Phone Number Setup

You need a phone number routed through Live Hub to your bot:

1. Get a number — In Live Hub, go to Voice Channels → Phone Numbers and buy one (or bring your own SIP trunk via SIP Connections)
2. Create bot connection — Go to Bot Connections → Add new voice bot connection, select AudioCodes Bot API, set your bridge URL (https://your-host:3100/webhook) and BOT_TOKEN
3. Configure speech — Set up STT (e.g. Google Chirp 2, Deepgram Nova-3) and TTS (e.g. ElevenLabs, Deepgram Aura-2) providers
4. Route the number — Go to Routing Rules → Add Rule, set your phone number as source and your bot connection as destination

That's it — calls to that number now hit your AI agent.

Requirements

• OpenClaw instance with /v1/responses API enabled
