Step 4: Configure Your Agent (Left Panel)

Before writing your prompt, set the basics in the left panel:

FieldWhat to choose
Agent TypeSingle Prompt (already selected)
Call DirectionInbound if customers call in, Outbound if the agent makes calls
Emotive ModelToggle on for more expressive voice (Beta), or leave off
VoicePick a voice from the library — use the preview to listen
Knowledge BaseOptionally attach an existing KB so the agent can use your docs/FAQs

Step 5: Write Your Prompt

The right panel is your prompt editor. This is the heart of your agent — it tells the AI exactly how to behave on every call.

Write clear instructions covering:

  • Role & Objective — Who is this agent and what’s their goal?
  • Conversational Flow — What steps should the agent follow?
  • Dos, Don’ts & Fallbacks — How should the agent behave in tricky situations?
  • End Conditions — When should the call end?

First time? Start simple. Write a few sentences about who the agent is and what it should do. You can refine everything else as you go.


Step 6: Test Your Agent

Click Test Agent in the top-right to start a test call.

You can test your agent in three ways:

  • Web Call — talk to your agent through your browser microphone
  • Telephony Call — enter a phone number and get a call from your agent
  • Chat — text-based conversation with your agent
Test your agent via Web Call, Telephony, or Chat

Talk through a few scenarios — ask a normal question, ask something unexpected, and interrupt mid-response. Listen for clarity and that the agent follows your guidelines.
