UCaaS vs CCaaS: Choosing Between Unified Communications as a Service and Contact Center as a Service

UCaaS vs CCaaS Comparison: Wildix Headset

The line between telephony and communications is constantly changing, and different companies offer a huge range of services when it comes to UCaaS vs. CCaaS. It’s important to note the differences between them — even as providers gradually produce products in both spaces.

UCaaS Definition: Enhancing Internal Communication and Collaboration

UCaaS is short for “unified communications as a service,” a cloud-based solution designed to provide businesses with a unified platform for voice, video, messaging and collaboration. In addition, it’s “as a service,” so it’s typically paid for as a subscription model, rather than being a much, much larger upfront cost with a small monthly fee for hosting or maintenance. Similarly, it’s often a lighter-weight model with little in the way of downloads or physical infrastructure, although this isn’t always the case. This comprehensive approach improves communication and collaboration among employees, regardless of their location. Key features in UCaaS solutions often include:

  • Voice calling
  • Video conferencing
  • Instant messaging
  • Presence information
  • File sharing
  • Project management tools

These functions can be highly useful in increasing productivity and efficiency, allowing you to do more with less. Even changing something small like having a click-to-call phonebook integrated into your customer relationship management software can result in surprisingly large efficiencies.

Some define UCaaS as only improving internal communication, but that’s not accurate. UCaaS improves communication between teams, whether internal or external — and at Wildix, we use that to our advantage. By creating groups, for example, we can improve communications during sales calls, for example, and ensure everyone is on the same page. In addition, presence information — something that’s harder to replicate with many on-prem systems — can be vital to improving efficiency for both internal and external contacts. Ultimately, it helps improve efficiency across all sectors of the business, whether it’s a sales organisation, another type of business or a public service organisation.

CCaaS Definition: Streamlining External Communication and Customer Service

CCaaS stands for “contact center as a service” (or occasionally, “call center as a service”), a cloud-based solution that focuses on managing contact center operations. Again, the “as a service” part means it’s a subscription. By utilizing CCaaS platforms, businesses can enhance customer service, reduce costs and boost agent productivity. Typical features found in CCaaS solutions include:

  • Voice calling
  • Chat
  • Email
  • Social media integration
  • Knowledge base
  • Reporting
  • Analytics

The difference between UCaaS vs CCaaS can be blurry. Wildix, for example, offers a CCaaS solution called x-caracal, which fulfills many of the contact center functionality that users demand.

Its streamlined approach provides you with an intuitive means of tracking the effectiveness of your customer experience. Armed with these insights, you can then focus on enhancing customer satisfaction and retention, leading to improved business outcomes.

Here are a few important qualities that the x-caracal CCaaS platform has:

Lightweight: x-caracal is a cloud-native browser-based solution that allows you to access contact center analytics instantly, without the need for additional software or hardware. It offers a convenient overview of your contact center data whenever you need it — in-browser, on-tablet or on-phone. If your solution requires a hard client, however, it may affect your ability to access it anywhere.
Agile: With x-caracal’s real-time call center analytics, you can monitor and respond to every aspect of your call flow as data comes in. This agility enables you to make informed decisions and take prompt action to optimize your contact center operations. You need real-time analytics to be able to determine whether you’re hitting your KPIs or not, and a lack can really affect the management of your teams.
Integrated: x-caracal empowers you to take full control of your communications process by monitoring all agents’ devices, including mobile devices. This integrated approach ensures comprehensive visibility into your contact center operations, leading to improved efficiency and performance.

By integrating x-caracal into your Wildix setup, running contact center analytics and reporting becomes effortless. With its seamless, cloud-based deployment, you can quickly leverage the power of real-time call center analytics tools.

Moving Beyond x-caracal for CCaaS

However, x-caracal has its limitations, which is where another solution such as ipSCAPE or Genesys can come in. Rather than looking just at UCaaS vs. CCaaS, it can be helpful to compare a couple of different CCaaS options directly. Genesys and ipSCAPE both integrate with a Wildix PBX, making it easy to incorporate calling and heavy-duty CCaaS solutions into your business with all the convenience of a remote-capable setup.

ipSCAPE encompasses a range of features, including inbound and outbound contact center services, voice campaigns, web chat, and email capabilities. Its versatility extends to APIs and Webhooks, enabling seamless integrations with other systems. The platform also boasts self-service administration and robust reporting functionalities.

