Supports Vapi (primary), Bland.ai, and Retell platforms. ### Quick Start 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 ### Platform Comparison FeatureVapiBland.aiRetellBest ForCustom agents, dev-friendlySimple outbound campaignsEnterprise, low latencyLatency~800ms~500ms~500msLanguages100+30+30+Custom LLM✅ Any OpenAI-compatible✅ Limited✅ Via APIPhone NumbersBuy/importBuy/importBuy/importPricing$0.05/min + provider costs$0.09/min all-in$0.07-0.15/minWebSocket✅❌✅Knowledge Base✅ Built-in✅✅Transfers✅✅✅ Recommendation: Start with Vapi — most flexible, best docs, largest community. 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"]}' ### Available Commands python3 {baseDir}/scripts/vapi_agent.py create-agent '{...}' # Create new agent python3 {baseDir}/scripts/vapi_agent.py get-agent # Get agent details python3 {baseDir}/scripts/vapi_agent.py list-agents # List all agents python3 {baseDir}/scripts/vapi_agent.py update-agent '{...}' # Update agent python3 {baseDir}/scripts/vapi_agent.py delete-agent # Delete agent python3 {baseDir}/scripts/vapi_agent.py call '{...}' # Make outbound call python3 {baseDir}/scripts/vapi_agent.py get-call # Get call details python3 {baseDir}/scripts/vapi_agent.py list-calls # List all calls python3 {baseDir}/scripts/vapi_agent.py list-phones # List phone numbers python3 {baseDir}/scripts/vapi_agent.py import-phone '{...}' # Import phone number python3 {baseDir}/scripts/vapi_agent.py update-phone '{...}' # Update phone config ### Credits Built by M.
