White-label CPaaS Platform with PortaSwitch

Bundle CPaaS with your hosted PBX service, giving your customers the independence to customize call processing flows, implement integrations with external systems, and build mobile apps.

What is CPaaS?

CPaaS (Communication Platform as a Service) is a powerful tool that allows your customers to add real-time communication features to their own business applications. 

They can fully customize their communication stack by mixing and matching the functionalities that work best for them: 

  • video-enabled help desks
  • appointment reminders
  • authentication services
  • call recording
  • social media messages
  • SMS / text message
  • workflow
  • video messaging
  • webRTC-based calling

With PortaSwitch you, as a CSP, can become a provider of CPaaS directly to your customers. Whether to enterprise customers, who are creating a solution for internal use, or to independent software developers (ISVs), who are creating a SaaS product or mobile app.
