export VAPI_API_KEY="your-vapi-api-key" # Create a voice agent python3 {baseDir}/scripts/vapi_agent.py create-agent '{"name":"Sales Agent","firstMessage":"Hi! How can I help you today?","systemPrompt":"You are a helpful sales assistant for Acme Corp."}' # Make an outbound call python3 {baseDir}/scripts/vapi_agent.py call '{"assistantId":"asst_xxx","phoneNumberId":"pn_xxx","customer":{"number":"+15551234567"}}' # List agents python3 {baseDir}/scripts/vapi_agent.py list-agents # List calls python3 {baseDir}/scripts/vapi_agent.py list-calls

Use Bland for simple high-volume outbound. Use Retell for enterprise low-latency needs. See {baseDir}/scripts/voice_comparison.md for detailed breakdown.
1. Choose a Voice
Vapi supports multiple TTS providers: ElevenLabs — Best quality, most natural (recommended) PlayHT — Good quality, lower cost Deepgram — Fast, good for real-time Azure — Enterprise, many languages
2. Configure the Agent
{ "name": "Appointment Setter", "firstMessage": "Hi! This is Sarah from Dr. Smith's office. I'm calling to help you schedule your appointment.", "systemPrompt": "You are Sarah, a friendly appointment scheduler...", "voice": { "provider": "11labs", "voiceId": "21m00Tcm4TlvDq8ikWAM" }, "model": { "provider": "openai", "model": "gpt-4o", "temperature": 0.7 }, "endCallFunctionEnabled": true, "maxDurationSeconds": 300, "silenceTimeoutSeconds": 30 }
3. Prompt Engineering for Voice
Voice prompts differ from text. Key principles: Keep responses SHORT — 1-2 sentences max per turn Be conversational — use filler words naturally ("Sure thing!", "Got it!") Handle interruptions — voice agents get cut off, design for it Confirm understanding — repeat back key info (names, numbers, dates) Include fallback — "I didn't catch that, could you repeat?"
4. Phone Number Setup
# List available phone numbers python3 {baseDir}/scripts/vapi_agent.py list-phones # Buy a number (via Vapi dashboard or API) # Import existing number (Twilio, Vonage) python3 {baseDir}/scripts/vapi_agent.py import-phone '{"provider":"twilio","number":"+15551234567","twilioAccountSid":"AC...","twilioAuthToken":"..."}'
5. Call Handling
Outbound calls: python3 {baseDir}/scripts/vapi_agent.py call '{"assistantId":"asst_xxx","phoneNumberId":"pn_xxx","customer":{"number":"+15551234567"}}' Inbound: Assign agent to phone number in Vapi dashboard, or via API: python3 {baseDir}/scripts/vapi_agent.py update-phone '{"id":"pn_xxx","assistantId":"asst_xxx"}'
Voice + CRM (GHL)
Voice agent qualifies lead on call Use Vapi's serverUrl webhook to capture call data On call end → create/update GHL contact Move opportunity to appropriate pipeline stage Schedule follow-up if needed
Voice + Calendar Booking
Agent checks availability via calendar API Uses function calling to book appointment Confirms date/time verbally Sends SMS confirmation after call
Voice + Knowledge Base
Upload documents to Vapi's knowledge base for RAG: python3 {baseDir}/scripts/vapi_agent.py create-kb '{"name":"Product FAQ","files":["faq.pdf"]}'
