The End Call stage terminates the conversation with a farewell message. It’s a terminal node with no outgoing connections.

​
Overview

Use End Call nodes to:
  • Gracefully conclude conversations
  • Deliver closing messages
  • Mark successful or unsuccessful call outcomes
End Call nodes are colored red to indicate they’re terminal points in your flow.

​
Configuration

​
Farewell Message

The final message spoken before the call ends. Examples: 
// Standard
"Thank you for calling Acme Corp. Have a great day!"

// After successful resolution
"I'm glad I could help today. Thanks for calling, and have a wonderful day!"

// After appointment booking
"Your appointment is confirmed. We look forward to seeing you. Goodbye!"

// Professional
"Thank you for contacting us. If you have any further questions,
please don't hesitate to call back. Goodbye."

​
End Condition Prompt

An optional LLM-evaluated condition for when to end. This is useful when the End Call node is reachable through multiple paths and you want additional validation. 
End the call when the customer has confirmed they have no more questions
and has said goodbye.

​
Multiple End Call Nodes

You can have multiple End Call nodes in a flow for different outcomes: 
┌─────────────────┐
│   Conversation  │
└────────┬────────┘
         │
    ┌────┴────┐
    │         │
    ▼         ▼
┌────────┐ ┌────────┐
│End Call│ │End Call│
│Success │ │ Failed │
└────────┘ └────────┘
Use cases:
  • Successful vs. unsuccessful resolutions
  • Different farewell messages for different paths
  • Tracking call outcomes in analytics

Best Practices

Keep It Brief

Long farewell messages feel unnatural. Aim for 1-2 sentences.

Match the Outcome

Successful calls deserve positive messages. Failed resolutions should acknowledge the issue.

Include Next Steps

If applicable, tell the caller what happens next (email confirmation, callback, etc.).

Brand Consistency

Use farewell messages that match your brand voice and the rest of the conversation.
