Overview

Communications-as-a-Service (CaaS, typically pronounced ‘cass’) is an outsourcing model for enterprise communications. Such communications can include voice over IP, instant messaging, collaboration and videoconference applications using fixed and mobile devices. The CaaS vendor is responsible for all hardware and software management and offers guaranteed Quality of Service. CaaS allows businesses to selectively deploy communications devices and modes on a pay-as-you-go, as-needed basis.

This approach eliminates the large capital investment and ongoing overhead for a system whose capacity may often exceed or fall short of current demand. CaaS offers flexibility and expandability that small and medium-sized businesses might not otherwise afford, allowing for the addition of devices, modes or coverage on demand. The network capacity and feature set can be changed from day to day if necessary so hat functionality keeps pace with demand and resources are not wasted. There is no risk of the system becoming obsolete and requiring periodic major upgrades or replacement.
