Suparelay

Make international calls from your AI agent. Suparelay calls any phone number in the world from your browser, with no app to install and no SIM card. The person you call answers on their normal phone. Ask your agent to call a phone number or a country: Suparelay gives the price per minute and a Call link. The link opens the Suparelay dialer in your browser with the number ready, and you make the call on suparelay.app.
