## Understanding the 4 Types of AI Voice Architectures

1. **Lightweight Rule & IVR Bots (e.g. Goodcall):** Best for simple FAQ filtering (hours, address, basic pricing). Setup is fast, but they rely on static scripts and lack real-time dynamic calendar negotiation or complex multi-tier dispatch.
2. **Pay-As-You-Go Metered Voice Agents (e.g. Dialzara):** Best for ultra-low volume solopreneurs under 30 calls/month where low entry fees matter most. However, per-minute billing ($0.45–$0.48/min) causes invoice unpredictability during busy seasonal surges.
3. **Text-Centric Virtual Receptionists (e.g. My AI Front Desk):** Designed to deflect voice callers into mobile links by texting URLs for web booking forms and self-service pages while on the call, rather than completing deep voice scheduling.
4. **Carrier-Grade Telephony Voice AI (e.g. XBert AI):** Engineered on SIP carrier backbones with streaming sub-600ms latency, 2-way live calendar synchronization, automated customer SMS follow-up, and flat monthly billing for predictable ROI.
