What it is #

A test call places a real outbound call to a phone number you enter — with full live visibility into what the AI hears, thinks, and says, in real time on your screen.

When to use it #

  • Before launching a broadcast campaign (always)
  • After editing your agent's skills or knowledge base
  • When debugging "why did the agent say that?" issues
  • When a provider is misbehaving and you need a quick sanity check

How to use it #

  1. 1
    Go to Test Call in the side menu
  2. 2
    Enter a recipient phone number with country code e.g. +14155550123
  3. 3
    Pick the Call Provider
  4. 4
    Pick the Virtual Agent
  5. 5
    Click Make Call
  6. 6
    Your phone will ring within ~2 seconds
  7. 7
    Watch the right-hand pane transcript, AI thinking state, and latency metrics update live

Reading the metrics #

Metric What it means Good target
First Token Time from customer stopped speaking → AI starts replying < 1 second
Response time Time to complete the AI\'s reply < 2 seconds
Duration Total call length

Tips & best practices #

  • If first-token time is > 3 seconds, your provider region is probably far from our servers — try Twilio as a baseline
  • Test your agent's opener, a happy path, an edge case ("I want a refund"), and a hangup
  • Check the transcript afterwards — it's also the data the AI uses for analytics

Troubleshooting #

Problem Fix
Phone rings, no audio Provider SIP/RTP is misconfigured — check Phone providers setup
AI says nothing Check the Virtual Agent has at least one template or prompt attached
Call drops after 10 seconds Recipient\'s carrier is rejecting — try a different number
"Silent return audio" SIP return path blocked — switch provider to Twilio SIP Domain + REGISTER mode
