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. Template variables work here. Leave it empty to skip the greeting; it is not used in realtime mode. Prompt — instructions for the first conversational turn, the same as an Agent node. 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. Variable extraction — available here as on other prompted nodes.
