Infobip Voice API provides programmable communications for businesses and developers building voice applications. It supports inbound and outbound calls across PSTN, WebRTC, and SIP, with voice-number provisioning, IVR, click-to-call, number masking, conferencing, recording, and call control. Teams can access the service through APIs for web, iOS, Android, and direct API use, making it suited to applications that need more than basic outbound calling.

Pricing follows a pay-as-you-go model rather than a fixed monthly paid plan. The published pricing approach uses a country- and currency-dependent calculator, so costs are tied to the calling context. There is no free plan, but the product includes a 60-day free trial, giving teams a comparatively long evaluation period before committing to paid usage. This structure fits projects that need to assess voice workflows across specific destinations, numbers, or channels before scaling.

The feature breadth is the main reason to consider Infobip Voice API. Developers can combine call control, dialogs, bridging, conferencing, and recording with media streaming through WebSocket. Speech capture, transcription, and text-to-speech extend the API beyond telephony into voice-enabled applications, while SIP, WebRTC, and SFTP support help it fit into existing technical environments. Choose it when one platform needs programmable calling, speech features, and multiple connectivity options. Teams seeking only a simple calling API may prefer a narrower product with less operational and feature scope.
