Bridge two phone numbers (from_number ↔ destination)

Bridges two phone numbers into one call — your from_number and the destination. Because it rings two phones, it uses TWO concurrent channels. Pass connect_number to ring a separate phone for the human leg (e.g. an agent’s own cell) while the destination still sees from_number; the connect_number is never shown to the destination. For 1-channel calls, use POST /v1/calls (AI outbound — the agent joins over the network) or the WebRTC token flow (a human joins in the browser). Returns immediately with call_id; poll GET /v1/calls/ or subscribe to webhooks for status. Demo keys must target an allowlisted destination.

POST /v1/calls/dial
