UCaaS vs. CCaaS: What Are the Main Differences?

ucaas vs ccaas

UCaaS and CCaaS are two of the fastest-growing cloud-based communication platforms for businesses today. Nearly 30% of organizations have already implemented a UCaaS solution as their calling platform, with another 26% planning to adopt one in the future.1 Additionally, 32% of organizations with a contact center have adopted CCaaS – more than any other contact center architecture in use.2

But while both UCaaS and CCaaS aim to streamline business communications, they serve very different functions. In this blog, we’ll break down the key differences and similarities between UCaaS vs. CCaaS platforms to help you determine which can meet your organization’s communication needs.

What Is UCaaS?

UCaaS (unified communications as a service) refers to cloud-based platforms that integrate multiple internal communication channels like voice, video, messaging, and conferencing into one interface. UCaaS solutions provide businesses with a complete unified communications solution without the need for costly on-premises PBX hardware.

With UCaaS solutions, all communication features are delivered over the cloud on a subscription basis, enabling businesses to scale communications up or down as needed. Common capabilities offered by leading UCaaS providers include:

  • Voice Calling (VoIP)
  • Audio/Video Conferencing
  • Instant Messaging
  • Call Recording
  • Auto Attendants
  • Visual Voicemail

UCaaS platforms improve workflow collaboration and facilitate easier internal communication between employees across devices. And since users can access UCaaS solutions through desktop or mobile applications, they can use enterprise-grade communication tools from any location.

What Is CCaaS?

CCaaS (contact center as a service) refers to an all-in-one customer engagement platform delivered via the cloud. CCaaS solutions consolidate multiple external communication channels like voice, email, live chat, and social media into one platform for smoother omnichannel customer experiences.

Like UCaaS, CCaaS eliminates the need for on-site telephony hardware. Core capabilities offered by CCaaS platforms include:

  • Omnichannel Routing
  • Interactive Voice Response (IVR) Menus
  • Call Recording
  • Customer Relationship Management (CRM) Integrations
  • Agent Consoles
  • Real-Time Analytics
  • Customer Service AI

CCaaS solutions aim to optimize customer interactions across channels, providing organizations with complete contact center capabilities without major infrastructure investments.

What Are the Differences Between UCaaS and CCaaS?

While UCaaS and CCaaS are both cloud-based communication platforms, they differ significantly in purpose, features, channels, and integrations.


The main difference between UCaaS and CCaaS is their purpose. A UCaaS platform streamlines internal communication between employees inside an organization. CCaaS platforms focus on managing external communications between businesses and customers.


UCaaS solutions emphasize collaboration features to help unite distributed teams and remote workers, including video conferencing, screen sharing, team chat, file sharing, task management, calendars, and more.

CCaaS solutions typically include contact center-specific features like IVR menus, omnichannel routing, call recording, customer service AI, advanced analytics, ticketing systems, and more to improve customer satisfaction and increase customer service team productivity.


UCaaS platforms typically include digital channels like cloud calling, video conferencing, instant messaging, SMS, and team collaboration apps.

CCaaS tools focus on external communication, with digital channels like voice calls, email, live chat, social media messaging, and SMS.


UCaaS solutions commonly integrate with productivity applications like Slack, Google Workspace, Microsoft Teams, and project management tools to unite workflows.

CCaaS tools integrate with CRM platforms like Salesforce, Zendesk, and Freshdesk to unify customer data across channels and interactions.

How Are UCaaS and CCaaS Solutions Similar?

Despite their different focuses, UCaaS and CCaaS platforms share some important similarities, such as:

Cloud-Based Delivery

Both UCaaS and CCaaS are delivered via the cloud, which provides businesses with flexibility and scalability and eliminates the need for on-premises PBX hardware. This cloud-based model enables companies to quickly adjust their communications capacity and features based on evolving needs.

