Contact Center as a Service (CCaaS) is a web-based contact center service which is offered by leading contact center management companies as well as third-party outsourcing contact center vendors. The main advantage of CCaaS over traditional onsite call center support is its lower cost of service. In addition to this, CCaaS is also known as a multi-tiered remote access client site and is also considered to be one of the most robust applications in such kind of contact center.
