Scalability
CCaaS solutions need to scale when customer demand grows. The best providers offer flexible packages and international phone numbers to facilitate on-demand scaling and global expansion.

Reliability
Opt for providers that offer 99.999% uptime—also known as the five 9s—to minimize downtime and the losses that come with it.
Customer support
Just like UCaaS, the best CCaaS providers provide highly available customer support across multiple channels should you need to get in touch.

Advantages of UCaaS solutions
Increased team productivity and efficiency
However, UCaaS solutions offer numerous features that speed up and streamline collaboration workflows.

Better collaboration for distributed teams
Why is this such a big deal? Well, 87% of people who can work from home, do. Infact, it’s the third-highest motivator for employees looking for new roles.
For employees, it offers increased productivity, job satisfaction, and work/life balance benefits. And for companies, it creates a happier (and by default, more productive) workforce, lowering turnover and absenteeism.
Plus, you‘re not bound by geographical limitations. So you can access a much larger talent pool.
Lower costs
Plus, there’s no need to purchase, install, and maintain expensive hardware. All employees need is an internet connection and a VoIP-enabled device.
Employees can even use their own devices to maximize cost-efficiency.
Limitations of UCaaS solutions
- High network dependency: A stable, high-speed internet connection is vital to UCaaS performance. Network disruptions, poor connectivity, and internet outages can degrade call and video quality, and even lead to downtime.
- Potential security risks: Generally, UCaaS solutions are just as secure as on-premises systems. That said, you’re putting full control of your data security into your provider’s hands. Plus, remote working comes with its own security risks, most notably when employees use public Wi-Fi networks.
- User adoption challenges: Adopting new technologies can be difficult for employees who have grown accustomed to your current systems. Without comprehensive training and user buy-in, you risk frustrating and de-motivating teams.
- Interoperability and integration challenges: While many vendors offer plenty of integrations, there’s always the risk that your chosen UCaaS solution lacks interoperability with your current infrastructure and/or tech stack.
Advantages of CCaaS solutions
Limitless scalability and customer satisfaction
And, there’s no need to purchase additional hardware or write off the cost of hardware you no longer need if you scale down. So, you can scale confidently and cost-effectively.
CCaaS solutions are integrated with a bunch of features that help create exceptional customer experiences: AI technologies, skills-based routing, IVR, and more. This empowers agents to meet customer expectations, boosting satisfaction and loyalty.
Better omnichannel customer service experiences
With a singular, unified platform to host all your customer communications, agents can deliver fast, consistent service across channels. Not only can they effortlessly engage with customers on their preferred platform, but they can leverage in-platform data and CRM integrations to get the full context of past interactions.
Enhanced contact center performance
Improved productivity and customer satisfaction
Limitations of CCaaS solutions
- High network dependency: CCaaS platforms are hosted on the cloud, which means they’re heavily dependent on a strong internet connection. You risk hurting the customer experience if you have poor connectivity.
- Integration challenges: Just like UCaaS, the wrong CCaaS solutions may have trouble seamlessly integrating with your current solutions and network infrastructure, leading to decreased performance.
- Potential security risks: CCaaS security is built into the technology and managed by the provider, so you have no control over its quality. This is why it’s so important to choose a reputable provider with enterprise-grade security.
- User adoption challenges: Onboarding employees onto your new technology may take time and effort, reducing time-to-value. The best CCaaS solutions, however, are designed to be intuitive, with a shallow learning curve.
