# Start Call

> Opens the call and plays the greeting

The Start Call node is the entry point of every workflow. It plays the greeting, then hands the conversation to the rest of the graph.

Every workflow needs exactly one.

## What you configure

**Greeting** — what the agent opens with, spoken by the voice provider or played from a [pre-recorded audio file](/talk/voice-agent/pre-recorded-audio). [Template variables](/talk/voice-agent/template-variables) work here. Leave it empty to skip the greeting; it is not used in [realtime](/talk/configurations/realtime) mode.

**Prompt** — instructions for the first conversational turn, the same as an [Agent node](/talk/voice-agent/agent).

**Delayed start** — waits a set time before the agent speaks.

**Pre-call data fetch** — calls your API before the greeting and merges the response into the call's context. See [Pre-Call Data Fetch](/talk/voice-agent/pre-call-data-fetch).

**Variable extraction** — available here as on other prompted nodes.
