FAQ
How are your voice agents different from standard phone bots?
Standard phone menus (IVRs) are rigid and frustrating. I use Vapi and LiveKit to build ultra-low latency voice agents that are interruptible, conversational, and sound virtually indistinguishable from a real human.
Can the voice agent actually book appointments or update my CRM?
Yes. I don't just set up the voice I build the backend logic. Using FastAPI, n8n, and Zapier, I ensure call transcripts, summaries, and extracted data are instantly pushed to your CRM or calendar.
Will the agent know the specific details of my business?
Absolutely. I implement Advanced RAG (Retrieval-Augmented Generation) so your voice agent can securely query your proprietary PDFs, websites, or databases in real-time to answer specific customer questions accurately.
What happens if the AI doesn't know the answer to a question?
I program custom fallback routing. If the agent encounters a situation outside its configured knowledge base, it can seamlessly transfer the call to a live human agent or politely take a detailed message.
Do you handle the server hosting and infrastructure?
Yes. I architect the entire system for high-volume reliability. I deploy the backend logic and custom integrations on secure cloud environments like AWS or Azure, ensuring your agent never drops a call.
Can I choose the voice and language of the agent?
Yes. You can select from a wide range of ultra-realistic, premium voices. I can also configure the agent to understand and speak multiple languages, depending on your target demographic.
