AssistantFleet

Select an assistant or create a new one.

Assistant

Name * Instructions (system prompt)

Describe the business, goals, policies, and workflow. AssistantFleet adds a natural phone-conversation scaffold for pacing, turn-taking, exact details, tools, and fallbacks.

First message (greeting)

Greeting delivery

Model

Voice

Input transcript model

Controls caller transcripts and call logs. The Realtime assistant hears the original audio directly.

Turn detection

Semantic VAD eagerness

Semantic VAD is less likely to cut callers off mid-thought. Eagerness applies only to semantic VAD.

Reasoning effort

Max output tokens

Reasoning effort applies to GPT-Realtime-2 models. Higher levels may improve complex workflows but add latency and cost.

Allow the assistant to hang up via the end_call tool Allow the assistant to press touch-tone keys (send_dtmf) — useful for navigating IVRs on outbound calls Transfer numbers (E.164, one per line)

If set, the assistant gets a transfer_call tool restricted to these destinations.

Voicemail behavior (outbound)

Voicemail message (used when leave_message)

Bound numbers

Calls to these phone numbers route to this assistant. Pick the telecom provider that owns the number.

Place an outbound call

Dial out from one of this assistant's bound numbers. Requires TELNYX_CONNECTION_ID set on the server.

Tools

The assistant can call these mid-conversation. Create tools in the Tools tab first, then check the ones to enable here.

Knowledge

Attached documents are injected into the system prompt every call. Create them in Knowledge.
