Getting started

Making your first call

Two ways to hear your agent come alive: a free in-browser test (no phone number needed) or a real phone call once you've attached a Twilio number.

Path A - Browser test (free)

Mic + speakers required. No phone number, no charge.

  1. 1Open any agent from your agents list.
  2. 2Click the Test in browser button (top-right of the agent editor).
  3. 3Grant mic permission when your browser asks. We use it for real-time speech-to-text - audio never leaves WebRTC except to the STT provider.
  4. 4Start talking. The agent picks up after the first half-second of silence. End with the red hangup button or close the tab.
Heads up: Browser tests still consume STT + LLM + TTS, so they count against your credit balance at the same per-minute rate as a phone call. The savings are only on telephony + LiveKit minutes.

Path B - Real phone call

Provision a Twilio number, attach it to your agent, dial in.

  1. 1From the agent page, click Buy a number. Pick a country and area code - Floo provisions it through Twilio behind the scenes (~$1.15/mo for US numbers, varies by country).
  2. 2Floo wires the webhook automatically. You don't need to touch the Twilio console.
  3. 3Dial the number from your phone. The agent picks up after one ring with the greeting you configured.
  4. 4Hang up - the call recording, transcript, and per-minute cost breakdown land in Calls within ~10 seconds.
Bring-your-own-Twilio? Yes - paste your Account SID + Auth Token under Settings → Integrations. You'll save the per-minute Twilio markup but lose one-click number purchasing.

Troubleshooting

Why isn't my agent talking?
Three things to check:
  • Mic permission denied - look for a blocked-mic icon in your browser's address bar.
  • The system prompt is empty. Open the agent editor and confirm there's a greeting.
  • Voice provider key missing. Floo uses our pooled key by default; if you swapped to BYOK, double-check it's valid under Settings → Providers.
Why does the call hang up after a few seconds?
Usually it's an insufficient credit balance - Floo terminates calls when your wallet goes below $0.20 to avoid negative balance. Top up under Settings → Billing. If your balance is healthy, check the call detail page - we log the exact reason (provider error, webhook timeout, user-hangup).
My agent sounds robotic / cuts off mid-sentence
You're probably on the Starter tier with a tight interruption threshold. Either:
  • Upgrade to Pro/Business for ElevenLabs voices - much more natural cadence.
  • Tune the interruption sensitivity slider under Advanced settings - default is 0.7, lower it to 0.4 if the agent gets cut off by background noise.
I can't hear the agent in the browser test
Likely an output-device issue, not Floo. Check that your system output isn't muted, that your browser tab isn't muted (right-click the tab → unmute), and that you don't have a headset disconnected mid-session.
