Rising interest in and use of CPaaS for business communications is raising questions as to how it relates to UC solutions and services already deployed at enterprises. In many instances, the two will remain distinct services sold to very different buyers. But they will increasingly become intertwined as providers use one to enhance the other.


  • CPaaS has become an overly generalized term, and as a result applies to providers and services that are not always directly comparable.
  • Enterprises are a secondary market for most CPaaS providers, but this will change over the next few years.
