DÓNDE FUNCIONA
TODO LO ESENCIAL
Sinch Voice API is a programmable voice platform that lets applications make and manage calls. It supports outbound and inbound PSTN, SIP, and in-app calling, and adds advanced features like Text-to-Speech (in 115+ languages), IVR menus (with keypad and numerical speech input), call recording, transcription, number masking, and conferencing.
The API follows a request-and-response model:
•Your application sends a command via REST to start or manage a call (e.g., “make a call and play a message”).
•The Sinch platform connects the call across PSTN, SIP, or in-app channels.
•As the call progresses, the platform sends real-time webhooks (callbacks) back to your application (ringing, answered, disconnected, key press, etc.).
•Your application can then decide the next action (e.g., transfer the call, play audio).
Sinch Voice API supports REST APIs, HTTPS, and SIP protocols. It handles PSTN ↔ PSTN, PSTN ↔ SIP, SIP ↔ SIP, App ↔ App, and App ↔ PSTN (WebRTC) call types.
La configuración puede hacerse en cuestión de minutos. Para empezar, crea una cuenta de Sinch, obtén tus claves de API y empieza con llamadas de prueba a tu número verificado, sin necesidad de hardware de telecomunicaciones. En las implantaciones empresariales, la incorporación también puede ser asistida por ventas.
The platform offers global reach with local, mobile, and toll-free numbers in 70+ countries and 16,000+ cities. Infrastructure is distributed across five AWS regions to optimize call quality and reliability.
You can extend calls with features like text-to-speech (TTS) in 115 languages, answering machine detection (AMD), call recording and transcription, IVR (DTMF keypad input and speech recognition for numerical input), number masking, call forwarding, conference calling, and real-time audio streaming for AI and analytics.
Yes. The Voice API platform is ISO 27001 certified, GDPR compliant, STIR/SHAKEN compliant (US/CA), and TLS/SRTP encrypted for signaling and media.
Pricing is usage-based with per-minute charges for inbound and outbound calls plus optional rental of local, mobile, or toll-free numbers. Features like recording, transcription, and AMD are billed separately.
