Webex, and it doesn’t provide a complete suite of UC tools like chat or extensive customization options.

Microsoft Teams is a well-known UCaaS solution that’s deeply integrated with Microsoft 365, making it a strong contender for companies already set up on Microsoft products. Teams offers plenty of internal communication and team collaboration tools like file sharing and editing, in addition to chat and video features. 

But because there are so many features and settings, users may be overwhelmed or have more than they truly need. And even with extensive features, Teams has limited video conferencing abilities compared to dedicated video platforms. Some users also find that Teams runs slowly at times, especially when trying to manage large meetings.

8x8 is a scalable UCaaS solution provider that can fit the needs of small businesses and large enterprises alike. It offers VoIP calling, video conferencing, and team messaging and provides reporting and analytics tools to help track communications. Users report that the customer service and support are accessible and helpful. 

Users also note that the interface is less intuitive than some other systems, and call quality can vary based on network performance. While the price point is reasonable, some advanced features only come with higher-tier, higher-cost plans.

Dialpad provides AI-driven features for call transcription, sentiment analysis, and other call analytics. It also has a mobile app that’s useful for communicating on the go. Customers find the user interface easy to use and simple to set up. 

While Dialpad comes at a reasonable price point, some features, like more advanced reporting, are only available at a higher tier. Additionally, the video conferencing features are lacking compared to similar products.

GoTo provides VoIP, video conferencing, and team messaging while offering tools to streamline operations. For example, auto-dialer features make it easier to make a high volume of calls, and agent training tools help level up the team. Users find GoTo simple to set up and learn, and they appreciate the customization options. 

However, some users say GoTo comes at a higher price point than similar tools, and it’s lacking some of the more advanced collaboration features offered by other solutions.

Cisco’s Webex provides AI-powered video conferencing features, which work well for large meetings or webinars. It’s a popular platform that integrates with many frequently used business apps, and its enterprise focus means there are strong security features. 

It may not be a fit for smaller businesses, though, especially if they lack IT support, as setup can be complex. Some users find the interface less intuitive than other tools, and higher-tier plans can be costly.

Avaya offers standard UCaaS features like video calls and live chat, and its focus on live customer engagement makes it a good fit for contact centers or other customer-facing businesses. Users can customize it to their needs, and reviews note reliable call quality and service.

However, users also note that the interface is a bit outdated and the system can be challenging to set up and integrate with other systems. Pricing is also less competitive than some other options.
