RingCentral: Best UCaaS provider overall
Why I chose RingCentral
I chose RingCentral as the best UCaaS provider overall because it offers the strongest combination of business calling, video meetings, team messaging, AI assistance, administration, and integrations. Businesses can consolidate phone, text, fax, chat, and video communications into a single cloud-based platform while connecting RingCentral to more than 500 business applications.
RingCentral is especially well suited to growing, distributed, and multi-location organizations that need advanced call routing, multi-level IVR, call queues, monitoring, analytics, and centralized administration. Reviews often note that it requires more setup and management than simpler business phone systems, but that additional depth gives organizations more flexibility as their communication needs become more complex.

Nextiva is also best for businesses that want UCaaS to support sales, service, and customer experience rather than just internal collaboration. Smaller teams can use its core calling and routing tools, while larger teams can expand into more advanced customer engagement and analytics features.

Ooma: Best for easy DIY setup
Why I chose Ooma
Ooma is my pick for an easy DIY setup because it gives small businesses a straightforward way to launch cloud calling, virtual receptionist tools, extensions, and mobile access without a complicated deployment process. It is a practical option for offices and small teams that want reliable business phone service without a heavy administrative lift.
With that said, Ooma is less advanced than RingCentral, 8×8, or Dialpad, but that simplicity is part of its value. It works best for teams that primarily need voice, texting, voicemail, basic routing, and office-friendly phone features rather than a full enterprise communications suite.

Organizations already using Zoom can add cloud phone service while keeping calls, meetings, team chat, contacts, and administration within the same platform.
Zoom Phone is particularly useful for video-first and hybrid organizations that want employees to move easily between phone calls and Zoom meetings. Businesses can purchase phone service separately or choose a Zoom Workplace + Phone bundle. However, a phone-only plan does not automatically include all the capabilities of a paid Zoom Workplace subscription.

8×8: Best for international calls
Why I chose 8×8
I chose 8×8 for international calls because it is built for organizations that need global communication across voice, video, messaging, and contact center workflows. It is especially useful for businesses with international teams, customers, or offices that need more than a domestic VoIP plan.
8×8 is also a strong option for teams that want a UCaaS platform with a contact center upgrade path. It may take more effort to configure than simpler systems, but its depth in global calling, security, analytics, and communications makes it a strong fit for companies with complex international needs.

Pricing
8×8 does not publish standard US pricing for 8×8 Work. Businesses must request a custom quote based on their number of users, locations, calling requirements, and selected capabilities.
Organizations can mix and match licenses and services across:
- 8×8 Work: Unified calling, meetings, messaging, and collaboration

Dialpad: Best for AI-powered communication

Dialpad is my pick for AI-powered communication because it integrates AI directly into its calling, messaging, meeting, and voicemail workflows. It is a strong option for teams that want real-time transcription, voicemail summaries, call summaries, action items, and post-call insights without relying on separate AI tools.
Dialpad is especially useful for remote, hybrid, and customer-facing teams that want searchable conversation records and faster follow-up. Its entry-level plan offers a strong collection of AI and communication features for small teams, while Pro adds CRM integrations, 24/7 support, and multi-office management. However, businesses primarily focused on large video events or complex contact center operations may need additional Dialpad products.

More about VoIP
How do I choose the best UCaaS provider for my business?
The best place to start is assessing your current communication tools and processes. Along the way, you’ll be able to identify gaps or pain points, like poor call quality, high operational costs, or inadequate security features. From there, you can look for a UCaaS solution that addresses these issues and offers scalability for future growth.
After you’ve shortlisted a handful of providers, check reviews to evaluate reliability, customer support, and integration capabilities with your existing tools.
A free trial can also be invaluable for testing usability and ensuring the platform meets your expectations.
Beyond that, a personalized demo can give you a good idea of what the solution looks like in action and allow you to ask as many questions as you need to determine whether it’s the right fit.
Methodology
I relied heavily on my personal experience in the business communications category, as well as a large body of publicly available reviews, case studies, and other online resources to support my own experiences.
Overall, my goal was to gather relevant information on each provider’s real-world performance, customer satisfaction, and overall quality.
Here’s a closer look at what I considered when putting this guide together.
- Features, functionality, and capabilities: The breadth and quality of features offered by each UCaaS solution were crucial. I specifically sought providers that offer comprehensive toolsets to meet a wide range of communication needs.
- Ease and depth of integration: I carefully considered the quality, depth, and execution of each provider’s integrations with other business tools. Simply having a large list of integrations isn’t enough. Strong connections with CRM, ERP, and collaboration tools were the bare minimum for inclusion in this post.
- Pricing structure: To include a range of tools for businesses of different sizes, I chose platforms that span the price spectrum.
- System reliability: Dependable service with minimal downtime is huge for any business. I favored providers with a strong track record of reliability and uptime.
- Security and compliance: The best UCaaS provider gives you peace of mind. As such, I prioritized providers that demonstrate a strong commitment to security and regulatory compliance.
- Customer support: Access to responsive, helpful customer support was a minimum requirement for inclusion on my list, as it’s vital that businesses can get assistance when they need it.
