For Colorado businesses, where weather disruptions and distributed teams are common, Intermedia offers the kind of resilience and real-world functionality that truly stands apart.

2. RingCentral MVP (now RingEX) – The Industry Giant with a Proven Track Record

RingCentral continues to be a leading name in UCaaS—and for good reason. Its robust feature set, enterprise-level security, and reliable performance make it a solid choice for medium to large businesses.

What makes RingCentral a top contender:

• Cloud PBX, SMS, MMS, fax, and team messaging in one app

• Excellent analytics and real-time reporting tools

• Strong integrations with CRMs and productivity apps

• Scalable pricing to fit businesses of all sizes

For companies in bustling hubs like Denver Tech Center or expanding organizations looking for a long-term UCaaS partner, RingCentral remains a strong option.

3. Zoom Phone – Beyond Video, Built for Business Voice

While most people know Zoom for its video conferencing, Zoom Phone is their enterprise-grade VoIP solution that’s gaining serious traction in 2025.

Zoom Phone is ideal if:

• You already use Zoom and want to extend it into voice communications

• You need an intuitive, minimal-learning-curve system

• You’re looking for global reach with local support

Zoom Phone is especially useful for smaller Colorado teams that want simple, affordable voice capabilities without sacrificing professional features like auto-attendants, call recording, and voicemail transcription.

4. Microsoft Teams Phone – UCaaS for Microsoft 365 Power Users

If your team lives inside the Microsoft ecosystem, Microsoft Teams Phone might be the logical next step.

Here’s why it’s a top pick for Colorado’s Microsoft-heavy companies:

• Native integration with Microsoft 365 (Outlook, SharePoint, OneDrive, etc.)

• Enterprise-grade security and compliance

• Useful add-ons like call queues, direct routing, and audio conferencing

• Enhanced collaboration inside the same interface your team already uses

Microsoft Teams Phone may require more setup, especially if you’re adding voice services, but for larger Colorado enterprises or state agencies, it’s a natural fit.

5. 8×8 X Series – Versatile and Budget-Friendly for Growing Teams

Rounding out our list is 8×8, a long-time player in the UCaaS market with a focus on global communication and contact center capabilities.

Why 8×8 is a smart choice:

• Affordable plans, especially for SMBs

• Built-in contact center features for sales and support teams

• Video meetings, chat, voice, and team collaboration tools

• Real-time analytics and call quality dashboards

If your business is expanding and needs a solution that can scale up without breaking the bank, 8×8 gives you a strong feature set at a competitive price.

How to Choose the Best UCaaS Platform for Your Colorado Business

Every business has its own communication DNA, which means the best UCaaS solution is the one that meets your specific needs. Here’s what you should consider when evaluating providers:

✅ Geographic Reliability

With Colorado’s varied terrain and unpredictable weather, choose a UCaaS provider that ensures redundancy and consistent uptime, even in remote or mountainous areas.

✅ Integration Capabilities

Will the platform work with the tools you’re already using—like your CRM, email platform, or file-sharing system? Look for open APIs and prebuilt integrations to streamline deployment.

✅ Support That Works When You Do

Colorado businesses span industries from hospitality in Aspen to manufacturing in Pueblo. Your UCaaS provider should offer responsive, U.S.-based support and not just during traditional office hours.

✅ Scalability

Your business might be small today, but what about tomorrow? The right UCaaS solution should grow with you—adding new users, locations, and features as needed.

✅ Security & Compliance

With cyber threats increasing, make sure your provider follows best practices in data encryption, access control, and compliance with industry standards (like HIPAA, SOC 2, etc.).

Why Intermedia is the Standout for Colorado Businesses in 2025

While all five of these UCaaS platforms bring strong capabilities to the table, Intermedia Unite checks the most boxes for Colorado-based organizations, especially those looking for:

• A streamlined user experience

• Reliable uptime with disaster recovery baked in

• Top-tier customer support

• Flexible pricing plans tailored for small to mid-sized businesses

• Strong mobile features for on-the-go professionals

Plus, Intermedia’s all-in-one design eliminates the need for cobbling together separate vendors for email, voice, file storage, and conferencing. That’s a huge time and cost saver for businesses juggling lean IT teams or remote operations.
