Hey everyone! I’m building a 95% SMS + 5% voice workflow in VAPI to qualify HVAC leads from Google Ads. The goal is to: Handle most leads via SMS (qualifying, booking appointments). Switch to voice for emergencies (e.g., if a lead says "my AC is broken," the AI texts: "Sounds urgent—can we call to dispatch a technician ASAP?"). Questions: How can I test the SMS workflow to ensure it works correctly before going live? Is the SMS to voice handoff possible in VAPI? For example: If the lead agrees to a call via SMS, can the AI automatically call them? Alternatively, should I route emergencies to a human (e.g., HVAC owner/employee) instead? Would love insights from anyone who’s implemented something similar! Thanks in advance.

For testing your SMS workflow before going live, consider the following steps: 1. Use Development and Testing Tools: - Utilize a testing environment within Vapi or simulate SMS workflows using tools like [Vapi CLI](https://docs.vapi.ai/quickstart/introduction) for local testing. 2. Send Test Messages: - Use test data and scenarios to ensure all SMS responses and interactions align with your workflow design, particularly focusing on the booking appointment process. 3. Integration Verification: - Ensure integration with any external systems, like your CRM or calendar, is working correctly by checking data flow and accuracy. Regarding the SMS to voice handoff in Vapi, you can build a workflow that triggers a phone call when specific keywords or conditions are met in an SMS conversation. Here’s a basic approach: - Keyword Detection: Implement logic in your SMS workflow to detect phrases like "my AC is broken." - Automated Call Trigger: Use Vapi to initiate a voice call to the lead upon detecting emergency keywords, ensuring a seamless transition from SMS to voice. Refer to more detailed workflow construction steps, such as those described in the [Lead Qualification Workflow](https://docs.vapi.ai/workflows/examples/lead-qualification) guide, to set up similar scenarios.
