RingCentral vs Vonage: UCaaS Meets CPaaS

RingCentral and Vonage serve different communication strategies. RingCentral is the UCaaS leader focused on unified communications for businesses. Vonage (now part of Ericsson) bridges UCaaS and CPaaS (Communications Platform as a Service), offering both packaged business phone solutions and programmable communication APIs. Your choice depends on whether you need a ready-made platform or developer-friendly building blocks.

Frequently Asked Questions

Is Vonage still a good choice after the Ericsson acquisition?
Yes. Ericsson's acquisition of Vonage in 2022 brought additional enterprise resources and global infrastructure. The Vonage platform continues to operate independently with ongoing product development, particularly in the CPaaS and API space.
When should I choose Vonage APIs over RingCentral?
Choose Vonage when your team needs to embed voice, SMS, or video into custom applications using APIs. If you are building a custom communication workflow (appointment reminders, two-factor auth, in-app calling), Vonage's CPaaS platform is purpose-built for this. RingCentral is better when you want a ready-made phone system.
Can I use both platforms together?
Some organizations do use RingCentral for internal UCaaS and Vonage APIs for customer-facing communication workflows. This approach adds complexity but can be the right architecture for specific use cases. We can help evaluate whether a single platform or hybrid approach makes sense.
Which is more cost-effective?
It depends on your use case. For standard business phone replacement, the platforms are priced similarly. For API-based communication (CPaaS), Vonage's pay-per-use model can be more cost-effective than a per-seat UCaaS subscription. We model the total cost of ownership for both options as part of our free assessment.