Remote Work Support

UCaaS and CCaaS providers typically include mobile applications for iOS and Android devices, which enable employees and contact center agents to stay connected and productive while working remotely from their own devices.

Subscription-Based Pricing

UCaaS and CCaaS both use a subscription-based pricing model rather than an upfront capital investment. This allows businesses to pay only for what they use each month and scale up or down as needed to optimize costs.

VoIP Capabilities

Most UCaaS and CCaaS platforms include cloud phone service with VoIP calling delivered over the internet, which eliminates the need for landlines and provides cost savings compared to traditional phone systems.

CRM Integrations

Leading UCaaS and CCaaS solutions integrate with popular CRM platforms, which enable businesses to unify their communication and customer data in one place.

Centralized Management

UCaaS and CCaaS solutions both provide centralized, web-based management interfaces, making it easier for administrators to manage features, users, and configurations from a single platform.

What Are the Benefits of UCaaS Platforms?

UCaaS solutions offer several important benefits for businesses, including:

Cost Savings

Many organizations have reported saving between 50-70% on communications after switching to UCaaS.3 UCaaS platforms eliminate the need to purchase expensive on-premises PBX phone systems and calling plans, and the subscription-based pricing model is more affordable than maintaining proprietary hardware and licenses.

Enhanced Collaboration

Unifying communication channels like voice, video, chat, and conferencing improves collaboration across remote and hybrid teams. Features like screen sharing, team chat, and video meetings unite distributed employees.

Simplified Administration

Web-based management portals make it easy for IT teams to administer the unified communications environment and roll out updates quickly across the business.

Greater Scalability

Cloud-based UCaaS solutions allow businesses to easily scale up or down based on monthly usage and needs.

Increased Productivity

Consolidating communication tools into a single interface cuts down on toggling between business applications and streamlines workflows for improved productivity.

Lower Total Cost of Ownership

Without large upfront capital investments in hardware and with lower monthly subscription costs, UCaaS solutions have a lower total cost of ownership (TCO) compared to legacy on-premises systems.

Greater Mobility

74% of U.S. businesses are planning to or have already implemented hybrid work policies.4 With UCaaS mobile applications, employees can stay connected and productive regardless of device or location, enabling businesses to better support alternative work models.

Fast Deployment

UCaaS platforms can be deployed in days or weeks since there is no new infrastructure to install and configure, allowing businesses to enable communication capabilities faster.

What Are the Benefits of CCaaS Platforms?

Similarly, CCaaS solutions provide unique benefits for call centers and customer service teams, such as:

Omnichannel Support

60% of consumers say contacting organizations feels like communicating with separate departments, not one company.5 By unifying communications tools like voice, email, chat, messaging, and social media, CCaaS facilitates a seamless omnichannel customer experience.

Improved Customer Satisfaction

A CCaaS platform enhances the customer journey end-to-end, driving faster resolution times and higher first contact resolution (FCR) rates.

Global Scalability

The cloud-based model of CCaaS allows contact centers to easily scale up or down to meet demand without capacity constraints, ensuring peak periods are easily managed.

Increased Agent Productivity

CCaaS platforms reduce toggling between tools with an integrated agent desktop. Shared knowledge bases also decrease handle times.

Enhanced Analytics & Insights

Around 66% of businesses believe customer interaction analytics are “very exciting” for the contact center.6 Comprehensive CCaaS reporting provides more insight into customer interactions across all channels, enabling data-driven decisions.

Automation & AI Capabilities

Built-in AI, such as chatbots and intelligent routing tools, help reduce handling times and allow the customer support team to focus on issues that require human intervention. Automation tools also help increase efficiency and offer support around the clock by handling routine queries.

Business Continuity

Cloud-based CCaaS solutions facilitate remote contact center operations and disaster recovery without missing a beat.

Stronger Security

Leading CCaaS providers offer guaranteed uptime, geo-redundancy, and enterprise-grade security, which can be difficult for traditional on-premises solutions to match.
