## 💻 CODE ARCHITECTURE

FastAPI Application Structure

from fastapi import FastAPI, Form
from fastapi.responses import PlainTextResponse

app = FastAPI(
    title="AI Voice Assistant",
    description="Enterprise Voice Automation Platform",
    version="1.0.0"
)

@app.post("/voice", response_class=PlainTextResponse)
def voice_response():
    """
    Initial voice greeting endpoint
    Handles incoming calls with AWS Polly voice
    """
    return TwiML_XML_Response

@app.post("/process", response_class=PlainTextResponse)
def process_response(Digits: str = Form(...)):
    """
    Process DTMF input from caller
    Routes to appropriate appointment slot
    """
    return Confirmation_Response

Voice Response Flow

1️⃣ Call Initiated → FastAPI /voice endpoint triggered
2️⃣ AWS Polly speaks greeting message
3️⃣ Gather DTMF input (1, 2, or 3)
4️⃣ Process selection → /process endpoint
5️⃣ Confirm appointment with voice response
6️⃣ End call with confirmation
