What are Nodes?
Nodes are the fundamental building blocks of your conversation flow. Each node represents a specific step or action in your agent’s conversation, with its own logic, behavior, and purpose.Key Concepts
- Node Type: Determines the node’s functionality (conversation, subagent, function call, logic, etc.)
- Edges: Connections between nodes that define the conversation flow
- Transition Conditions: Rules that determine when and where to move next
- Fine-tuning: Each node can be optimized independently for better performance
Why Use Nodes?
By breaking complex workflows into individual nodes:- Precise Control: Define exact behavior for each conversation scenario
- Better Performance: Fine-tune specific parts without affecting others
- Easier Debugging: Isolate and fix issues in specific conversation paths
- Reusability: Connect nodes in different ways for various flows
Node Types Available
Conversation Nodes
- Conversation Node: Handle dialogue and user interactions without tool calling
- Subagent Node: Handle dialogue and user interactions with tool calling
- Extract DV Node: Extract and store dynamic variables from conversations
Action Nodes
- Function Node: Execute custom functions and API calls
- Code Node: Execute JavaScript code directly without an external server
- SMS Node: Send SMS messages during the call
- MCP Node: Integrate with Model Context Protocol tools
Call Control Nodes
- Call Transfer Node: Transfer calls to other phone numbers
- Transfer Agent Node: Transfer to another agent
- Press Digit Node: Send DTMF tones (press digits)
- End Node: Terminate the call gracefully
Logic Nodes
- Logic Split Node: Create conditional branches based on variables
Add a Node
1
Select node type
Click from the left sidebar to select the node type you want to add. Click on it and it will be added to the canvas.
2
Configure the node
Click on the node, check the settings on the right, and fill in node instructions inside the node. Check out the respective node guide for more details.
3
Add transition conditions as needed
Add edges by clicking on the bottom part of the node and add your transition conditions. Check out the next step for more details.
4
Connect node
Click and hold the circle to start a line that connects this node to other nodes, and other nodes to this node.
