Function calls allow the agent to perform real actions such as booking appointments or transferring calls. Without tools, your agent can only respond with words. With tools, it can do things — mid-conversation, in real time, without any human intervention. Tools are added directly inside the Agent Builder. You can combine multiple tools in a single agent to handle complete workflows from start to finish.

Supported Tools

SigmaMind supports five tool types across three categories:

​
🔊 Voice Tools

Control the call flow — where it goes and when it ends.
  • Transfer Call — Route the active call to a human agent or phone number via warm or cold transfer
  • End Call — Hang up and terminate the call cleanly once the conversation is complete
  • Navigate IVR — Automatically handle IVR phone menus on outbound calls using keypad inputs or speech

​
📥 Extract Variables

  • Extract Dynamic Variables— Capture values the customer provides during the call (names, IDs, dates) and store them as {{variable_name}} for use in any subsequent tool or prompt

​
🔗 Integration Tools

  • Add Integration Tool — Connect to external apps and APIs mid-conversation to look up records, create bookings, update data, or trigger any action your connected integration supports

​
How to Add a Tool

  1. Open the Agent Builder
  2. Click + Add Tool
  3. Select the tool type
  4. Fill in the required fields
  5. Click Add to Agent
Every tool has an Instruction field — a plain-language description of when the agent should trigger it. The agent reads this alongside the live conversation and acts when the condition is met.
