End node

Use an end node in a Retell conversation flow to terminate the call cleanly, optionally with a closing message generated from a prompt or static text.

The end node ends the call. It’s a terminal node — it has no outgoing edges, and the call ends the moment the agent enters it. You can add as many end nodes as you need, one for each way a call can finish.

By default the agent hangs up immediately, which callers experience as abrupt. Enable Talk While Waiting so the agent says a closing line first.

For example, an appointment-booking flow can end with a static closing line — “You’re all set for Tuesday at 2 PM. Goodbye!” — after the booking succeeds, and use a second end node with a different message on the cancellation path.

Node settings

• Talk While Waiting: When enabled, a text box appears where you define the closing message the agent speaks before hanging up. Choose Prompt to let the LLM generate a farewell from your instruction, or Static Sentence for an exact line like Goodbye, have a nice day.
• Global Node: Make the end node reachable from anywhere in the flow when its condition is met — for example User wants to end the call or says goodbye — so you don’t have to wire an edge to it from every node. Read more at global node.

Custom SIP headers

For phone calls, open the end node’s settings and use Custom SIP Headers to send metadata when this node ends the call. Click Add, enter a header name starting with X- or x-, and set a static value or a dynamic variable such as {{appointment_id}}. Valid edits save when you leave the field.

For example, set X-Call-Outcome to booked on the booking path and cancelled on the cancellation path. Each end node can have its own headers. See end-call SIP headers for naming rules and configuration details.

Configure custom SIP headers in the end node's settings.

End node vs End Call tool

Use an end node when the call should end at a fixed point in the flow. If instead the agent should be able to end the call mid-dialogue whenever it judges the conversation complete, attach an End Call tool to a subagent node.
