Everything you need to build on voice
Production-grade telephony as a clean API. Designed for the African market, built on proven infrastructure.
Inbound & outbound calls
Place and receive calls over the REST API. Webhook-driven: your server tells us how to handle each call.
Simple call-control verbs
Drive calls with plain XML — Say, Play, Dial, Record, Pause, Redirect. No SDK to learn, no state to manage.
Browser & mobile softphones
Give end-users a real phone in your app. Mint short-lived phone tokens on your server — no secret key in the browser.
Real-time event stream
Watch calls live over a WebSocket. Namespaced codes and stable schemas make integrations predictable.
Text-to-speech & recording
Speak text on a call with a single verb, and record calls to storage with signed download URLs.
Pay-as-you-go in KES
A KES wallet, no monthly fees. Calls billed per second, numbers per month. Live monitoring stops runaway spend.
Know what your calls are doing
Subscribe to the event stream and watch calls ring, answer, and complete in real time. Every event carries a stable code — the same code you see on the call record and in webhooks.
