Connect Your Bot to Real Calls
in Hours
Deploying Voice AgentsThree steps to connect your voice bot and go live.
Point your voice bot at Acefone's WebSocket endpoint. Authenticate via REST API. Inbound and outbound calls start flowing immediately. WebSocket events handle call state, transfer triggers, and session metadata automatically.
Why Choose AceXWhy developers ship on AceX instead of building infra.
Building PSTN infra from scratch can take months and a lot of resources. With AceX, you skip carrier negotiations, WebSocket bridge engineering, and number management. You get stateless infra with 99.5% uptime, 50ms streaming latency, and native bot-to-agent handoff. One API contract replaces five vendors.
How is Streaming DifferentWhat voice streaming gives your bot that a SIP trunk does not.
Traditional SIP trunks give you a one-way audio pipe. Voice streaming is bidirectional. Your bot sends audio back into the call in real time. That means your voice agent can interrupt, ask follow-up questions, and handle live responses without call drops or re-routing.
