CPaaS (Communications Platform as a Service)
Enrich and improve the customer experience by integrating communications features into your business applications.


What is CPaaS?
Communications Platform as a Service (CPaaS) is a cloud-based delivery model that allows companies to embed extra communication features into existing business applications. It does this by providing communication APIs (Application Programming Interfaces), through which companies can deploy capabilities like voice, video, and SMS.
RingCentral—one of the leading Unified Communications as a Service (UCaaS) providers—also offers a comprehensive CPaaS solution through our Developers platform.
Get access to free communications APIs and embedded communications technology, and easily add voice, SMS, meetings, data, and more to your business apps.
From softphone dialers for instant calls and texts to data analytics for better insight into your workflows, the possibilities are virtually endless.
Access APIs in your production environment with RingEX
Users of RingEX, RingCentral’s comprehensive unified communications platform, get access to our APIs in their production environments as part and parcel of their plans.
That means you get a complete out-of-the-box employee experience solution with APIs for voice, SMS, social messaging, team messaging, video, fax, data, configuration, AI, and more. All starting from just $20 per user, per month.
Or, you can get a watermarked sandbox as a separate development environment to build and test business applications without accessing, impacting, or modifying production data. That’s available at just $10 per month for two included phone extensions, and a further $5 per month for each additional extension.

Is CPaaS for me?
If you want better communication features but you don’t want to part ways with your existing business applications, then CPaaS is for you.
Business apps are the lifeblood of modern companies, whose operations revolve around sales software, CRMs, and other collaboration platforms. RingCentral offers a range of communications APIs for integration into your custom business solutions.
Keep up with the constantly-evolving tech in your industry with Communications Platform as a Service
For companies who want to stay competitive and keep up with tech advancements that are usually reserved for big organizations, CPaaS is heaven-sent.
It’s a faster, more affordable alternative to overhauling your business apps to enable communications features. That makes it perfect for startups and mid-sized businesses who’d think twice about developing their own custom applications.
For example, most businesses run software suites from Google and Microsoft, like Gmail and Office 365. RingCentral has existing integrations that add some of the latest communication features to these commonly-used business apps.
Communications integrations available with RingCentral include:
- Click-to-dial functions for phone numbers appearing in documents, emails, or even web pages.
- A dialer that allows you to call or text from your favorite CRM, like Salesforce.
- Options to schedule, host, or join an online meeting directly from your Google Calendar or Office 365 calendar, so you don’t have to navigate away from the work you’re doing.
Check out our App Gallery to discover how to integrate these features into the productivity apps you’re already using for your business, without exerting too much effort in programming or development.
Do you have custom business applications that you use for your organization? Our communications APIs can help you add features to it.
But CPaaS is more than just a way to add new functions to your applications—it’s also a way to streamline your workflows. You can improve the transition from a business app to a communication function, making it much simpler and easier.
