Organizations

An organization owns its API credentials, Voice Agents, AI integrations, SIP trunks, phone numbers, calls, webhooks, and recordings. An organization API token accesses only resources owned by that organization.

​
Voice Agents

A Voice Agent stores instructions, engine selection, audio-related preferences, policies, and provider bindings. Its two engine modes are:
  • Composable: speech-to-text (stt), language model (llm), and text-to-speech (tts) integrations.
  • Realtime: one realtime integration handles an end-to-end realtime voice session.
The readiness endpoint checks that the expected provider roles are bound to verified organization-owned integrations. Editing agent configuration does not retroactively change the active call’s configuration snapshot.

​
AI integrations and tools

An AI integration is an organization-owned provider credential that can be verified and bound to an agent. An agent tool is a permitted action the runtime may execute, subject to its tool definition and security controls.

​
SIP trunks and phone numbers

A trunk represents your SIP connection, including authentication, allowed source networks, traffic limits, and remote SIP endpoints. A number is a BYOC routing identity that may be assigned directly to a trunk. An inbound Voice Agent binding associates the number with a specific agent.

​
Calls and recordings

A call is a durable organization-scoped resource. Inbound and outbound calls record their state, optional Voice Agent association, trunk/endpoint attribution, and timestamps. Supported controls include answering, hanging up, transferring, hold/unhold, playback, recording, and DTMF. Recordings have their own listing and playback API.
