# Outbound

`POST /v1/voice/outbound`

## Request body

- OutboundRequest
  - `from_phone_number_id` string, uuid, required — Org-scoped phone number id to dial FROM. Must have an outbound_call agent attached so a SIP outbound trunk has been provisioned.
  - `to_phone_number` string, required — E.164 phone number to dial, e.g. +15555550123
  - `agent_id` string, uuid, nullable — Optional: dial AS this specific agent. Must already be attached to the from-number as an outbound_call binding. Provide this XOR `team_id`; omit both to let the backend pick a bound dialer at random (load-balanced across the fleet).
  - `team_id` string, uuid, nullable — Optional: dial AS this specific team (its default member answers). Must already be attached to the from-number as an outbound_call binding. Provide this XOR `agent_id`; omit both for random pick.
  - `context_variables` object, nullable — Optional seed values for the bound agent's typed context variables, applied once at session bootstrap. Each key must be a variable declared on the agent or one of its bound workflows; values are coerced against the variable's type/enum. An unknown key or an uncoercible value is rejected (422). System vars are frozen on-file; derived seeds satisfy the collection gate. Only honored for single-agent bindings in v1 (ignored for team-bound dialers).
