Merging unified communications (UCaaS) with a contact center (CCaaS) creates an employee-collaboration customer-engagement machine. Agents can quickly connect with internal departments to get the right answer for a customer. Callers get fast service and only need to authenticate themselves once. Integrated communications data means teams across departments and functions are on the same page. And By bundling UCaaS and CCaaS, companies get the functionality of both platforms from one cloud-hosted vendor — one bill to pay, one platform for IT to manage.
