Properties

Name Type Description
name string Display name for the AI voice agent
system_prompt object Default instructions for the agent's personality and behavior on ALL calls (inbound and outbound). Can be overridden per-call via POST /v1/calls.
initial_greeting object Default opening line spoken on ALL calls (inbound and outbound), e.g. 'Hello, how can I help you today?'. Can be overridden per-call via POST /v1/calls.
voice_id object Voice the agent speaks with: a voice_id from list_available_voices or a legacy preset name (e.g. 'female-1'); defaults to the system voice if not set
speech_language object BCP-47 locale the agent listens and speaks in, e.g. 'en-US', 'hi-IN'. 'auto' (or unset) keeps multilingual auto-detection. Allowed values are listed under 'languages' by list_available_voices.
speaking_speed object Speaking pace multiplier from 0.6 (slower) to 1.5 (faster); 1.0 is the voice's natural pace.
transfer_number object Number a live call is transferred to. Only the owner phone is allowed, so leave it out or send the same E.164 number as owner_phone; setting owner_phone fills it in.
voicemail_message object Message the AI agent leaves if the call goes to voicemail
owner_phone object Owner's phone number in E.164 format (e.g. '+12125551234'). Calls from this number enter task mode. This is also the only number a live call can be transferred to.
