What is Vonage?
Vonage provides communications APIs that let developers add voice calls, video, messaging and user verification to their apps. Its developer platform covers a Voice API with speech-to-text and text-to-speech, SIP trunking, a Video API with a low-code Meetings API, and a Messages API for SMS, RCS and WhatsApp.
Beyond the basic channels, Vonage offers the Verify API (including Silent Authentication), Number Insight, Fraud Defender, and carrier network APIs based on CAMARA standards, such as Identity Insights and Location Retrieval. AI Studio is a drag-and-drop tool for building conversational flows and voice bots without much code.
Vonage suits engineering teams building customer communication into products, businesses that need OTP and phone verification, and companies moving off other CPaaS providers. Client and server SDKs, guides for migrating from Twilio, and a free account signup are available.
