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

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 |