A standout aspect of ipSCAPE is its ability to provide a multi-channel customer experience, utilizing advanced integration capabilities with renowned CRM and business intelligence applications. This empowers clients to deliver exceptional customer experiences in both sales and service environments while gaining strategic insights into customer management. Leveraging cutting-edge AI technology and intelligent algorithms, ipSCAPE incorporates innovative features like the Virtual Agent Voice and Predictive Dialler to further enhance its offerings.

Genesys offers a comprehensive contact center software as a service solution, empowering companies to establish highly interconnected experiences. With its all-in-one contact center solution, Genesys enables businesses to create seamless customer interactions. Leveraging integrated AI and automation tools, the platform facilitates predictive engagement, ensuring that agents can efficiently serve customers in the most effective manner. This not only enhances customer loyalty but also drives revenue growth. Genesys provides a range of applications and integrations, simplifying the process of delivering a customized user interface equipped with all the necessary tools. The solutions encompass interactive voice response (IVR), chatbots, and workforce engagement and management tools, further enhancing operational efficiency and productivity.

Both of these CCaaS solutions can be integrated into a Wildix PBX to deliver a highly streamlined system that also allows remote working and effective performance delivery.

Choosing the Right UCaaS vs CCaaS Solution for Your Business

Selecting the ideal platform depends on your business’s specific needs. If you aim to enhance internal communication and collaboration while improving small-scale external communication, UCaaS is a suitable option. However, if your priority is improving customer service for a big team and reducing costs, CCaaS might be the better choice.

Here are the key differences between UCaaS and CCaaS (although they’re not always applicable to every solution!).

UCaaS and CCaaS Advantages

Both UCaaS and CCaaS offer a range of advantages for businesses. These include:

Increased productivity: By providing employees with a unified platform for communication and collaboration, UCaaS and CCaaS enhance productivity. This streamlines operations and saves time and money by eliminating the need for multiple communication tools.

Improved customer service: UCaaS and CCaaS improve customer service by providing customers with various channels to contact businesses. This versatility enables customers to receive prompt assistance when required.

Reduced costs: Both UCaaS and CCaaS solutions eliminate the need for on-premises hardware and software, resulting in cost savings. Businesses can avoid upfront expenses, maintenance costs and upgrade fees, and subscription models tend to be cheaper in the long run.

Increased flexibility: Since UCaaS and CCaaS are cloud-based solutions, they can be accessed from anywhere with an internet connection. This flexibility benefits businesses with remote workers or teams operating from multiple locations. However, there may be regulatory issues (especially in healthcare, finance and legal) that prevent employees from choosing to work from absolutely anywhere.

Great security: Both UCaaS and CCaaS are offered as a service. This means that security updates should be applied regularly to the system. While different vendors have different levels of security, those that patch systems regularly and have a good record of delivering secure systems (preferably secure by design ones!) should be a priority, especially in information-critical environments. Look for solutions with low numbers of CVE issues and low severity — it’s surprising how many exploits are still open on many systems (and even more in unpatched devices!).

Minimal hardware: In many cases, both UCaaS and CCaaS systems need minimal hardware to operate. A great system can run off a phone or a computer, and it has an SBC built in (a session border controller, which prioritises voice network traffic). Ideally, you won’t need a VPN or another bit of software to access your network — these add-ons can create complications that need to be carefully managed. Solutions that require extra hardware (such as an SBC) or VPNs should be reconsidered as they can make remote work much harder.

The Key Takeaways: UCaaS vs CCaaS

The UCaaS vs. CCaaS solution you need will depend on your exact requirements. If you only need a simple contact centre solution, then a UCaaS solution with a small addon, such as Collaboration with x-caracal, might well be the right one for you. If you want something wider-reaching, a suitable CCaaS solution that integrates with your PBX is likely the best solution for your needs.
